使用說明 Directions for use |
1. 當(dāng)待測(cè)電流從傳感器穿過，即可在輸出端測(cè)得電壓大小。(注意：錯(cuò)誤的接線可能導(dǎo)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. 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.
