M191 Insulation tester calibrator is a device designed for application field of calibration of
insulation testers. It can be used for calibration of any DC high resistance meter with
working voltage up to 10 kV.
M191 calibrator is based on programmable high resistance decade which is completed with additional electronic
circuits allowing calibration not only resistance ranges, but also calibration of test voltage generated by UUT, testing
of short current, verifying of functions of measuring dielectric parameters like polarization index (PI), dielectric
absorption ratio (DAR) and polarization ratio (PR). The calibrator enables also verification of timer function of
UUTs.
Basic feature of the calibrator is adjustable high resistance decade in summary range from 10 kΩ to 1 TΩ. The
decade is designed for operation voltages up to 10 kV. In this range it offers basic accuracy 0.1% to 5 % depending
on set resistance value.
The calibration can be controlled manually using front panel keypad or in remote mode using one of two types of
interfaces GPIB, RS-232. The calibrator can easily fit within calibration systems featuring CALIBER software
support.
