M151
Current Calibrator
• Current 8 mA … 120 A
(AC/DC)
• Frequency 15 Hz … 1 kHz
• Best accuracy 0.035 %
• Simulated current and
transconductance amplifier
• Built-in process multimeter
• Output capability 8 Vpk
• RS232, IEEE488 (SCPI)
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.
