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insula-
tion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environment.
• Usetheleadssuppliedwiththemegohmmeters.Iftheyaredefectiveor
worn,replacebeforetesting.
• Thisinstrumentcanbeusedoninstallationsratedfor600V,CategoryIII.
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.

1.2 Definition of Measurement Categories
CAT I: FormeasurementsoncircuitsnotdirectlyconnectedtotheACsupply
wall outlet such as protected secondaries, signal level, and limited
energycircuits.
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
Uponreceivingyourshipment,makesurethatthecontentsareconsistentwiththe
packinglist.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,givingadetaileddescriptionofanydamage.Savethedamagedpacking
containertosubstantiateyourclaim.
NOTE: Charge the instrument fully before use (Model 1060).

1.4.2 Accessory Information
Remote Test Probe
• Theyellowtestbuttongeneratesthetestvoltagewhenpressed.
• The push-button on the back of the probe allows you to light the test point
(approx 500 lux of light). This function is very useful, since insulation testing is
performed on de-energized installations, which can be in a dark area.
DataView®Software (Model 1060)
• Retrievedatafrommemoryandplotgraphsofthechangesininsulationasa
function of the time over which the test voltage is applied, R(t).
• Printoutprotocolsofpersonalizedtests(dependingontheuser’sneeds).
• Createtextlesforuseonspreadsheets.
