Volt Meter Display - The voltage between the thin red and thin black
- lines must be within DC 4.5-30V
- The ammeter can only be connected to the negative of the device under test
|
Precautions for Dc Amp Meter - 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
|
Integrated Shunt could use it directly - DC 100V 10A Amp Voltage current volt amp meter tester integrated shunt.
- You dont need to purchase extra shunt

Wiring of Dc Panel Volt Current Meter - 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+
