(yellow background) at 500V and 1000V (Model 1015). The Ωscale is
linearwitharangefrom0to10Ω(whitebackground).
Tousethe0to1000ΩscaleontheModel1015,takethereadingonthe

OPERATION
4.1 Safety Check (Voltage Test)
WARNING: MAKE SURE THE JACKSARE FIRMLY INSERTED
INTOTHETOPOFTHEMEGOHMMETERPRIORTOPERFORM-
INGANYELECTRICALTESTS!
Before measuring insulation resistance, conrm that the sample is fully
discharged(particularlyindielectricandcapacitancesamples),andthat
thesampleisnotconnectedtoanenergizedcircuit.
To perform the voltage test:
• SettherangeselectiontoMΩ500VorMΩ1000V(Model1015only)
• Connectandreadonthevoltagescale(600VACmax)
Youdonotneedtopresstheyellowbuttontomeasurevoltage.
NOTE: IfmeasuringvoltageonaDCcircuit,thepointerwilldeect
butthemeasurementmaybeinaccurate.
4.2 Insulation Resistance Testing (MΩRange)
After checking for a live circuit (see Safety Check above), connect the
megohmmeter.
SeveralconnectionexamplesareillustratedinFigures3through10.
4.2.1 Test Voltage
Nopublishedstandardtellswhichvoltagetochooseforanygivenwinding.
However,publishedrecommendationscouldbesummarizedasfollows:
Rated Voltage of Motor Test Voltage
Below115 250V
115 250Vor500V
230 500V
460 500Vor1000V

10 Megohmmeter Models 1005 and 1015
4.2.2 Spot Testing
Asageneralruleinspottesting,testvoltageshouldbeapplieduntilno
variation in reading is noted for 15 seconds, or applied for a xed 60
seconds.
What minimum value should be measured?
TheIEEEstandardNo.43-1974statesthatitisimpossibletospecifythe
valueofinsulationresistanceatwhichawindingwillfailelectrically,buton
motors,minimumreadingsgenerallystatedare:
Rated Voltage R Minimum
250 or less 2MΩ
460 2MΩ
Thereisnoxedgurefordeterminingwhatisgoodandbadinresistance
readings,but a goodguidewouldbe1megohmfor every onehundred
appliedoperatingvolts,asaminimumgure.Thisappliestomotorsand
transformers. When the insulation resistance gets this low, an electri-
calbreakdowncanbeexpectedatanytime,andrewindingorreplacing
shouldbeconsidered.
Itisnotunusualfora winding to be 10 to 100 timestherecommended
minimumvalue(IEEEStd.#43-1974:Recommended Practice for Testing
Insulation Resistance of Rotating Machinery), but this varies with tem-
peratureandhumidity.
4.2.3 Ratio Testing
Intimeresistancereading(DielectricAbsorptionRatio),readingsaretaken
at30and60secondstoobtainthedielectricabsorptionratio.
Insulationresistance@60s=DielectricAbsorptionRatio(DAR)
Insulationresistance@30s
Thistestisusefultoincreasetheaccuracyofspottesting.Ingeneral,a
ratioof1.25:2orbettershouldberequired.Aratiobelowthisindicatesthat
repairisprobablyneeded.
Remember,aDCinsulationtestmaybeusedforacceptancetesting,but
ismorecommonlyusedtocheckthegradualdeteriorationofequipment
overitslife.Consultyourequipmentmanufacturerforspecictestortest
voltageifnotknown.
Insulationresistancedecreaseswithmoisture,temperatureandageand
shouldberecordedovertimeatagiventemperatureandcorrected.

4.2.4 Tips For Successful Insulation Resistance Testing
• Check with the equipment manufacturer for factory insulation
resistancereadings.
• Donotrelyoninsulationresistancetestingaloneasproofofwind-
ingconditions.
• Donotexpectthesamevalueforallpartsofallmachines.
• Observe consistent test time duration, recognizing that total
currentthroughinsulationundertestwillvarywithtime.
• Correctallreadingsproperlytoastandardreferencetemperature
(seeIEEEStd.#43-1974,TemperatureCorrectionCurve).
• Knowwhatyouaretesting.Isolatethepieceofequipmentfrom
othercircuitry.
• Watchtrendsratherthanrelyingonsingle“spot”readings.
4.2.5 Insulation Measurement - Connections
Figure3showstheconnectionstomeasuretheinsulationofoneconduc-
tor to the other conductors. The cable should be disconnected at both
endstoavoidleakagethroughswitchboardsandpanels.

Figure 7 shows the connections for
measuring the insulation of a three-
phase line to ground by connecting
thejumpersbetweenphases.
Thisgivesareadingofallconductors
at once. If a load such as a motor,
heater, etc., is attached to the other
end of the line, it will read the load
resistance to ground at the same
time.
By removing the jumpers, readings
canbemade between the individual
conductorsandground.

4.3 Continuity
Measurements
Onceithasbeenveriedthat
no voltage is present, the
continuitycheckmaybeper-
formed.
• Settheswitchtothe10Ω+
position. The measure-
ment is done automati-
cally;you do not need to
press the yellow button.
• Read the value on the
whitescale0to10Ω.
• Settheswitchtothe10Ω–positionandmakesurethattheneedleof
theinstrumentreadsthesamevalue.Ifthesecondvalueisdifferent
fromtheprecedingone,addupthetworeadingsanddividebytwo.
Thereasonfortakingtwodifferentreadingsistocomplywiththeinter-
nationalstandard VDE 0413-4. If your work does not require you to
conformtothisstandard,onlyonemeasurementisnecessary.
• Returnto“OFF”afteruse.
NOTE: For better measurement accuracy on the 10Ω+ and the
10Ω–ranges,measuretheresistanceoftheleadsbyshort-circuit-
ingthem,thensubtractthisvaluefromthemeasuredvalues.
4.4 Resistance Measurements (Model 1015 Only)
• Settheswitchtothe1000Ωposition.Themeasurementisdoneauto-
matically;you do not need to press the yellow button.
• Readthevalueonthewhitescale0to10Ω,thenmultiplythereading
by100togettheactualvaluemeasured.
• Returnto“OFF”afteruse.

MAINTENANCE
5.1 Maintenance
WARNING:
• Formaintenanceuseonlyspeciedreplacementparts.
• To avoid electrical shock, do not attempt to perform any servicing
unlessyouarequaliedtodoso.
• Toavoidelectricalshockand/ordamagetotheinstrument,donotget
waterorotherforeignagentsintothecase.TurntheinstrumentOFF
anddisconnecttheunitfromallthecircuitsbeforeopeningthecase.
5.1.1 Battery Test
Checkthatthebatteriesareingoodworkingconditionpriortousingthe
instrument.
With the switch in the OFF position, press the yellow button:
• Thebatteriesaregoodiftheneedleisinthegreenzone.
• The batteries need replacement if the needle is in the red zone or
lower.
The average battery life is:
• 1000insulationmeasurements
of10secondsontheMΩ-500V
rangeforR=500kΩ.
• 200 insulation measurements
of 10 seconds on the MΩ-
1000VrangeforR=1MΩ.
• 1500continuitymeasurements
of 10 seconds on the 10Ω
range.
NOTE: Theinstrumentwilloperatecorrectlywithabatteryvoltage
rangeof4.5to6.5V.
