使用说明/Remarks

1.错误的接线可能导致传感器损坏.传感器通电后,当被测电流从传感器箭头方向穿过,即可在输出端测得同相电压值.Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the arrow direction of the sensor, the in-phase voltage value can be measured at the output end.

2.传感器的输出幅度可根据用户需求进行适当的调节.

The output amplitude of the sensor can be adjusted according to the user's needs.

3.可按用户需求定制不同额定输入电流和输出电压的传感器.

Sensors with different rated input current and output voltage can be customized according to user requirements.
