It features a waterproof, rugged design for heavy duty use. Proper use and care of this meter will provide many years of reliable service. Safety This symbol adjacent to another symbol, terminal or operating device indicates that the operator must refer to an explanation in the Operating Instructions to avoid personal injury or damage to the meter. This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury. This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product. This symbol advises the user that the terminal(s) so marked must not be connected to a circuit point at which the voltage with respect to earth ground exceeds (in this case) 1000 VAC or VDC. This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. For maximum safety, the meter and its test leads should not be handled when these terminals are energized. This symbol indicates that a device is protected throughout by double insulation or reinforced insulation. 2.1FCCComplicanceThisdevicecomplieswithpart15oftheFCCRules.Operationissubjecttothefollowingtwoconditions:1.Thisdevicemaynotcauseharmfulinterference.2.Thisdevicemustacceptanyinterferencereceived,includinginterferencethatmaycauseundesiredoperation.ThisequipmenthasbeentestedandfoundtocomplywiththelimitsforaClassBdigitaldevice,pursuanttopart15oftheFCCRules.Theselimitsaredesignedtoprovidereasonableprotectionagainstharmfulinterferenceinaresidentialinstallation.Thisequipmentgenerates,uses,andcanradiateradiofrequencyenergyand,ifnotinstalledandusedinaccordancewiththeinstructions,maycauseharmfulinterferencetoradiocommunications.However,thereisnoguaranteethatinterferencewillnotoccurinaparticularinstallation.Ifthisequipmentdoescauseharmfulinterferencetoradioortelevisionreception,whichcanbedeterminedbyturningtheequipmentoffandon,theuserisencouragedtotrytocorrecttheinterferencebyoneormoreofthefollowingmeasures:•Reorientorrelocatethereceivingantenna.•Increasetheseparationbetweentheequipmentandreceiver.MAX

AUTORANGING/MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following: 1. Press the RANGE key. The “AUTO” display indicator will turn off. 2. Press the RANGE key to step through the available ranges until you select the range you want. 3. To exit the Manual Ranging mode and return to Autoranging, press and hold the RANGE key for 2 seconds. Note: Manual ranging does not apply for the Temperature functions. MAX/MIN 1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display icon "MAX" will appear. The meter will display and hold the maximum reading and will update only when a new “max” occurs. 2. Press the MAX/MIN key again and the display icon "MIN" will appear. The meter will display and hold the minimum reading and will update only when a new “min” occurs. 3. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.
Relative mode The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current, etc. can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value and the measured value. 1. Perform the measurement as described in the operating instructions. 2. Press and Hold the REL button to store the reading in the display and the "REL" indicator will appear on the display. 3. The display will now indicate the difference between the stored value and the measured value. 4. Press and Hold the REL button to exit the relative mode. PEAK HOLD The Peak Hold function captures the peak AC voltage or current. The meter can capture negative or positive peaks as fast as 1 millisecond in duration. Press the PEAK button. “PEAK MAX” will appear in the display, Press the PEAK key again and the display icon "PEAK MIN" will appear. The meter will update the display each time a higher positive and nagetive peak occurs. Press and hold the PEAK button for 2 seconds to exit the mode. DISPLAY BACKLIGHT Press the HOLD/ key for >2 second to turn the backlight on. The backlight will automatically turn off after 10 seconds. HOLD The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the HOLD function. LOW BATTERY INDICATION When the low battery + icon appears in the display, the battery should be replaced. AUTO POWER OFF The auto off feature will turn the meter off after 15 minutes. To disable the auto power off feature, hold down the MODE button and turn the meter on. “APO d” will appear in the display. Turn the meter off and then on again to re-enable the auto power off feature.
Maintenance WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and fastened securely. This MultiMeter is designed to provide years of dependable service, if the following care instructions are performed: 1. KEEP THE METER DRY. If it gets wet, wipe it off. 2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can shorten the life of the electronic parts and distort or melt plastic parts. 3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic parts or the case. 4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning solvents, or detergents. 5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or weak batteries so they do not leak and damage the unit. 6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be removed to prevent damage to the unit. BATTERYINSTALLATIONWARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. Turn power off and disconnect the test leads from the meter. 2. Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver. 3. Insert the battery into battery holder, observing the correct polarity. 4. Put the battery cover back in place. Secure with the screws.
