• Item Type: Battery Power Capacity Indicator Voltmeter
• Operating current: <20mA

Specifications:

• Display: three 0.28" LED digital tube
• Display color: Red and Blue (two-color display)
• Refresh rate: about 300mS / times
• Measure accuracy: 1% (± 1 digit)
• 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
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 4-30V
• 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
