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