M191 Insulation Tester Calibrator is based on 1 TΩ programmable high resistance decade with 10 kV DC compliance, coupled with test voltage meter. This setup allows for calibration of UUT's test voltage, short current verification, timer function verification and calibration of dielectric parameters measurement including polarization index (PI), dielectric absorption ratio (DAR) and polarization ratio (PR).


M191 is designed for thorough calibration of insulation testers, megaohmmeters, HIPOT testers or any other DC high resistance meters and safety testers with test voltage up to 10 kV. With M191's pallete of functions you'll no longer need multiple instruments and complex setups for high voltage calibrations.

RS-232 and GPIB interface allow for remote control of the calibrator and time saving automated calibrations using SW package CALIBER/WinQbase.
