M142i Multifunction Calibrator

10 ppm laboratory standard of voltage and current with AC/DC ranges up to 1000 V and 30 A for calibration of multimeters up to 6½ digits.

  • 10 ppm accuracy
  • 30 A range

Multifunction calibrator M142i is calibrator of electric quantities for application in calibration laboratories and in production lines where voltage and current meters are manufactured. Load capacity of the voltage output is 30 mA - enough for most high-consumption analogue meters.

User comfort

M142 calibrator is focused on user friendliness making calibrations simple and straightforward. Each function has its dedicated chunky button and all relevant details including total relative accuracy are shown on large LCD. Range of adapters for easier terminal connection and automation possibilities, relative deviation feature that can help you with UUT error calculation and easy keyboard-controlled adjustment procedure are just a few examples to prove the point.
GPIB and RS-232 interfaces are present in both versions so the calibrator can be operated via remote control or used in WinQbase/Caliber software calibration systems including the CamOCR module for automated optical UUT readouts.
