87V ExUsers Manual Ensure the battery door is closed andlatched whenever operating the Meter. Replace the battery as soon as thebattery indicator (M) appears. See“Replacing the Battery” section forinstructions and a list of approvedbatteries. Remove test leads from the Meter beforeopening the battery door. Inspect the test leads for damagedinsulation or exposed metal. Check thetest leads for continuity. Replacedamaged leads before using the Meter. 4Do not apply more than the ratedvoltage, as marked on the Meter,between the terminals or between anyterminal and earth ground.Use caution when working with voltagesabove 30 V ac rms, 42 V ac peak, or 60 Vdc. These voltages pose a shock hazard.Use only the replacement fuses specifiedin this Users Manual. See “Replacing theFuses” section for instructions and a listof approved fuses.Use the proper terminals, function, andrange for measurements. Avoid working alone.When measuring current, turn off circuitpower before connecting the Meter to thecircuit. Remember to place the Meter inseries with the circuit.When making electrical connections,connect the common test lead beforeconnecting the live test lead; whendisconnecting, disconnect the live testlead before disconnecting the commontest lead.Do not use the Meter if it operatesabnormally. Protection may be impaired.When in doubt, have the Meter serviced.Use only a single 9 volt battery, properlyinstalled in the Meter case, to power theMeter. See “Replacing the Battery”section for instructions and a list ofapproved batteries.Only use replacement parts listed in the“Parts” section of this manual. Returnthe Meter to the manufacturer for allother service needs.When using probes, keep yourfingers behind the probe’s fingerguards.
True-rms MultimeterATEX Safety Information Do not use the Low Pass Filter option toverify the presence of hazardousvoltages. Voltages greater than what isindicated may be present. First, make avoltage measurement without the filter todetect the possible presence ofhazardous voltage. Then select the filterfunction.Do not use in wet environments.WCautionTo avoid possible damage to the Meter or tothe equipment under test, follow theseguidelines: Disconnect circuit power and dischargeall high-voltage capacitors before testingresistance, continuity, diodes, orcapacitance.

True-rms MultimeterMaking MeasurementsPower-Up OptionsMaking MeasurementsHolding a button down while turning the Meter on activatesa power-up option. Table 4 includes the power-up options.The following sections describe how to takemeasurements with the Meter.Automatic Power-OffMeasuring AC and DC VoltageThe Meter automatically turns off if you do not turn therotary switch or press a button for 30 minutes. If MIN MAXRecording is enabled, the Meter will not power off. Todisable automatic power-off, refer to Table 4.Input Alert FeatureIf a test lead is plugged into the mA/µA or A terminal, butthe rotary switch is not set to the correct current position,the beeper warns you by making a chirping sound and thedisplay flashes “LEAd”. This warning is intended to stopyou from attempting to measure voltage, continuity,resistance, capacitance, or diode values when the leadsare plugged into a current terminal.W CautionXW WarningTo avoid possible electric shock or personalinjury, never measure voltages greater than65 volts in an Ex-hazardous area.The Meter features true rms readings, which are accuratefor distorted sine waves and other waveforms (with no dcoffset) such as square waves, triangle waves, andstaircase waves.The Meter's voltage ranges are 600.0 mV, 6.000 V,60.00 V, 600.0 V, and 1000 V.
