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