M151 Current Calibrator can generate up to 120 A with one year accuracy ranging from 0.035% to 0.11% at all points. Key signal parameters including selected function, uncertainty and AC signal frequency are shown on large LCD, softkeys under the display are linked to frequently used functions for quick setup.

Calibration domain

The main purpose of M151 is calibration of ammeters or use as a current amplifier but it can be used as well for transducer calibration thanks to its built-in multimeter, as stable current source for contact resistance measurement or as either real or simulated transconductance amplifier.
RS-232 and GPIB interface allow for remote control of the calibrator and time saving automated calibrations using SW package CALIBER/WinQbase.
