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.

NOTE: The dielectric discharge test is suited for the insulation measurement of rotating machines, and in general, for the insulation measurement of heteroge-neous or multilayer insulation containing organic materials.

Using the R-DAR-PI-DD Function:Duringoraftermeasurement,theR-DAR-PI-DD buttonallowsyoutoscrollthroughthefollowingvalues:

• DAR(formeasurementslasting>1min)

• PI(formeasurementslasting>theprogrammedPItimes)

• DDcanonlybecalculated1minuteaftertheendoftheinsulationmea-surementandcircuitdischarge,andonlyifitwasselectedbeforebegin-ningthemeasurement.

• CapacitanceinµF(onlyafterthemeasurementhasstoppedandthecir-cuithasbeendischarged)

• ResidualleakagecurrentcirculatingintheinstallationinµAornA

• InsulationresistanceinMΩ,GΩ or TΩ

NOTE: During the measurement, the DAR value is not available if the DD value was preselected before the measurement. The PI value is not available if DAR or DD values were preselected before the measurement.


Automatic Measurement of DAR or PI:

IftheR-DAR-PI-DDbuttonispressedduringthevoltagemeasurementbeforethestartofameasurement,thefollowingisdisplayed:

MΩ DAR PI DD

NOTE: The input current may be a depolarization current resulting from an earlier insulation measurement. It is recommended to start a new DAR and PI measure-ment after the current has dropped to a negligible value (on the order of 100pA) to avoid variations on these measurements.

Dependingonthechoices(DARorPI),themeasurementgoesasfollows:

a) DAR: PressSTART-theDARsymbolflashesandthedisplayindicates“----”aslongasthecalculationoftheratioisnotpossible(t<1mn).

NOTE: If during DAR or PI measurement (automatic or not), a high external inter-ference voltage becomes present, or the insulation resistance goes beyond the device’s measurement range, then the DAR or PI measurements are interrupted and the screen indicates:

NOTE: This adjustment provides the best compromise between the measure-ment build-up time and the presence of external interference voltages (§ 4.2).

Ifnointerferencevoltageispresent,choose0.03toobtainarapidmeasurementbuild-uptime.

Example: If an insulation measurement is performed at a test voltage of 5000V and the limit is set to 0.10, it will be possible to perform a correct measurement with the presence of an external interference voltage ≤500V, to the detriment of a longer measurement build-up time.

WARNING: If an external voltage is present that is greater than the thresholds described in § 4.2, the instrument indicates this voltage on the small display, the warning symbol flashes, and the measurement is stopped.

Note:Thereareseveralspecialfunctionsthatcanbeused(see§2.5).

• Connecttheinstrumenttotheinsulatortobetested.• Start the measurement using the START/STOP button and read the

results.

WARNING: If an external voltage is present that is greater than the thresholds described in § 4.2, then measurement is prohibited.
