GF312V2 Portable Three Phase Multifunction Energy Meter Calibrator¹

Product Description Product DescriptionGF312V2 portable three phase multifunction watt-hour meter calibrator on-site is the newest product produced by our company by widely visiting users and referring to the advantages of the same kind of products home and abroad. The measured part of the product adopts high speed A/D transmission to send DSP to conduct digital processing, which largely improves measured degree of accuracy and stability. Central processing part adopts 32-bit ARM embedded technology to make instrument interface novel, function abundant, operation distinct and easy, and performance steady. Class of accuracy: Class 0.02, 0.05 or 0.1, range from 12A/600V or 120A/600V, with comfort design, small size and light weight. The model GF312V2 watt-hour meter calibrator is suit for electric power departments, measuring and quality examining departments and electric lab to field use. Our AdvantagesFEATURESScreen capture function;7 inch color TFT touch LCD;Self adjusted clamp-on CTs;Accuracy class: 0.05%, 0.1%;Measurement for energy register;RS232 port for PC software control;Measurement of energy meter errors;USB and RS232 communication ports;Measurement of clock error of energy meter);Large capacity storage device for mass memory;Measurement of turn ratio & phase error for CT;Measurement voltage & current of harmonics of 2nd to 63st;Power supply (lithium battery) / 85-265V AC / U1Un (40-450V);Check wiring failures and calculation of electricity compensation;Measurement of U, I, P, Q, S, phase angle, power factor, frequency etc;Input two pulse signal for master and slave meter synchronously calibration; APPLICATIONPower plant;Electrical laboratory;Energy meter factory;Metrological service center;Power engineering company;Distribution power corporation;Electricity power bureau & power company;National Metrology and testing department;Electrical Department of industrial and mining enterprises; Product ParametersPARAMETERSElectrical parametersAccuracy class0.02%, 0.05%, 0.1%Power SupplyExternal power, 85-265V, 45-65HzPhase voltage supply 40-450V, 45-65HzLi-Battery supplyVoltage measurementRange0-600VError±0.05%(30-600V); ±0.02%(30-600V)Harmonic2nd - 63rdInput impedance range245kΩ@ 250V; 10MΩ @5VStability0.01%/minuteLong term stability<100×10E-6 / YearCurrent measurementRange (direct connection)1mA-12A or 1mA-120ARange (clamp CT)1mA-120AClamp on CTs Optional5A, 20A, 100A, 200A, 500A, 1000A, 2000A, 3000AError (direct connection)±0.05% or ±0.02%Error (clamp CT)±0.2% (1mA-120A )±0.5% (other)Harmonic2nd - 63rdClamp diameter12mm or 18mmInput impedance range0.04Ω@ 0.05A-12AStability0.01%/minuteLong term stability<100×10E-6 / YearPower measure errorActive power (direct connection)±0.05% or ±0.02%Active power (clamp CT)±0.2% (1mA-120A)Reactive power (direct connection)±0.1% or ±0.05%Reactive power (clamp CT)±0.2% (1mA-120A)Stability0.01%/minuteLong term stability<100×10E-6 / YearEnergy measure errorActive energy (direct connection)±0.05% or ±0.02%Active energy (clamp CT)±0.2% (1mA-120A)Reactive energy (direct connection)±0.1% or ±0.05%Reactive energy (clamp CT)±0.2% (5mA-120A)Stability0.01%/minuteLong term stability<100×10E-6 / YearPhase angleRange0°-360°Resolution0.001°Error±0.015°FrequencyRange15Hz-70HzResolution0.0005HzError0.001HzReference MeterMeasuring modes2WA / 2WR / 2WAP3WA / 3WR / 3WAP / 3WRCA / 3WRCB4WA / 4WAb / 4WR / 4WRb /4WAP /4WAPb / 4WRCBrandwidth3000HzSampling16 bit 504 samplers / periodPulse outputEnergy constant25000Pulse ratio1:1Output level5VPulse inputInput channel2Input level3-12VInput frequencyMax. 100HzDisplayResolution800×480LCD7" TFT color touchFunctionVector diagramYesWaveformYesEnergy accumulationYesCT ratio testYesCT PT programmableYesLocal parameter inputYesWiring emulationYesSelf-calibrationYesRecorder checkYesData storageYesGPSYesData storage qty10000External extend memoryYesScreen printingYesCommunication portUSB/RS232 Communication with PCYesUpload dataYesExternal mini printerYesExternal keyboardYesSafetyIP class according to DIN EN 60529IP42Declaration of conformityCE & CNAS conformProtection class according to DIN EN 61140IIOvervoltage category voltage measurementCAT III 600VOvervoltage category currentCAT III 600VStandardlsolation protectionIEC 61010-1:2002Energy measurementIEC 60736; IR46; ANSI C12.20-2002;JJG 597-2005; JJG596-2012; JJG 1085-2013; JJF 68-2019;DL/T 826-2002; DL/T 1478-2015; DL/T 448-2016Reference standardIEC 62052-11IEC62053-21IEC62053-22 & IEC62053-23IEC61010-1:2002Mechanical parametersDimensions (W×H×D) (mm)245 × 168 × 70Weight (kg)1.8Environmental conditionsAmbient temperature-25°C to +50°CStorage temperature-30°C to +65°CRelative humidity30%-95%Power Consumstion≤13VA
