CALIBRATOR Multi Function Calibrator For AC/DC Voltage Current Thermocouples Power Energy Model MC140 -- AC/DC voltage 1000Vrms, current 20Arms -- Optional 1000A test coil for current transformers -- Power Calibrator to 2400 W (+1.0 to -1.0 PF) -- Built in multimeter -- Deviation control along with measurement uncertainty readout -- 0.003% basic dc accuracy -- 0.025% basic ac accuracy -- 10 step memory and pass fail output -- Supplied with RS232 and IEEE-488 interfaces UKAS/NIST Traceable About the MC140 calibrator The Multifunction Calibrator MC140 functions as a Voltage Calibrator, Current Calibrator, Power Calibrator, Resistance Calibrator, Capacitance Calibrator and a Thermocouple Calibrator. Having very low uncertainties, it is ideal as a standard of these electric quantities in calibration laboratories. It also has the feature of supplying several different waveshapes in additional to the traditional sinusoidal output. This feature makes it ideal for testing meters which are true rms reading or crest factor sensitive. These signals are also suitable for the basic calibration of oscilloscopes. The calibrator has the capability of measuring temperature with TC and RTD temperature sensors. A built-in multimeter can be used independently or in simultaneous operation with the calibrator output. Basic Functions In the Voltage Calibrator mode, the Multifunction Calibrator generates DC/AC voltages up to 1000 V and in the Current Calibrator mode it generates DC/AC currents up to 20 A . Using a 50-turn transformer, the AC current range can be extended 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%. The frequency range is from 20 Hz to 50 kHz. The calibrator can generate periodic non-harmonic signals with a defined crest factor. Such signals can be used to test the sensitivity of multimeters to distorted signals. The Multifunction Calibrator simulates both resistance and capacitance. The resistance range extends to 50 MOhm and the capacitance range is from 1 nF to 50 μF. The precision of both quantities is sufficient for the calibration of commonly used hand-held multimeters. The basic accuracy of the resistance ranges and capacitance ranges is 0.03%, and 0.5% respectively. The resistance calibration may be used with both DC and AC signals up to 1 kHz.
