Description:
1. This voltmeter is 0.36 inch in volume, DC 0-100V, 2-wire and 3-wire products are universal. It breaks the conventional voltmeter. It can work directly in 5V, 9V, 12V, 24V circuits without voltage regulation.
2. Equipped with three wiring, easy access to the car/battery car/motorcycle internal line, with reverse connection protection function, wiring will not burn.
3. It can be used to monitor battery voltage and master battery voltage status in time. It can also be used for voltage measurement of other products.
4. Note that the maximum input voltage of line 2 should not exceed 40V, otherwise there is a risk of burnout.

Feature:
The product has good stability and high measuring accuracy.
Standard size is adopted for appearance and easy installation.
Polarity Protection Circuit for Power Supply.

Warm Tips:
1. The voltage range of three-wire is 0-100V, and can also be used as second-wire, but the voltage should be within 40V (many of the peers can only be within 30V).
2. Ultra-low start-up voltage when using two wires, red minimum 2.5V, green minimum 2.7V, blue minimum 3.0V. If conditions permit, the recommended voltage range DC 4V-30V is the best.

Note:
Please allow 1-3mm differs due to manual measurement.
