Model M151 is a stable high current calibrator up to 120 A. Basic accuracy is 0.035 %. Instrument can be controlled via RS232 or GPIB interface. Calibrator can work in a simulated amplifier mode to increase current ranges of any multifunction calibrator. It is suitable for power meter’s calibration because M151 can be synchronized with the input signal not only in amplitude but also in frequency and phase. Current terminals are isolated up to 450 Vpk against case (protective earth).
M151 is a sophisticated instrument with its own recalibration procedure. The procedure enables to adjust any deviation directly from the front panel.
Calibrator is designed for checking parameters of amp meters. With current coil it can be used for calibration of clamp meters.
