Product Description

GDDO-20C AC/DC Electric Meter Calibration Device

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

1. 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.
2. The distortion wave of 2~31 times, number, times and amplitude of harmonics, and phase of harmonic to fundamental wave can be all programmed.
3. 6.5-inch color TFT LCD screen, clear and bright display.
4. With RS232 communication port.
5. With a large capacity non-volatile memory, can store test results of 300 meters under test, support data view and data upload function.
6. With good reliability, easy to operate.
