Applications:Suitable for automotive/electric for cars/motorcycles battery monitoring or other products voltage current measurement
Wiring: Black line (thin): vacant or for 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 for 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 .
