Safety Precautions

Injuryordeathcanoccurevenwithlowvoltagesandlowcurrent.Itisextremelyimportantthatyouread

thesesafetyinformationbeforeusingyourmultimeter. Followallsafetypracticesandproperoperating

proceduresforequipmentbeingtested.

1.  Exercise extreme caution when: Measuring voltageabove20volts,measuringcurrentgreaterthat10

mA,measuringACpower line with inductive loads, measuringACpowerlineduringelectricalstorms.

2.  Alwaysinspectyourmultimeter,testleadsandaccessoriesforsignofdamageorabnormalitybefore

everyuse.Ifanyabnormalconditions exist (i.e., brokenordamagedtestleads,crackedcase,displaynot

reading,etc.),donotattempttotakemeasurements.

3. Nevergroundyourselfwhentakingelectricalmeasurements. Donottouchexposedmetalpipes,

outlets,fixtures,etc.,whichmightbeatgroundpotential.Keepyourbodyisolatedfromgroundbyusing

dryclothing,rubbershoes,rubbermats,oranyapprovedinsulatingmaterial.

4. Nevertouchexposedwiring, connections, testprobetips, orany live circuit conductorswhen

attemptingtomakemeasurements.

5. Neverreplacetheprotectivefuseinsidethemu ltimeterwithafuse otherthanthespecifiedor

approvedequalfuse. Replaceonlywithsame type of fuses. To avoidelectricalshock,disconnectthetest

leadsandanyinputsignalsbeforereplacingthefuses.

6. Replaceonlywithsametypeofbattery.Toavoi delectricalshock,Disconnectpowercordfromlive

powersource,andthetestleadsandanyinputsignalsbeforereplacingthebattery. 

8. Measuringvoltagethat exceeds the limitsofthemultimeter may damage the meter and exposethe

operatortoashockhazard.Alwaysrecognizethemetervoltagelimitsas statedonthefrontofthemeter.

9.  Neverapplymorethan500VDCbetweentheCOMjackandearthground.

10.Nevertouchavoltagesourcewhenthetestleadsarepluggedintoacurrentjack.

11. Whentestingforthepresenceof voltageorcurrent, makesurethevoltageorcurrentranges are

functioningcorrectly. Takeareadingofaknownvoltageorcurrentbeforeassumingazeroreading

indicatesnocurrentorvoltage.

12.Donotattemptcalibrationorserviceunlesstrainedandanotherperson capableofrenderingfirstaid

andresuscitationispresent.

13.Remember:ThinkSafety,ActSafely.
