Ifthemeasuredinsulationresistanceisgreaterthan2GΩ(2000MΩ),theOLsymbolisdisplayedonthedigitaldisplayinsteadofavalue,andifthemeasurement isgreater than2GΩ, the symbol lightsupontheright-handsideofthebargraph.Similarly,ifthemeasuredinsulationresistanceislessthan50kΩat250V,100kΩat500V,or200kΩat1000V,thedigitalmeasurementdisplayindicates“---”,andifthemeasurementislessthan50kΩ,onlythe symbollightsupontheleft-handsideofthebargraph.

As soon as the yellow button is released the test voltage is stopped(except inTIMERmodewhere it needs to be pressed again), and themegohmmeter returns to the voltage test mode (safety check). It maycontinue to display the voltage, due to the possibly charged sample.The voltage may drop off more or less rapidly based on the samplecapacitance.

When the test voltage is generatedthe symbolisdisplayedtowarntheuserthatthegeneratedtestvoltagemaybedangerous.

Theinstrumentturnson,andallofthedisplaylightsupatthesametimefor1second.Thenfor2seconds,the symbolstayson,andthebargraphand the digital display indicate the remaining battery life in percentage(0to100%,e.g.0.95=95%).Note, that this is approximateandbasedona typical batterywith totalvoltagevaryingfrom6.7to10V.TheinstrumentmaybeturnedoffatanytimebyturningtherotaryswitchtoOFF.Thiscutsoffthebatterypowersupplytothewholeinstrument.

2.6.2 Auto OFF FunctionAfter5minuteswithoutanyoperationtotheinstrument(buttonpressed,or on the remote control test probe, or turn of the rotary switch), theinstrumentautomaticallyentersastand-bymode.

To start up the instrument again do one of the following:• Pressanyoneofthebuttons• Turntheswitch• Presstheyellowtestbuttonontheremotecontroltestprobe

TheAutoOFFisdisabledwhenmeasuringcontinuity,foraslongasthetest current varies from zero (which means that a measurement is inprogress).On theModel1045, in theTIMERmode (see§2.6.7), thefiveminutessteadystatebeginsattheendofthemaximum15-minutemeasurementperiod.

2.6.4 Buzzer• The Different SoundsWhenthe symbolisdisplayed,thebuzzerisactiveandgivesoutdiffer-entsounds,dependingontheoperationorwarning.

• Short buzz (65 ms at 2kHz):- pushonabutton- autoOFF- leadresistancecompensation- after30s,1minand10minduringTIMEDinsulationresis-

• Disabling/Enabling the BuzzerModel 1030: to disable the buzzer, turn the rotary switch to continuitymeasurement (20Ω),and thenpress theyellow testbutton.Thebuzzersoundsandthebuzzersymbolturnsoff.Toenablethebuzzer,presstheyellowtestbuttonagain,orturnswitchtoOFFandthenbackonagain.Buzzeronisthedefaultmode.

• Programming of the Alarm SetpointsTo program the setpoint press the ALARM button until the “ALARM”symbolisdisplayedandbeepsasecondtime(thesetpointunitwillblink,e.g.MΩ).Thevalueofthesetpointcorrespondingtotheselectedrangeisindicatedonthesmalldigitaldisplay.

The display indicates the following default setpoints settings:• >0.25MΩfortheMΩ-250Vposition• >0.50MΩfortheMΩ-500Vposition• >1.00MΩfortheMΩ-1000Vposition• <10.00kΩforthe400kΩposition• < 2.00Ωforthe20Ωposition

Thesetpointsmaybeprogrammedusingthecursorbuttons(see§2.4.3).Duringprogramming,themegohmmetercontinuesmeasuring.Tosavethesetpointsintomemory,quittheprogrammingmodebyanotherlongpressontheALARMbuttonuntilthesecondbeep.There are limitations on the value of the setpoints.Iftheprogrammedsetpoint is too high, it is corrected when it is stored intomemory: themaximumrangevaluewillbeentered.Forexample, forcontinuitymea-surements, a 30.00Ω setpointwill be stored as 20.00Ω (max value forcontinuity).If thesetpointhasbeen improperly input, it isalsocorrectedwhen it isstoredintomemory:Forexample,002MΩwillbecome2.00MΩ.


• Turning the Alarm ON and OFFTheAlarmcanbeturnedONbyashortpressontheALARMbutton.Thebuzzerbeepsand theALARMsymbol, the<or>symbol,and thepro-grammedsetpointvalueisthendisplayedonthedigitalsetpointdisplay.

TheAlarmcanbeturnedOFFbyasecondshortpress(andonebeep)ontheALARMbutton.TheALARMsymbol,the<or>symbol,andthealarmsetpointwilldisappear.

• Triggering the AlarmWhenasetpoint is reachedand thealarm is turnedon, thebuzzerwillsoundcontinuouslyandtheALARMandthesettingswillflash.

Forexample,whenmeasuringcontinuitywithasetpointwithavalueof>10Ω, theinstrumentdisplays“ALARM>10.00Ω”whenthealarmison.Ifthemeasurementexceeds10.00Ω,acontinuousbeepwillbetriggeredandthealarmdisplaywillflash.

Similarly,ifwhenmeasuringinsulationwithasetpointvalueof<10MΩ,theinstrumentdisplays“ALARM<10.00MΩ”.Ifthemeasurementfallsbelowthisvalue,acontinuousbeepwillbetriggeredandthealarmdisplaywillflash.

2.6.6 Measurement Lead Resistance Compensation(Models 1040/1045)

Testleadresistancemaybeimportantinacontinuitymeasurement,andremoving this resistance improves the measurement accuracy of lowresistances.The lead resistancecompensation feature isonlyactive inthecontinuitymeasurementmode(20Ω).

Tocompensate (offset) the test leads resistance,short-circuit the leadsandpressthe buttonforashorttime(longpress).Whenthecompensa-tionhasbeenrecorded,thedisplayindicates0.00andthebuzzersounds.Fromthismomenton,themeasurementsdisplayedwillbeautomaticallyreducedbythevaluerecordedandthe

Todelete thecompensated lead resistance, remove the test leadsandpressthe buttonforashorttime(longpress).Whentheleadcompen-sationiscancelled,the

OPERATION

4.1 Operation

Turn the rotary switch to the measurement to be performed. Connectthe instrument to thesample tobe tested.Theunitsand the rangeareautomaticallyselectedforthebestreading.

The megohmmeter may be shut downmanually by turning the switchto OFF. Otherwise, the instrument will shut down automatically after 5minutesintheabsenceofanyactionbytheuser(see§2.6.2).

4.2 Insulation Resistance Testing (seepages24&25)

• TurnthemegohmmeterONbyturningtherangeswitchtotheappropri-ate MΩ-Voltagerange.

• Connecttheleadfromthe“+”terminaltotheground/earthpointandtheleadofthe“-”terminallead(orremotecontrolprobe)totheothertestpoint.

• Presstheyellowtestbutton.Keepitpresseddownuntilthemeasure-ment is displayed, or as long as needed. If released, the insulationtestwill stop.The yellow button on the remote control probeworksthe sameway as the yellow test button on themegohmmeter (see§2.4.1).

• Record the insulation resistance value before releasing the testbutton.

• To end the measurement, release the yellow test button. Themegohmmeter thenenters thevoltagedetectionmodeanddisplaysthe voltage at the terminals. If the tested samplewas capacitive, avoltagemayappearanddropoffslowly.Waitforthesampletestedtodischargefully(voltage<25V)beforedisconnectingtheleads.

MAINTENANCE

Useonlyfactoryspecifiedspareparts.Themanufacturerwillnotbeheldresponsible for anyaccident, incident, ormalfunction followinga repairdoneotherthanbyitsServiceCenterorbyanapprovedrepaircenter.

5.1 Battery Replacement

Before anymeasurements,make sure that the symbol is not dis-playedwhenameasurementfunctionisselected.Ifitisdisplayed,changeallthebatteries.

Make sure that none of the terminals are connected and that the switch is set to OFF before opening the battery compartment. Thebattery cover is located on the back of the unit. It can be opened andclosed using a coin or a large screwdriver (1/4-turn captive screw).Toavoiderrors,the symbolonthepower-supplyboardshowsthedirectioninwhichthe2x3AA1.5Vbatteriesshouldbeinserted.Makesurethatyouputthecoverbackproperlyandcloseitafterchangingthebatteries.

5.2 Fuse Replacement

Change the fuse if “FUS”appearson thedigitaldisplayatpoweruporwhenmeasuringcontinuity.Takeallnecessaryprecautionswhenopeningtheinstrument.Itcanbeopenedandclosedusingacoinoralargescrew-driver(1/4-turncaptivescrew).Thefuseisplacedonafuseholderonthepower-supplyboard.

Make sure that none of the terminals are connected and that the switch is set to OFF before opening the back cover. To avoid any errors,thetext“F-0.63A”iswrittennexttothefuseholder.Makesurethatyoureplacethefaultyfusewithfuseofthesameratingandtype.Replaceandclosethecover.
