使用说明/Remarks
1.错误的接线可能导致传感器损坏。传感器通电后，当被测电流从传感器箭头方向穿过，即可在输出端测得同相电流值。
Incorrect wiring may result in damage to the sensor. After the sensor is energized, when the measured current passes through the sensor in the direction of the arrow, the same-phase current value can be measured at the output.
2.在正常工作情况下，有效指示灯处于常亮状态。如果指示灯熄灭，说明电流传感器处于非零磁通状态，如母线电流超过量程等。此时，传感器内部进入扫描状态，输出电流不再与输入电流信号等比例，一旦母线电流回落到量程之内，传感器即恢复正常工作。
Under normal operating conditions, the active indicator is in a constant state. If the indicator is off, it means that the current sensor is in a non-zero flux state, such as the bus current exceeds the range. At this time, the sensor internal scanning state, the output current is no longer proportional to the input current signal, once the bus current back down to within the range, the sensor is back to normal operation.
3.测量电阻是指测量直流电流时。若测量交流电流时，测量电阻降低到70%。R
Measuring resistance is when measuring DC current. If the measurement resistance is reduced to 70% when measuring AC current.
4.原边测量导线或铜棒温度不要超过100℃。
Do not exceed 100°C for the raw edge measuring lead or copper rod.
