M191 High resistance decade - Insulation tester calibrator Meatest


  • Total resistance range 10.00 kΩ to 1000.0 GΩ
  • Resistance accuracy 0.1 to 5 %
  • Test voltage range 10 000 VDC + 5%
  • Test voltage accuracy indication 0.5 % + 10 V
  • Test current indication 4 digit from 0.01 pA to 99.99 mADC
  • Programmable high resistance decade box
  • Short current verification
  • Dielectric and absorption parameters simulation
  • High voltage capacitance in three fix points 10, 50, 100 nF
  • HIPOT timer verification 


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 software support.
