Two leads for straightforward wiring, facilitating connection to automotive/electric vehicle/motorcycle internal circuits. Features reverse polarity protection to prevent burnout from incorrect wiring, with fine-tuning capability.

Function Overview:
1. Range: 4.5-40V (Red) 45-40V (Yellow) 4.5-40V (Green) 4.5-40V (Blue)
2. Supplied with two leads for straightforward wiring, facilitating connection to automotive/electric vehicle/motorcycle internal circuits
3. Features reverse polarity protection to prevent component burnout if leads are reversed, with fine-tuning capability
4. Caution: Input voltage must not exceed 30V, otherwise there is a risk of burnout.
5. Display brightness dims below 5V but measurement accuracy remains unaffected.
6. Displays two decimal places for voltages below 10V; one decimal place for voltages above 10V. This accommodates both battery users' precision requirements and higher voltage measurement needs.
