The errors, voltage, current, active and reactive power, phase, frequency, and power factor can be measured simultaneously, also vector figure and wiring results will be displayed.
Simultaneously test two detected pulse, and the constant, working mode and number of detected pulses at the same time can be totally different.
GDYM-1A Single phase Electric Energy Meter Calibrator is multi-parameter measuring instrument which is full digital, mullti-function and high precision.
GDDO-20C AC/DC Electric Meter Calibration Device is used to detect basic error of various power frequency electric instruments in power systems, including voltmeter, ammeter, wattmeter, ohmmeter, single phase & three phase AC energy meters (optional) and basic error of DC volt-meter and ammeter.
