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. 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 the different rated input current and the output voltage are available.
