使用說明 ?Directions for use |
1.?當(dāng)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(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.?傳感器的輸出幅度可根據(jù)用戶需要進(jìn)行適當(dāng)調(diào)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 thedifferent ratedinput current and the output voltage are available.
