OEM Best Energy Meter Tester Factory – GDDO-20C AC/DC Electric Meter Calibration Device – HV Hipot
OEM Best Energy Meter Tester Factory – GDDO-20C AC/DC Electric Meter Calibration Device – HV Hipot Detail:
General Information
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.
For meter’s part, it takes high precision power frequency AC collector as core technology, which consists of digital signal processor (DSP) and 16-digit high speed analog-digital converter; For signal source, it uses DSP and 16-digit high speed analog-digital converter to form signal source that produces sine wave signal and distortion wave signal.
Features
● Accuracy class of 0.05. When AC voltage, AC current and active power are measured, the device is equipped with a digital/frequency converter (DFC) with a working frequency higher than 60kHz and multiple current ranges, so high accuracy is guaranteed.
● The distortion wave of 2~31 times, number, times and amplitude of harmonics, and phase of harmonic to fundamental wave can be all programmed.
● 6.5-inch color TFT LCD screen, clear and bright display.
● With RS232 communication port.
● With a large capacity non-volatile memory, can store test results of 300 meters under test, support data view and data upload function.
● With good reliability, easy to operate.
