Meatest multifunction calibrator M142i

The Meatest multifunction calibrator M142i is a calibrator for electrical quantities for application in calibration laboratories and production lines where several meters are produced. The calibrator can be used for the calibration of service meters for voltage and current.

M142i is a cost-effective version of the M142 model and contains only the functions for voltage and current.

The basic function of the Meatest multifunction calibrator M142i is to generate calibrated DC/AC voltages from 0 V to 1000 V DC/AC, and current in the range from 0 to 30 A. With a 50-turn current coil the range can be extended to 1500 A. The best accuracy of the calibrator is 15 ppm at DC voltage. At AC voltage it is 250 ppm, at DC current 130 ppm, and at AC current 550 ppm. The maximum frequency range is from 20 Hz to 100 kHz for harmonic waveforms.

For the calibration of thermometers and temperature controllers the multifunction calibrator M142i is also equipped with a simulation function for temperature sensors. The calibrator can simulate all commonly used TC sensors of the R, S, B, J, T, E, K and N types. The precision of the simulated resistance and TC sensors depends on the value and nature of the sensor.
