使用说明 Directions for use

1. 当待测电流从传感器穿过，即可在输出端测得电压大小。(注意：错误的接线可能导致传感器损坏)

When the current will be measured goes through a sensor,the voltage will be measured at the output end.

(Note: The false wiring may result in the damage of the sensor)

2. 传感器的输出幅度可根据用户需要进行适当调节。

Customs can adjustoutput amplitudeof the sensorby 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。

Custom design in thedifferent ratedinput current and the output voltage are available.
