safetyinformationbeforeoperatingthisinstrument.

• Safetyistheresponsibilityoftheoperator!

• Testsaretobecarriedoutonlyondeadcircuits!Check

forlivecircuitsbeforemakingresistancemeasure-

ments(safetycheck).

• Thesemegohmmetersareratedfor600VCATIIor

• TheMegohmmeterModels6501/6503aresources

ofhighvoltage,asisthesampleconnectedtothem.

Allpersonsperformingorassistinginthetestsmust

employallsafetyprecautionstopreventelectrical

shocktothemselvesandtoothers.

• AEMC

tobeanexcellentsafetypracticeeveniftheequipment

isproperlyoperatedandcorrectlygrounded.

• Whentestingcapacitancesamples,makesurethat

theyhavebeenproperlydischargedandthattheyare

safetotouch.Dielectricinsulationsamplesshouldbe

short-circuitedforatleastvetimestheamountoftime

symbol may be dangerous.

In conformity with WEEE 2002/96/EC

1.2 Denition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

CHAPTER 2

PRODUCT FEATURES

2.1 Description

The AEMC® Models 6501 and 6503 are compact, self-contained

hand-crankedmegohmmeters.Theyarepracticalanddependable

instruments designed for a broad range of plant and eld service

applications,suchasacceptancetestingandpreventivemaintenance

ofwiring,cables,switchgear,andmotors.Theeasyhand-cranked

operationprovidesasteadyrectiedDCvoltageoutputacrossthe

entirerangeforconsistentlyreliablereadings.

Thesemegohmmetersincorporateabuilt-ingeneratorand a con-

stantDCvoltagecircuit to provide astableoutputand give direct

insulationresistancereading.

TheModels6501/6503haveauniqueauto-rangingfeature which

expands the scale by x10 and almost doubles the scale length.

Whenthepointerreachesneartheendofscale,theauto-ranging

featureactivates,returningthepointertothebeginningofthescale

withthex10redLEDindicatoron.

Insulation resistance is indicated with a rugged taut-band meter

movement on a logarithmic scale. The indicator scale is easy to

read.
