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 d ifferent rated input current and the output voltage available.
