Wiring diagram:

 

- The ground wire of power supply end and measuring end of this ammeter adopts common ground design, that is, the ground wire of the power supply and test end is interlinked, so the test end of the ammeter can only be stringed after the household appliance (ie, Between the negative pole of the measuring device and the negative pole of the power supply of the device under test)

- It is recommended that the power supply terminal of the meter head be powered by a single DU isolation.

- The shunt must be connected to the circuit before use and then connected to the digital ammeter to prevent high voltage damage to the meter.
