1.1 International Electrical Symbols

This symbol signifies that the instrument is protected by double or rein-forced 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: Formeasurements performed on circuits directly connected totheelectricaldistributionsystem.Examplesaremeasurementsonhouseholdappliancesorportabletools.

CAT III: For measurements performed in the building installation atthe distribution level such as on hardwired equipment in fixedinstallationandcircuitbreakers.

2.7.6 Alarm Setpoints

Alarm setpoints can only be programmed for insulation and resistancemeasurement.Thesetpointscanbeupperorlowerthresholds.Theycanbe active or inactive and will be stored in the memory even after the instrument has been turned off.

PROGRAMMING OF THE ALARM SETPOINTS

ToprogramthesetpointpresstheALARMbuttonuntiltheALARMsymbolisdisplayedandbeepsasecondtime(thesetpointunitwillblink,e.g.MΩ).Thevalueofthesetpointcorrespondingtotheselectedrangeisindicatedonthesmalldigitaldisplay.

Atthismoment,it ispossibletoprogramthethresholdusingthe►and▲buttons.

During this programming, if you change the switch position, you lose what you have just done.

YoucanquittheprogrammingmodeandrecordthethresholdbyanotherlongpressontheALARMbutton.

5.1 Battery ReplacementBeforeanymeasurements,makesurethatthe symbolisnotdisplayedwhenameasurementfunctionisselected.Ifitisdisplayed,changeallthebatteries. Make sure that none of the terminals are connected and that the switch is set to OFF before opening the battery compartment. Thebatterycoverislocatedonthebackoftheunit.Itcanbeopenedandclosed using a coin or a large screwdriver (1/4-turn captive screw).Toavoiderrors,the symbolonthepower-supplyboardshowsthedirectioninwhichthe6x1.5VAAbatteriesshouldbeinserted.Makesurethatyouputthecoverbackproperly.

5.2 Fuse Replacement (1039)Change the fuse if “FUS”appearson thedigitaldisplayatpoweruporwhenmeasuringcontinuity.Takeallnecessaryprecautionswhenopeningtheinstrument.Itcanbeopenedandclosedusingacoinoralargescrew-driver(1/4-turncaptivescrew).Make sure that none of the terminals are connected and that the switch is set to OFF before opening the back cover.
