M191 calibrator is based on programmable 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.
Device is completed with additional electronic circuits allowing calibration not only resistance ranges,
but also calibration of test voltage generated by UUT, short current verifying, 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.
The calibration can be controlled manually using front panel keypad or in remote mode using one of two
types of interfaces GPIB, RS232. The calibrator can easily fit within calibration systems featuring CALIBER
