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

• 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)

• 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 used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing

• 1 x  Digital Volt Amperemeter (2in1 Digital Tester)
• 1 x  100A/75mV Current Shunt
