Place the prism at the same horizontal distance from the instrument as that of point A0 to measure.
59 ●When measuring coordinate of ground point A1(projection of point A0),set instrument height and prism height. ●When measuring coordinate of point A0,set instrument height only(Prism height is set as 0). ●Under angle offset measurement mode,there are two methods to set vertical angle: 1.Free vertical angle: vertical angle ranges from up-and-down movement of telescope. 2.Lock vertical angle:vertical angle is locked and can’t range from up-and-down movement of telescope. Thus,if collimate A0 with the first method, vertical angle ranges from up-and-down movement of telescope,and meantime slope distance(SD) and elevation difference(VD) will change too.But if collimate A0 with the second method,vertical angle is locked in the direction where prism is located and can’t range from up-and-down movement of telescope.

NOTE: 1）After the adjustment of cross-hair, please check the collimation error and vertical index error. 2) Refer to the chapter “5.9 EDM Optical Axis and the Telescope Sighting Axis Error” to check the axis. At last check the collimator error again.
74 5.6 Horizontal Collimation Error C If the telescope’s sight line isn’t perpendicular to the horizontal axis, the collimation error will appear. The assembling, transportation and operation will cause this error. If the collimation error isn’t over the permitted range, with the program the instrument can correct this collimation error. NOTE: After the program correction this deviation error is also on the instrument. 1) Check (1) Set-up the instrument on tripod or adjustment platform and leveling accurately. (2) Aim at the cross-hairs of collimator or the obvious target at a distance. Get the face left angle reading H1 and the face right angle reading Hr. (3) Calculating the horizontal collimation error C according to C=（Hl- Hr±180°）/2,if C<8″, no adjustment will be necessary. If C>8″, proceed with the following adjustment. 2) Adjustment by program: Set-up the instrument on tripod or adjustment platform, and leveling accurately. Procedures: 1. Power on, run the software “TS810Setup”, on the screen tap ◄ or ► keys until Collimation displays, tap it to display collimation error and vertical index error setting menu. 2. Aim at the cross-hair of collimator at telescope left, tap “Left value” to read the horizntal and vertical angles. 3. Aim at the cross-hair of coillmator at telescope right, tap “Right value” to read the horzontal and vertical angles. 4. The software will calculate the new collimation error and vertical index error automatically. 5. Tap “Enter” to save the new values, or tap “Cancel” to use old values. Note: The adjustment can be performed by the program when C<30″, if C>30″, adjust the
75 reticle. Reticle Adjusting: 1. Rotate the instrument in face right position, turning horizontal tangent screw until Hr′=Hr+C. 2.Loosen the shield of telescope’s reticle. 3. Adjusting two screws at left and at right until the vertical hairs of telescope’s reticle coincides with the cross-hairs of collimator or target. 4. Repeat the check and adjustment procedure until the error is accepted. NOTE: 1. When adjust the screws of reticle, firstly loosen the screw on the moving direction of reticle, secondly tighten another screw by the same mount, clockwise turning is for tightening, and anticlockwise turning is for loosening, the turning mount for tightening or loosening should be same. 2. After the reticle adjustment, it is necessary to adjust the vertical index error by program. 5.7 Vertical Index Error The deviation between vertical circle zero position and horizontal direction is vertical index (i), it is necessary to concern this error when measure vertical angle. The instrument program applied a formula to remove this error. This correction can offer the index for the formula. Warning: Before starting this operation, be sure to read manual carefully, otherwise it may cause data faulty. Because of the close relationship between vertical index and compensator zero position, it is necessary to check and adjust compensator zero position when adjust the vertical circle, the value should be stable when reading. 1) Check: Please adjust the reticle of telescope and correct the collimation error before this operation. (1) Mount the instrument at the tripod or a stable device and level it accurately, then turn on the instrument. (2) Aim at the cross-hairs of collimator or the obvious target at a distance, VA should be
76 about ±10°. Read the face left angle Vl and face right angle Vr. (3) Calculate the index error according to the formula below: i = ( Vl+Vr-360°)/2 (4)If I<10〞, no adjustment is necessary , or you have to adjust it . 2) Adjustment by program: Set-up the instrument on tripod or adjustment platform, and leveling accurately. Procedures 1. Power on, run the software “TS810Setup”, on the screen tap ◄ or ► keys until Collimation display, tap it to display collimation error and vertical index error setting menu. 2. Aim at the cross-hair of collimator at telescope left, tap “Left value” to read the horizntal and vertical angles. 3. Aim at the cross-hair of coillmator at telescope right, tap “Right value” to read the horzontal and vertical angles. 4. The software will calculate the new collimation error and vertical index error automatically. 5. Tap “Enter” to save the new values, or tap “Cancel” to use old values.
77 5.8 EDM Optical Axis and the Telescope Sighting Axis Error It is necessary to check this error after the adjustment of telescope reticle error. 1）Checking (For 350 series) (1) Install the instrument at the tripod or a stable device and level it accurately, then power on the instrument. (2) Set a prism about 2m far away from the instrument. (3) Aim at the prism center with telescope reticle. (4) Enter EDM signal testing screen. (5) Observe through eyepiece, turn the focusing knob until the red mark is clear, if the deviation between mark and cross-hair is not over 1/5 of red mark diameter, adjustment is unnecessary. 2）Checking (For RTS350 series) (1) Install the instrument at the tripod or a stable device and level it accurately, then power on the instrument. (2) Set a reflective sheet about 5m-20m far away from the instrument. (3) Aim at the sheet cross-mark with telescope reticle. (4) Enter EDM signal testing screen. (5) Observe the laser spot, if the laser spot coincides with the cross-mark of reflective sheet, adjustment is unnecessary.
