Product precautions information
1 The unit is must carefully handled when transportation, operation and storage, fall or strong vibration, etc. is not allowed.
2. Signal source shall be added to the bus fault and ground.
3. The calipers of NAZJ6 DC System Earth Fault Detector only work for AC circuit, not DC circuit.
4 When all branches have no grounding, should pay attention to whether the power supply part of the grounding point, such as batteries, chargers and other parts.
