MC143/143i Multifunction calibrator is a cost saving solution for calibration of meters of electric quantities up to 1000 V and 20A. It offers basic accuracy 0.01% in DC voltage needed for calibration of 3½ and 4½ digit multimeters. Resistance function is covered by eight fix resistors in range from 10 Ω to 100 MΩ. The calibrator offers TC temperature sensor simulation. It can be delivered optionally as well with RTD temperature sensor simulator. Thanks to its small dimensions and low weight the calibrator can be easily used for field calibrations.
The calibrator main application field are production lines of panel meters, multimeters, transducers, measuring amplifiers, thermometers, and calibration laboratories where the calibrator can be applied as source of standard value for calibrations, verifications and adjustments of units under test.
Interface RS-232 and optional GPIB interface bus enable automated operation in remote mode offering time saving automatic calibrations. Model MC143/143i is fully compatible with Powertek calibration SW package CALIBER/WinQbase.
