Sense the capacitance function offer tool for calibration those megaohmmeters and insulation testers which can measure also capacitance. Green LEDstarts light. F.o.Notes: Whenin SHORTmode, groundingoftheLfrontpanel terminal always set ON. Set nominal value the requested capacitor using numerical keyboard and confirmby ENTERbutton. the output terminals currently connected test voltage - Accuracy the set capacitance %. Compare M191 reading UUT specification. Maximum allowed test voltage.10 High capacitancemode - Calibration value the selected capacitor - Vmax. Calibration value the selected position will appear. E. Maximum test voltage 000 VDC. M191 calibrator measures the short current and displays it. Connect UUT the output terminals. Select requested test voltage level UUT. When HVC mode the display shows information follows: Fig. Select resistance range UUT necessary. TypicalshortcurrentofUUTs megaohmmetersisseveralmAmax. Select resistance range UUT necessary.7 HVC High voltage capacitance In High voltage capacitance function (HVC) the calibrator enables connect the output terminals one three high voltage capacitors which are built-in the calibrator. MEATEST, s. - Test voltage. D. Switch the UUT output OFF remove test voltage fromthe output terminals. The calibrator equipped with capacitors with nominal values 10, 50, 100 nF. Use test leads delivered with UUT whenever possible. B. I. UUT starts sourceDCcurrent. C. M191 starts measure short current. Select requested test voltage level UUT. terminal connectedto protection earthpotential. Use only test leads with guaranteed isolation according test voltage range UUT. Start UUT measurements, typically pushing ONbutton the UUT. Operating procedure A.r.
