Wiring:

Black

wire

(thin): vacant or buck circuit (module) negative

Yellow

wire

(thick): IN+, current input+

(Please refer to the wiring diagrams for more details)

Notice:

1. The voltage between the thin red and thin black lines must be within DC 4-30V.

2. The ammeter can only be connected to the negative of the device under test.

3. Exceeds 5A, long-term full load working continuously, it is recommended that the measurement side of the leads are directly soldered to the socket.

4. When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits.

5. If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing.

6. It is unsuitable to use this meter to test current less than 10A .
