M-141 Portable Multifunction Calibrator
Multifunction calibrator is designed for use in
calibration laboratories, quality departments and production lines
as a standard for electric quantity meters testing.
With model M-141 calibration of voltmeters to 750 V, ammeters to 2 A,
resistance ranges of multimeters and industrial evaluation units
can be performed easily. Interface RS-232 enables to add the
calibrator to the automated calibration and testing systems.
Model M-141 can work under Meatest application SW like WinQbase
and Caliber. Version M-141R contains build-in programmable RTD simulator for simulation of
Pt/Ni temperature sensors.
