　　Remarks：

　　1. All dimensions are in mm.

　　2. General tolerance ±1mm.

　　使用说明 Directions for use

　　1. 当测量电流按传感器箭头方向时，输出端获得同相电流。

　　When measure current flows according to the direction of the arrowhead, Output terminal gets the same phase current.

　　2. 初级导体温度不应超过 120℃。

　　The primary conductor should be≤120℃.

　　3. 母排完全充满初级穿孔时动态表现(di/dt 和响应时间)为最佳。

　　The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

　　4. 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)

　　5. 可按用户需求定制不同额定输入电流和输出电流的传感器。

　　Custom design in the different rated input current and the output current are available.
