Electrical Power Calibrator
0 -1000V 0 -50 A AC/DC Single Phase Standard Power Source
Calibrator
This device is used for testing and calibrating all kinds of
ammeter, voltmeter, ohmmeter under 0.2 level.
It can also be used as testing power source, matching with high
level standard meters to calibrate ammeter, voltmeter, ohmmeter at
0.2 or higher level.
There are two regulation modes: analog regulation (potentiometer)
and digital regulation (keyboard).
