Three Phase Energy Meter Portable Tester

2.1 Main functions
Ø Comprehensive error measurement of low voltage device.
Ø Error calibration of energy meter.
Ø Current transformer ratio checking.
Ø Real-time display secondary wiring diagram and 2496 kinds of wrong wiring will be clearly stated.
Ø Display wrong wiring way and offer the correction method.
Ø Calculate primary apparent power.
Ø Measure the following electrical parameters: U, I, P, Q, Φ, F and etc.2.2 Main features
Ø Support U disk to save calibration data.
Ø Two modes for power supply: lithium battery and power supply by cable.
Ø Store all measurement data of 100 meters for later analysis;
Ø Communicate with the PC, convenient to interface with the management system, It can be equipped with energy meter management system software, for paperless office.
Ø High brightness, high definition, and high resolution5.7"(320*240)TFT color LCD display.
Ø Power supply AC 100~380V.
Ø The system uses a high-speed high-precision digital multiplier, to measure all parameters such as active power, voltage, current, frequency, phase etc. and all the parameters are corrected by software.
Ø The instrument has no potentiometer, to completely prevent error change caused by the transport of equipment and other external factors, thus greatly improving system stability and reliability.
Ø Guarantee the accuracy (0.2%,0.3%,0.5%) of electric measurement between the temperature of -20ºC~ +40ºC.
Ø Standard configured with class 0.2 5A clamp(including non-repeatedly opening and closing error, contact error, external magnetic field interference error and angle difference and etc.);
Ø With 100A,500A,1000A clamp to measure the comprehensive error of LV metering device; With 5A clamp to measure the TA ratio.
Ø Provide error correction function, to facilitate error correction (a password required);
Ø Light and good-looking outlook.
