使用說明 Directions for use |
1. 當待測電流從傳感器穿過，即可在輸出端測得電壓大小。(注意：錯誤的接線可能導致傳感器損壞)
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. 傳感器的輸出幅度可根據用戶需要進行適當調節(jié)。
Customs can adjustOutput amplitudeof the sensorby needs.
3. 可按用戶需求定制不同額定輸入電流和輸出電壓的傳感器。
Custom design in the different rated input current and the output voltage are available.
