INTRODUCTION
WARNING
Thesesafetywarningsareprovidedtoensurethesafetyofpersonnel
andproperoperationoftheinstrument.
• Donotattempttoperformanytestswiththeseinstrumentsuntil
youhavereadtheinstructionmanual.
• Safetyistheresponsibilityoftheoperator!
• Tests are to be carried out only on non-energized circuits!
Checkforlivecircuitsbeforemakingresistancemeasurements
(SafetyCheck).
• High voltage is present, as is the sample connected to it.
Anyoneperformingorassistingintestingmustfollowallsafety
precautions to prevent electrical shock to themselves and to
others.
• AEMC®considerstheuseofrubberglovestobeanexcellent
safetypractice,eveniftheequipmentisproperlyoperatedand
correctlygrounded.
• Whentestingsampleswithacapacitivecomponent,makesure
they have been properly discharged and are safe to touch.
Dielectric insulation samples should be short-circuited for at
leastvetimestheamountoftimetheywereenergized.
• Megohmmetersshouldneverbeusedinanexplosiveenviron-
ment.
• Onlyusetheleadsthataresuppliedwiththemegohmmeter.If
theyaredefectiveorworn,replacebeforetesting.
• Thisinstrumentcanbeusedoninstallationsrated for 1000V
CATIIIor2500VCATI.

1.1 International Electrical Symbols
This symbol signifies that the instrument is protected by double or reinforced
insulation.
This symbol on the instrument indicates a WARNING and that the operator must refer
to the user manual for instructions before operating the instrument. In this manual,
the symbol preceding instructions indicates that if the instructions are not followed,
bodily injury, installation/sample and product damage may result.
Risk of electric shock. The voltage at the parts marked with this symbol may be
dangerous.
In conformity with WEEE 2002/96/EC
1.2 Definition of Measurement Categories
CAT II: For measurements performed on circuits directly connected to the
electricaldistributionsystem.Examplesaremeasurementsonhousehold
appliancesorportabletools.
CAT III: Formeasurementsperformedinthebuildinginstallationatthedistribution
level such as on hardwired equipment in xed installation and circuit
breakers.
CAT IV: Formeasurementsperformedattheprimaryelectricalsupply(<1000V)
suchasonprimaryovercurrentprotectiondevices,ripplecontrolunits,
or meters.
1.3 Receiving Your Shipment
• Matchthecontentswiththeorderinginformation.
• Notifyyourdistributorofanymissingitems.
• If the equipment appears to be damaged, le a claim immediately with the
carrierandnotifyyourdistributoratonce.
NOTE: Charge the instrument fully before use.
