About the MC140 calibrator

The MC141 Multifunction calibrator is designed for portable and bench use in process control environments, calibration laboratories, quality departments and production lines where electrical instrumentation requires testing and calibration. Calibration of voltmeters to 750V ac/dc, ammeters to 2A ac/dc, resistance ranges of multimeters and industrial transducer units can be performed easily. RS-232 interface enables its use in automated calibration and testing systems. The Model MC141 can work under Powertek SW applications like WinQbase and Caliber.
