Multifunction calibrator M140i is calibrator, determined mainly as standard of electric quantities in calibration laboratories. It can be used for calibration of electrical quantity meters from the field of voltage and current. Calibrator is simpler and low cost version of model M140.

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 20 A . Using a 50-turn coil the current range can be extended from 50 µA to 1000 A. The best accuracy of the calibrator on DC voltage ranges is 0.0035 %, on AC voltage ranges 0.03 %, on DC current ranges 0.013 % and on AC current ranges 0.055 %. Maximum frequency range is from 20 Hz to 100 kHz for harmonic output waveform. consumption. For calibrations of the thermometers and temperature regulators, the function of simulation of temperature sensors is determined. Calibrator is able to simulate all TC sensors of the R, S, B, J, T, E, K and N types as well. Compensation of the TC cold junction is made by entering value from the keyboard.

User comfort

M140 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. As standard calibrator is equipped with RS-232 serial port making it possible to be controlled by personal computer.

The calibrator can be included into MEATEST�s WinQbase software calibration systems.
