  • Operating temperature: -10 to 65° c
  • Operating Humidity: 10 to 80% (non-condensing)
  • Working pressure: 80 to 106 kPa
  • 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
Package Includes:
  • 1x Two colour Digital Voltmeter Ammeter Meter
  • NO Retail Box. Packed Safely in Bubble Bag.
