Precautions concerning Bluetooth wireless technology
• Use of this technology must be authorized according to telecommunications regulations of the
country where the instrument is being used. Contact your Sokkia agent in advance.
• Sokkia is not liable for the content of any transmission nor any content related thereto. When
communicating important data, run tests beforehand to ascertain that communication is operating
normally.
• Do not divulge the content of any transmission to any third party.
Radio interference when using Bluetooth technology
Bluetooth communication with the SRX uses the 2.4 GHz frequency band. This is the same band used
by industrial, scientific, and medical (ISM) equipment such as microwaves, portable premises radio
equipment (license required) and portable specified low-power radio equipment (license-exempt)
used in factory production lines, etc.
• Before starting transmission, check that operation will not take place within the vicinity of portable
premises radio equipment or specified low-power radio equipment.
• In the case that the instrument causes radio interference with portable premises radio equipment,
terminate the connection immediately and take measures to prevent further interference (e.g.
connect using an interface cable).
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, contact your Sokkia agent.
Although a radio station license is not required for this instrument, bear in mind the following points
when using Bluetooth technology for communication.
●Do not use within the vicinity of the following:
•Industrial, scientific, and medical (ISM) equipment such as microwaves and pacemakers.
• portable premises radio equipment (license required) used in factory production lines etc.
• portable specified low-power radio equipment (license-exempt)
•IEEE802.11b/IEEE802.11g standard wireless LAN devices
The above devices use the same frequency band as Bluetooth communications. As a result, using
the SRX within proximity to the above devices may result in interference causing communication
failure or reduction of transmission speed.
• Refrain from using the SRX within proximity to televisions and radios
Televisions and radios use a different frequency band to Bluetooth communications.
However, even if the SRX is used within proximity to the above equipment with no adverse effects with
regard to transmission, moving a Bluetooth-compatible device (including the SRX) closer to said
equipment may result in electronic noise in sound or images.
4.4 Bluetooth Wireless Technology

4. PRODUCT OUTLINE
Precautions regarding transmission
●For best results
•When using the On-demand Remote Control system, perform communication within a line-of-
sight distance of approximately 300m. The usable range becomes shorter when obstacles block
the line of sight, or devices other than the On-demand Remote Control system, such as PDAs or
computers, are used. Wood, glass and plastic will not impede
communication but the usable
range becomes shorter. Moreover, wood, glass and plastic containing metal frames, plates, foil
and other heat shielding elements as well as coatings containing metallic powders may adversely
affect Bluetooth communication and concrete, reinforced concrete, and metal will render it
impossible. Use a vinyl or plastic cover to protect the instrument from rain and moisture.
•The direction of the Bluetooth antenna can have adverse effects upon usable range. For best
results make sure that the antennas of both the SRX and the companion device are as vertical
as possible and visible to one another. When this is not possible, better results can be obtained
by pointing the antenna vertically towards the ground.
• Perform communication at a distance of 2m or more from electrical devices such as audio-visual
equipment and office automation equipment. In the case of microwave ovens, which are especially
susceptible to interference, this distance should be increased to 3m.
Moreover, operation near televisions and radios may lead to problems with reception.
• Ensure that cellular phones are at least 20cm from the SRX Bluetooth module during operation.
• Change location when proximity to a wireless device or broadcast station results in communication
failure.
When using the SRX near IEEE802.11b or IEEE802.11g standard wireless LAN devices or other
devices that operate on the 2.4GHz ISM band, interference may result, causing transmission speed
to slow or even disrupting the connection completely. Turn off all devices not being used.
●Reduced range due to atmospheric conditions
The radio waves used by the SRX may be absorbed or scattered by water and airborne moisture. The
signal may be weakened by exposure to rain, fog, and moisture from the human body with the limit of
usable range becoming much lower as a result. Moreover, as wireless devices lose signal strength
when close to the ground, perform communication at as high a position as possible.

11.TARGET SIGHTING
The target can be automatically sighted using the Auto Pointing function or manually sighted by the
operator using the peep sight and telescope. The Auto Pointing function automatically sights the target
and does not require you to focus the telescope. The SRX analyses the image of the prism in the field
of view and moves the telescope to sight the center of this prism.
•The search method can be set.
"12.1 Auto Tracking Settings"
Caution
• The instrument emits a laser beam until the center of the prism is sighted.
• Auto Pointing can only be performed when a prism or sheet is used as the target. For reflectorless
measurement, the target must be sighted manually.
• Use reflective prisms/reflective sheets from Sokkia for higher precision measurement.
• Auto Pointing cannot be performed if the prism is located at the zenith. In this case, manually sight
the target.
"11.3 Manually Sighting the Target"
• If more than one prism is located in the field of sight during Auto Pointing, an operation error will
occur and the SRX will not be able to find the target.
• A prism beyond glass cannot be searched because a measurement error occurs.
• If an obstacle blocks the laser beam path between the SRX and the prism, SRX cannot find the
target correctly.
• If strong light shines directly into the objective lens, measurement cannot be performed correctly.
• Position the prism in alignment with the objective lens. In short distance measurement especially,
make sure to align the prism with the objective lens (within 10 to 15°) to obtain the correct result. A
prism with a prism constant of -40mm can eliminate the error caused by tilted prism.
Aspect of the 360° Prism
The 360° Prism should be set up so that a pair of hexagonal points on the rubber flanges of the
prism are aligned with the sighting direction of the SRX (see the diagram below).

11. TARGET SIGHTING
• When sighting the target, strong light shining directly into the objective lens may cause the
instrument to malfunction. Protect the objective lens from direct light by attaching the lens hood.
XPROCEDURE
1. Look through the telescope eyepiece at a bright and
featureless background.
Turn the eyepiece clockwise, then counterclockwise
little by little until just before the reticle image becomes
focussed.
Using these procedures, frequent reticle refocussing is
not necessary, since your eye is focussed at infinity.
2. Use the peep sight to bring the target into the field of
view. Turn the vertical and horizontal jogging knobs for
fine sighting adjustments.
3. Turn the telescope focussing ring to focus on the
target.
Turn the vertical and horizontal fine motion screws to
align the target with the reticle.
The last adjustment of each fine motion screw should
be in the clockwise direction.
4. Readjust the focus until there is no parallax
Readjust the focus with the focussing ring until there is
no parallax between the target image and the reticle.
Eliminating parallax
This is the relative displacement of the target image with respect to the reticle when the
observer's head is moved slightly before the eyepiece.
Parallax will introduce reading errors and must be removed before observations are taken.
Parallax can be removed by refocussing the reticle.

12. MEASUREMENT WITH AUTO TRACKING
With the Auto Tracking function, an SRX, sighted on the target using Auto Pointing, will following that
target as it is moved from measurement point to measurmeent point. The On-demand Remote Control
System is recommended for high performance Auto Tracking measurement.
Caution
• The instrument emits a laser beam during Auto Pointing and Auto Tracking operation.
• Auto Pointing can only be performed when a prism is used as the target. Auto Tracking is not
possible with reflective sheet and reflectorless measurement
• Use reflective prisms from Sokkia for higher precision measurement.
• If more than one prism is located in the field of sight during Auto Tracking, an operation error will
occur and the SRX will not be able to find the target.
• The prism beyond the glass can not be searched because measurement error occurs.
• If an obstacle blocks the laser beam path between the SRX and the prism, SRX cannot find the
target correctly.
• Position the prism in alignment with the objective lens. In short distance measurement especially,
make sure to align the prism with the objective lens (within 10 to 15°) to obtain the correct result. A

Lost Prism
In the event that an obstacle prevents the SRX sighting the target during Auto Tracking, the
instrument will predict the direction in which the target will travel and continue Auto Tracking
based on this prediction. If the SRX re-acquires the target in this predicted direction, Auto
Tracking continues without change. If the target is not re-acquired however, Auto Tracking will
stop and the SRX will enter
"prism wait" status for a period of 60 second
s.If the target enters the
field of view or a Turning command is received from the RC Controller during "prism wait", the
SRX will perform Auto Pointing, then resume Auto Tracking. If the target is not re-acquired
during the "prism wait" period, the target is considered "lost" and sighting terminates.

"21.6 Allocating Key Functions"
Caution
• When using the laser-pointer function, be sure to turn OFF the output laser after distance
measurement is completed. Even if distance measurement is canceled, the laser-pointer function is
still operating and the laser beam continues to be emitted. (After turning ON the laser-pointer, the
laser beam is emitted for 5 minutes, and then automatically switches OFF.)
• Make sure that the target setting on the instrument matches the type of target used. SRX
automatically adjusts the intensity of the laser beam and switches the distance measurement
display range to match the type of target used. If the target does not correspond to the target
settings, accurate measurement results cannot be obtained.
• Accurate measurement results cannot be obtained if the objective lens is dirty. Dust it off with the
lens brush first, to remove minute particles. Then, after providing a little condensation by breathing
on the lens, wipe it off with the wiping cloth.
• During reflectorless measurement, if an object with a high reflective factor (metal or white surface)
is positioned between the SRX and the target, accurate measurement results may not be received.
• Scintillation may affect the accuracy of distance of measurement results. Should this occur, repeat
measurement several times and use the averaged value of the obtained results.
Check to make sure that sufficient reflected light is returned by the target sighted by the telescope.
Checking the returned signal is particularly useful when performing long distance measurements.
Caution
• The laser beam is emitted during returned signal checking.
• Manually sight the target when checking the returned signal.
• When the light intensity is sufficient even though the center of the reflective prism and the reticle
are slightly misaligned (short distance etc.), “” will be displayed in some cases, but in fact, accurate

recalled and set as known point data. Residual of each point can be checked, if necessary
• Between 2 and 10 known points can be measured by distance measurement, and between 3 and
10 known points by angle measurement.
• The more known points there are and the more points there are whose distance can be measured,
the higher the precision of the coordinate value calculation.

Precaution when performing resection
In some cases it is impossible to calculate the coordinates of an unknown point (instrument
station) if the unknown point and three or more known points are arranged on the edge of a
single circle.
An arrangement such as that shown below is desirable.
It is sometimes impossible to perform a correct calculation in a case such as the one below.
When they are on the edge of a single circle, take one of the following measures.
(1) Move the instrument station as close as possible
to the center of the triangle.
(2) Observe one more known point which is not on the
circle.
(3) Perform a distance measurement on at least one
of the three points.
• In some cases it is impossible to calculate the coordinates of the instrument station if the included
angle between the known points is too small. It is difficult to imagine that the longer the distance
between the instrument station and the known points, the narrower the included angle between the
known points. Be careful because the points can easily be aligned on the edge of a single circle.

17.SETTING-OUT MEASUREMENT
Setting-out measurement is used to set out the required point.
The difference between the previously input data to the instrument (the setting-out data) and the
measured value can be displayed by measuring the horizontal angle, distance or coordinates of the
sighted point.
The horizontal angle difference distance difference, and coordinate difference are calculated and
displayed using the following formulae.
Horizontal difference
Displayed value (angle) = Horizontal angle of setting-out data - measured horizontal angle
Displayed value (distance) = measured horizontal distance x tan (horizontal angle of setting out data
- measured horizontal angle)
Slope distance difference
Displayed value (slope distance) * = measured slope distance - slope distance setting-out data
* Horizontal distance or height difference can be input in the above formula.
Coordinate difference
Displayed value (coordinates)* measured N setting-out coordinates - N coordinates of setting-out data
* E or Z coordinates can be input in the above formula
Height difference (REM setting out measurement)
Displayed value (height) = measured REM data - REM data of setting out data
• Setting out data can be input in various modes: slope distance, horizontal distance, height
difference, coordinates and REM measurement.
• It is possible to allocate softkeys in the Setting-out measurement menu to suit various applications
and the ways that different operators handle the instrument.

20.SURFACE AREA CALCULATION
You can calculate the area of land (slope area and horizontal area) enclosed by three or more known
points on a line by inputting the coordinates of the points
• Number of specified coordinate points: 3 or more, 30 or less
• Surface area is calculated by observing in order the points on a line enclosing an area or by reading
in the previously registered coordinates and using it as known point data.
• It is possible to allocate softkeys in the MLM menu to suit various applications and the ways that
different operators handle the instrument.
"21. CHANGING THE SETTINGS"
• An error will occur if only two points (or less) are entered (or recalled) when specifying an enclosed
area.
• Be sure to observe (or recall) points on an enclosed area in a clockwise or counterclockwise
direction. For example, the area specified by entering (or recalling) point numbers 1, 2, 3, 4, 5 or 5,
4, 3, 2, 1 implies the same shape. However, if points are not entered in numerical order, the surface
area will not be calculated correctly.
Slope area
The first three points specified (measured/read-in) are used to create the surface of the slope
area. Subsequent points are projected vertically onto this surface and the slope area calculated.

Automatic tilt angle compensation mechanism
The vertical and horizontal angles are automatically compensated for small tilt errors using the
2-axis tilt sensor.
• Read the automatically compensated angles when the display has stabilized.
• The horizontal angle error (vertical axis error) fluctuates according to the vertical axis, so when the
instrument is not completely leveled, changing the vertical angle by rotating the telescope will cause
the displayed horizontal angle value to change.
• Compensated horizontal angle = Measured horizontal angle + Tilt in angle / tan (Vertical angle)
• When the telescope is directed close to the zenith or nadir angle, tilt compensation is not applied to
the horizontal angle.
Collimation correction
The SRX has a collimation correction function that automatically corrects horizontal angle errors
caused by horizontal axis and leveling axis errors.

Atmospheric correction factor
The SRX measures the distance with a beam of light, but the velocity of this light varies
according to the index of refraction of light in the atmosphere. This index of refraction varies
according to the temperature and air pressure.
• To precisely determine the atmospheric correction factor, the average temperature and air
pressure along the measurement beam route must be taken. Take care when calculating the
correction factor in mountainous terrain as the difference in height will result in differences in
atmospheric conditions between two points.
• The SRX is designed so that the correction factor is 0 ppm at an air pressure of 1013 hPa and
a temperature of 15°C.

SRX is a precision instrument that requires fine adjustments. It must be inspected and adjusted before
use so that it always performs accurate measurements.
• Always perform checking and adjustment in the proper sequence beginning from "23.1 Plate Level"
to "23.8 Additive Distance Constant".
• In addition, the instrument should be inspected with special care after it has been stored a long time,
transported, or when it may have been damaged by a strong shock.
The bubble tube is made of glass, so it is sensitive to temperature changes or to shock. Check and
adjust it as outlined below.
PROCEDURE Checking and adjusting
1. Level the instrument and check the position of the
bubble of the plate level.
"9.2 Levelling", steps 3 to 5
2. Turn the upper part of the SRX through 180° and
check the bubble position.
If the bubble is still centered, no adjustment is
necessary.
If the bubble is off-center, adjust as follows.
3. Correct half of the bubble displacement using
levelling foot screw C.
4. Correct the remaining half of the displacement by
using the adjustment pin to rotate the plate level
adjustment screw.
When the plate level adjustment screw is turned in
the counterclockwise direction, the bubble moves
in the same direction.
5. Rotate the top of the instrument and continue
adjustments until the bubble remains centered for
any position of the upper part.
If the bubble does not move to the center even
when the adjustment has been repeated, ask your
Sokkia agent to adjust it.

23. CHECKS AND ADJUSTMENTS
Check and adjust it as outlined below.
• Be careful that the tightening tension is identical for all the adjusting screws.
• Also, do not over-tighten the adjusting screws as this may damage the circular level.
PROCEDURE Checking and adjusting
1. Perform the plate level inspection and adjustment
or carefully use the plate level to level the
instrument.
"9.2 Levelling", steps 1 to 2
2. Check the position of the bubble of the circular
level.
If the bubble is not off-center, no adjustment is
necessary.
If the bubble is off-center, perform the following
adjustment.
3. First confirm the off-center direction.
Use the adjusting pin to loosen the circular level
adjustment screw on the side opposite to the
direction the bubble is displaced to move the
bubble to the center.
4. Adjust the adjusting screws until the tightening
tension of the three screws is the same to align
the bubble in the middle of the circle.

With this option you can check the perpendicularity of the reticle and the horizontal/vertical positions
of reticle lines.
• Check the telescope reticle by manually sighting the target.
PROCEDURE Check 1: Perpendicularity of the reticle to the horizontal axis
1. Carefully level the instrument.
2. Align a clearly visible target (the edge of a roof for
example) on point A of the reticle line.
3. Use the jogging knobs to align the target to point
B on a vertical line.
If the target moves parallel to the vertical line,
adjustment is unnecessary. If its movement
deviates from the vertical line, have your Sokkia
service representative adjust it.
PROCEDURE Check 2: Vertical and horizontal reticle line positions
1. Carefully level the instrument.
2. Install a target at a point about 100m in the
horizontal direction from the SRX.
3. While the Meas mode screen is displayed and the
telescope is in face left, sight the center of the
target and read out the horizontal angle A1 and
the vertical angle B1.

angle A2 and the vertical angle B2.
Example:
Horizontal angle A2 = 198° 34' 20"
Vertical angle B2 = 269° 30' 00"
5. Do the calculations: A2-A1 and B2+B1
If A2-A1 is within 180°±20″and B2(B1 is within
360°±20″, adjustment is unnecessary.
Example:A2-A1 (Horizontal angle)
=198° 34' 20"- 18° 34' 00"
=180° 00' 20"
B2-B1 (Vertical angle)
=269° 30' 00" + 90° 30' 20"
=360° 00' 20"
If the difference is large even after repeating the
check 2 or 3 times, have your Sokkia service
representative perform the adjustment.
147
23. CHECKS AND ADJUSTMENTS
The internal CCD sensor is used for automatic sighting. The offset value is set to correct the position
of the CCD sensor in relation to the telescope reticle, but if for whatever reason the telescope reticle
and CCD camera become misaligned, automatic sighting of the center of the prism cannot be
performed correctly. Check and adjust it as outlined below.
• Perform check and adjustment in weak sunlight and no scintillation.
• It may take up to 20 seconds for an offset value based on the measurement results to appear .
PROCEDURE Checks and adjustments
1. Carefully level the instrument.
2. Position the prism in a horizontal direction
approximately 50 meters from the SRX.
3. Select "Inst.cons." in <Configuration>.
4. Select "CCD-Reticle offset".
23.6 CCD reticle
23. CHECKS AND ADJUSTMENTS

5. Use manual sighting to accurately sight the
target.
"11.3 Manually Sighting the Target"
6. Press [OK].
Press [STOP] to stop the measurement.
7. Offset value (H, V) is obtained from the set offset
value (H, V) and the measurement results. The
offset value is a constant value that indicates the
number of degrees of misalignment between the
center of the telescope reticle and the center of
the CCD sensor. If the offset value obtained from
the measurement result is significantly larger than
the set offset value, press [ESC] and resight the
target.
If the offset value (H, V) obtained from the
measurement results continues to be significantly
large after repeated checks, adjustment is
necessary. Go to step 8.
If one of the offset values exceeds the range, an
error message appears on the screen. Contact
your Sokkia agent to perform the adjustment.
8. Press [OK] to renew the offset value.

23. CHECKS AND ADJUSTMENTS
• Be careful that the tightening tension is identical for all the adjusting screws.
• Also, do not over-tighten the adjusting screws as this may damage the circular level.
PROCEDURE Checking
1. Carefully level the SRX and center a surveying
point precisely in the reticle of the optical
plummet.
2. Turn the upper part through 180° and check the
position of the surveying point in the reticle.
If the surveying point is still centered, no
adjustment is necessary.
If the surveying point is no longer centered in the
optical plummet, perform the following adjustment.
PROCEDURE Adjustment
3. Correct half the deviation with the levelling foot
screw.
4. Remove the optical plummet reticle cover.
23.7 Optical Plummet
23. CHECKS AND ADJUSTMENTS
150
5. Use the 4 adjusting screws of the optical plummet
to adjust the remaining half of the deviation as
shown below.
When the surveying point is on the lower (upper)
part of the illustration:
Loosen the upper (lower) adjusting screw slightly,
and tighten the upper (lower) adjusting screw the
same amount to move the surveying point to a
point directly under the center of the optical
plummet.
(It will move to the line in the figure on the right.)
If the surveying point is on the solid line (dotted
line):
Loosen the right (left) adjusting screw slightly and,
tighten the left (right) adjusting screw by the same
amount to move the surveying point to a point in
the center of the optical plummet.
6. Check to make sure that the surveying point
remains centered on the reticle even if the upper
part of the instrument is rotated.
If necessary, perform the adjustment again.
7. Replace the optical plummet reticle cover.
The additive distance constant K of the SRX is adjusted to 0 before delivery. Although it almost never
deviates, use a baseline with a known distance precision to check that the additive distance constant
K is close to 0 several times a year and whenever the values measured by the instrument begin to
deviate by a consistent amount. Perform these checks as follows.
• Errors in setting up the instrument and reflective prism or in sighting the target will influence the
additive distance constant. Be extremely careful to prevent such errors when performing these
procedures.
• Set up so that the instrument height and the target height are identical. If a flat place is not available,
use an automatic level to make sure the heights are identical.

23. CHECKS AND ADJUSTMENTS
PROCEDURE Check
1. Find an area of flat ground where two points
100m apart can be selected.
Set up the Instrument at point A and the reflective
prism at point B. Establish a point C half way
between points A and B.
2. Precisely measure the horizontal distance
between point A and point B 10 times and
calculate the average value.
3. Place the SRX at point C directly between points
A and B and set up the reflective prism at point A.
4. Precisely measure the horizontal distances CA
and CB 10 times each and calculate the average
value for each distance.
5. Calculate the additive distance constant K as
follows.
K = AB - (CA+CB)
6. Repeat steps 1 to 5 two or three times.
If the additive distance constant K is within ±3mm
even once, adjustment is unnecessary.
If it always exceeds this range, have your Sokkia
service representative perform an adjustment.

The following are all special accessories (sold separately).
• Because all Sokkia reflecting prisms and accessories have standardized screws, it is possible
to combine these prisms, accessories, etc. according to your objectives.
• Because these targets (*2) are coated with fluorescent paint, they reflect when there is little light.
• When using a reflecting prism equipped with a target for distance and angle measurements, be sure
to direct the reflective prism correctly and sight the center of the prism target accurately.
• Each reflective prism (*1) has its own prism constant value. When changing prisms, be sure to
change the prism constant correction value.
• To use the triple prism assembly AP31 or AP32 as a single prism for short distance measurements,
mount the single reflective prism AP01AR in the center mounting hole of the prism holder.

30.EXPLANATION
The 0 index of the vertical circle of your SRX is almost 100% accurate, but when it is necessary to
perform particularly high precision angle measurements, you can eliminate any inaccuracy of the 0
index as follows.
• If the power is cut off, the vertical circle indexing is ineffective. Do it again every time the power is
turned on.
• When indexing the vertical circle, sight the target manually.
PROCEDURE
1. Select “Obs.condition” in <Configuration>. Set “V
manual” (vertical circle indexing method) to “Yes”.
"21.1 Observation Conditions"
<V manual 0 set> is displayed.
2. Carefully level the instrument.
3. Accurately sight a clear target with a distance of
about 30m in the horizontal direction with the
telescope in face left.
Press [OK]. The SRX rotates 180°.
4. Accurately sight the same target and press [OK]
to rotate the SRX 180°. The vertical angle is
displayed.
This concludes the vertical circle indexing
procedure.
30.1 Manually Indexing the Vertical Circle by Face Left, Face
Right Measurement
171
30. EXPLANATION
• Need for atmospheric correction
The SRX measures the distance with a beam of light, but the velocity of this light varies according
to the index of refraction of light in the atmosphere. This index of refraction varies according to the
temperature and pressure. Near normal temperature and pressure conditions:
With constant pressure, a temperature change of 1°: an index change of 1 ppm.
With constant temperature, a pressure change of 3.6 hPa: an index change of 1 ppm.
To perform high accuracy measurements, it is necessary to find the atmospheric correction factor
from even more accurate temperature and pressure measurements and perform an atmospheric
correction.
Sokkia recommends that extremely precise instruments be used to monitor the air temperature and
pressure.
• Finding the average temperature and pressure between two points in different atmospheric
conditions
To precisely determine the atmospheric correction factor, the average temperature and air pressure
along the measurement beam route must be taken.
Determine the temperature and pressure as follows.
Flat terrain :Use the temperature and pressure at the midpoint of the line.
Mountainous terrain :Use the temperature and pressure at the intermediate point (C).
If it is not possible to measure the temperature and pressure at the midpoint, take the temperature
and pressure at the instrument station (A) and the target station (B), then calculate the average
value.
Average air temperature :(t1 + t2)/2
Average air pressure :(p1 + p2)/2
• Calculation of atmospheric correction factor allowing for humidity
30.2 Atmospheric Correction for High Precision Distance
Measurement
30. EXPLANATION
172
The humidity has little influence, particularly on short distance measurements. The effect of humidity
should be considered in cases where it is very hot and humid and high precision measurements are
to be performed over a particularly long distance.
When taking humidity into consideration, enter the atmospheric correction factor calculated using
the following formula.
e (water vapor pressure) can be calculated using the following formula.
t : Air temperature (°C)
p : Pressure (hPa)
e : Water vapor pressure (hPa)
h : Relative humidity (%)
ew: Saturated water vapor pressure
