M151 Current calibrator is accurate current source up to 120 A. It can be used for calibration of ammeters or as stable current source for precise measurement. The calibrator is equipped with a built-in multimeter that can be used for simulation of programmable transconductance or current amplifier. 

The calibrator includes many other features which facilitate easy use. For example it is currently displayed uncertainty of the output signal, calibration and testing procedures etc. The concept of calibrator control and indication of its status is based on large TFT color display, which provides all necessary information. The calibrator is controlled by opening menus on the display and selection from menus. Frequently used functions are assigned direct-control keys. The calibrator comes with standard IEEE488 bus and RS-232 serial line, which allow the calibrator to be controlled from a PC.

The calibrator is supported in the automated calibration system Caliber.
