Measurement
The RD-31 registers both forward and reverse energy flow and provides voltage, current, power and energy (Active, Reactive, Apparent) information.
Meter and Standard Testing
The RD-31 can be used with a controlled current source to test revenue meters and reference standards. In field applications the RD-31 can perform a true three phase meter accuracy test using existing service load.
Analog Sense
The RD-31’s Optional analog sense feature enables testing transducers and energy meters that provide an analog output between +/- 20 mA.
