AC0606 voltage and current calibration

1. The power supply of the equipment is normal, the measured current passes through the transformer coil, and the municipal power is connected to the voltage acquisition port. 

2. The current is preferably about 80% of the measuring range of the transformer coil, and the load to be measured can also be used for calibration. 

3. After the equipment communication is connected, open the modbus poll project for calibration.

4. Use the instrument to measure the voltage of the voltage acquisition port and the current through the transformer, and fill in the [standard source] project. 

4. After filling in the standard source, wait for 5S after filling in the calibration mode [171], observe whether the values of each voltage, current and power channel are correct, and if correct, the calibration is completed.

5. After the equipment is powered on again, adjust the current to observe the linearity of the equipment, if the power factor is less than 0.5 or negative reverse connection transformer.
