Stable high current calibrator with 120 A AC/DC range, built-in multimeter, floating outputs and both real and simulated transconductance amplifier functions.
- High accuracy throughout all ranges
- 8 Vpk floating outputs
- Real and simulated transconductance amplifiers
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.
