Description

A.C. Power Meter (Bench-Top)-- True RMS V, A, W.

The GPM-8212 is a bench-top power meter suitable for middle- to high-end application. Performance and functionality are maintained at the highest level as in maximum 9999 CT/PT ratio, high immunity to external noise, and true RMS voltage/current/power. Extra attention is paid to simplify setup and operation. The large 0.56" display shows all three units, Wattage/Voltage/Current, either in PF or Hz, simultaneously. PC connection through RS-232C or RS-485 interface adds automatic calibration feature providing minimum error factor and data/control interface for automated test systems.

Features:

     Simultaneous Display of W, A, V ( PF or Hz )

     True RMS V, A, W

     Auto Calibration Via Computer

     Max. / Min. / Hold Function

     High Immunity to External Noise

     CT Ratio (1 ~ 9999)

     PT Ratio (1 ~ 9999)
