

PreliminarySafety

When allusingthemeter,observe normalsafetyrulesconcerning:

 Protection      against the dangers of electrical current

 Protection    of the meter against misuse

Whenthe always themeterisdelivered,checkfortransitdamage.Whencheckingvoltage, test 

meteron  a known livecircuitfirst.Testleadsmust        be in good condition. Before use, verify that

thetestlead leadinsulationisintact fromandfree  wireexposureorotherdamage.Useonlythe

suppliedtestleads.

Safetyduringuse

 Be          sure to set the appropriate function and range before use

 Never  exceed the limits        indicated in the specification table of this manual.

 Never touch probes,testleads,oralligator liveclipwhenconnectedto circuit.

 Do         not measure voltage on terminals that exceed 600V above earth ground.

 Always              use caution when working with voltages above 60VDC or 30VACrms. Keep fingers behind probe

barrierwhentakingmeasurements.

 Never                 connect test leads across a voltage source while the rotary switch is in the resistance, continuity, or

diodemodeofoperation.

 Never    perform resistance, continuity, or diodetestsonlivecircuits.

 When  ‐             taking non contact voltage measurements ensure that the positive test lead is NOT exposed and

that the negative(common)test          lead is not connected to the bottom of the meter.

 Before           changing functions using the rotary function dial, be sure to disconnect the meter’s testleads

fromanycircuitundertest.

 Never    use the meter in anexplosiveenvironmentorwheredust, dirt, orsteamexists.

 Never    use the meter if the      housing or battery compartment is open.

 Do          not store meter in direct sunlight, high temperature/humidity, or condensation.

 Ifthe theequipmentis inused  a mannernotspecified by by the themanufacturer, protection provided  

equipmentmaybeimpaired.
