Multifunction calibrator M142i is calibrator of electric quantities for application in calibration laboratories and in production lines where meters are manufatured. It can be used for calibration and adjustment of meters from the field of voltage and current. M142i is economy version of M142 model and contains only voltage and current outputs.

M142i multifunction calibrator is available in bench-top and in 19" rack housings.

Basic parameters

Basic function of the calibrator is generating of the calibrated DC/AC voltage in the range from 0 V to 1000 V and DC/AC current in the range from 0 A to 30 A . Using a 50-turn coil the current range can be extended to 1500 A. The best accuracy of the calibrator on DC voltage ranges is 15 ppm, on AC voltage ranges 250 ppm, on DC current ranges 130 ppm and on AC current ranges 550 ppm. Maximum frequency range is from 20 Hz to 100 kHz for harmonic output waveform.

For calibrations of the thermometers and temperature regulators, the function of simulation of temperature sensors is determined. Calibrator is able to simulate all common used TC sensors of the R, S, B, J, T, E, K and N types as well. Compensation of the TC cold junction is made either by entering value from the keyboard. The precision of the simulated resistance and TC sensors depends on set value and type of the sensor.

User comfort

M142 Calibrator is equipped with a number of other functions which make its use easier. Among them belong possibility to set relative deviations from the actual value of the selected output signal, displaying of the output signal uncertainty, internal calibration procedure and others. Concept of the calibrator's control and indication uses a large area luminescence display on which all necessary information is concentrated. The control is perform by selection from the menu. Moreover, frequently used functions have firmly assigned keys with direct control. The calibrator is equipped with RS232 serial port making it possible to be controlled by personal computer.

The calibrator can be included into MEATEST WinQbase/Caliber software calibration systems.
