2 Rearpanel The rear panel the calibrator includes ventilation holes, power cord socket with fuse, mains voltage selector, mains switch, IEEE 488 connectors for connection GPIB bus and type plate with serial number.The function designed calibrate TIMER function UUTs, like HIPOT testers,insulation metes, programmable megaohmmeters, etc. Rear panel 1 air inlet 12 User Manual . Using the function accuracy time interval which the UUT test signal connected its output terminals can easily performed. Using the function capacitance measurement function UUTs megaohmmeters can verified. H igh voltage capacitance The calibrator contains three high voltage capacitors with nominal vales 10, 50, 100 nF. Following parameters are predefined: DAR Dielectric absorption ratio PI Polarization index PR- Polarization ratio P Program able sim ulation polarization/absorption param eters The function enables switch over the output resistance user predefined time from one value to another. The functions enables switch over the output resistance predefined time from one value another value.r.o. four different resistance values can step step connected the output terminals selected time intervals. D Sim ulator polarization/absorption param eters The function can simulate various polarization/absorption indexes often built-in the UUTs. 3. M191 Insulation Tester Calibrator________________________________________ MEATEST, s. this way the calibrator can simulate the above mentioned parameters. S Short current easuring The function allows measuring short current supplied UUT when the output terminals are shorted. 4 1 3 2 Fig
