使用說(shuō)明 ?Directions for use
?
1.?當(dāng)待測(cè)電流從傳感器穿過(guò)，即可在輸出端測(cè)得電壓大小。(注意：錯(cuò)誤的接線(xiàn)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(hù)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 ratedinput current and the output voltage are available.
