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+;
Notice:; - 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- 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 as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashingPackage included: 1 x Digital Volt Amp Meter1 x 50A / 75mV DC Current Shunt
