SY3640 three phase energy meter field calibrator is a high precious three phase energy reference meter; it uses the advanced technology and latest electronic components available in the world, and use high speed DSP as the main processor to ensure the accuracy and long time stability.
SY3640 three phase energy meter field calibrator is used to calibrate three phase, single phase, active or reactive energy meter under work, and also it can be used as voltage, current and power meter to measure AC parameter of three phase power line.
Functions and Features︰
1. 6.4', 640×480×16(color) dot TFT color LCD, English interface.
2. Measure Voltage\ current\ frequency\ phase angle\power factor\ active power\ reactive power\error of meter.
3. Able to test the single phase meter\3 phase 3 wire meter\3 phase 4 wire meter for both active and reactive at site.
4. Appearance power of 3 phase 3 wire or 3 phase 4 wire.
