Product Description GDDO-20C AC/DC Electric Meter Calibration DeviceGDDO-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. FeaturesAccuracy 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.SpecificationPower frequency AC outputVoltage range (V)50, 100, 200, 400, 600 (800V is optional), Max. output capacity 20VACurrent range (A)0.5, 1, 2.5, 5, 10, 20, Max. output capacity 20VAVoltage adjustment range0~130%, fineness adjustment 5*10Current adjustment range0~130%, fineness adjustment 5*10Accuracy of voltage, current, active power and energy0.05%Accuracy of reactive power and energy0.1%Phase accuracy of current to phase voltage0.05°FrequencyAdjustment range: 45~65Hz,Fineness adjustment: 0.001HzSetting value accuracy: 0.01HzPhase Adjustment range: 0~359.99°Fineness adjustment: 0.01°Setting value accuracy: 0.05°Distortion degree of voltage and current output waveform ≤0.3%Stability of voltage, current and power output≤0.01%/60s (peak-to-peak value)Harmonics2~31 timesAmplitude: 0~20%Phase fineness: 0.01°*N ("N" refers to harmonic order)DC outputVoltage range (V) 0.075, 75, 150, 300, 500, 1000, Max. output capacity 20WCurrent range (A)0.5, 1, 2.5, 5, 10, 20, Max. output capacity 20WAdjustment range of voltage and current 0~120% (not including 1000V), fineness adjustment 5*10Stability of voltage and current output≤0.01%/60s (peak-to-peak value)Accuracy of voltage setting value0.05%Accuracy of current setting value0.1%Accuracy at 75mV output (Load ≥5Ω)0.1%General parametersPower supplySingle phase 220V±10%, 50Hz±5%Use conditions20oC±10oC, ≤85%RHDimension460*460*175mmWeightAbout 20kg
