s.o. Thecapacitancefunctionisdesignedfortestingofinsulationmetersandmegaohmmeters which canmeasure the capacitance test circuit based charging and discharging the circuit. 4. Notes: The capacitancefunction designedfor DCapplications. Depending status, the DAR mode can one following submodes: Operating modes 20 User Manual . DAR (60s) (30s) PI parameter has similar definition. Be aware that the test voltage for high resistance measurements dangerous and can cause electric shock! Testleads deliveredwiththe calibratorareapprovedforapplication upto5kVDC. test voltage not allowed apply. Don'tdisconnecttest wires whenmeasuringisinprocess.8 DPP Dielectric andpolarization parameters DPP function enables direct calibration isolation meters which are equipped with function DAR (dielectric absorption ratio), (polarization index) (polarization ratio). Usetestleads deliveredwith UUTsforhighertest voltages. PI (600s) (60s) PR parameter defined ratio resistance measured after the test voltage connected the measured object and resistance measured 180 after the test voltage connected. When using ACvoltageover 100 Vthe calibratorcanbedamaged. PR (180s) (15s) The calibrator has predefined the time sequences both for DAR and parameters simulate these parameters. M191 Insulation Tester Calibrator________________________ MEATEST.Disconnect M191 output terminals using the button OUTPUT ON. Parameters definition In isolation testers DAR parameter defined ratio resistance R1measured after the test voltage is connected the measured object and resistance measured after the test voltage connected. Any other application not recommended. Disconnection can cause damageofthe calibrator. Similarly the PSP mode the DPP mode is based switching three different values resistance the output terminals predefined time sequence.r. defined ratio resistance R1measured after the test voltage is connected the measured object and resistance measured 600 after the test voltage connected
