Usetestleads deliveredwith UUTsforhighertest voltages. Connect UUT the output terminals. M191 starts measure test voltage and current. Insteadofthis “Err1 Toohigh test voltage! ”isdisplayed. Compare UUT reading M191 set resistance. Test current not displayed when set resistance higher than 300. H. Connect output terminals the M191 pushing the button OUTPUT ON. Operating procedure A. Green LED starts light. G. D. Before the output terminals are switched ONstate, calibrator measures test voltage. Calibrator displays accuracy selected resistance point %. Decrease test voltagebefore continue. - Accuracy. Disconnect M191 output terminals using the button OUTPUT ON.0 GQ. Select HVR mode pushing repeatedly FUNCTION FUNCTION DOWN button until HVRlabel appears the display.Test current displayed only when output terminals are ON. the test voltage is higher than the limits TableII, calibrator does not execute the ONcommand. Use test leads delivered with UUT whenever possible. During the measurement the calibrator goes automatically through sequence statues: OFF, STANDBY, RUNNING, OFF. E. Select requested test voltage level UUT. F. In Timer function calibrator automatically connects the output terminals resistance value 100 MO. M191 calibrator measures the test voltage and display both test voltage and current. Change the resistance value allowedonly when attached test voltage lower than Voin TableII. Activate UUT measurement, typically pushing button the UUT. The value cannot modified.5 TIMER Timer function Timer function allows verify Timer features safety testers and megaohmmeters.r. Use only test leads with guaranteed isolation according test voltage range UUT. Enter requested resistance value using either numerical keyboard rotary button. Notes: Testleads deliveredwiththe calibratorareapprovedforapplication upto5kVDC. Setupresistance not changed. I. the test voltageis over Voandattempt change theresistance isregistered, calibrator doesnot disconnect theoutput terminals andshows errormessage “Err2 Set voltage bellow !”. Confirm the value by pushing the appropriate unit button kQ, MQ, TQ. J. 4. Be aware that the test voltage for high resistance measurements dangerous and can cause electric shock! M191 Insulation Tester Calibrator________________________________________ MEATEST, s. Calibrator can measure time interval for what the UUT test voltage presented the calibrator output terminals. Switch offthetest voltagefirstordecreaseits valuetolevellowerthanshown inthetableII. C.o. Select resistance range UUTif necessary. Don't changesetresistance value when test voltageabove Vois connectedtotheoutputterminals, see tableII. Switch the UUT output OFF remove test voltage from its output. UUT starts source test voltage. 16 User Manual . B
