Applications:Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement

Wiring:

Black line (thin): vacant or buck circuit (module) negative
Red line (thin): power supply+
Black line (thick): COM, common measuring
Red line (thick): PW+, measuring terminal voltage input positive
Yellow line (thick): IN+, current input+
(Please refer to the wiring diagrams for more details)

Notice:

The voltage between the thin red and thin black lines must be within DC 4-30V
The ammeter can only be connected to the negative of the device under test
Exceeds 5A, long-term full load working continuously, it is recommended that the measurement side of the leads are directly soldered to the socket
When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
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
It is unsuitable to use this meter to test current less than 10A .

aPackage included:

3 x Digital Voltmeter Ammeter Meter
3 x Current Shunt
3 x Cable
