V27D two lines DC2.5-30V reversed does not burn, electric motor car digit digital voltmeter

Product Name: V27D two lines DC2.5-30V reversed does not burn, electric motor car digit digital voltmeter
Model: V27D two lines
Color classification:
Product details: V27D two-wire DC voltmeter (DC2.50-30V, there is reversal protection)
Baby Description:

1, the voltage meter wiring simple, just connect the two lines in the table there is reversal protection, reverse does not burn.

2, the voltmeter starting voltage is low, the red just 2.5V able to correctly measure, called the global minimum starting voltage at the same price two line voltage table. This will greatly facilitate the lithium battery, 18650 battery and other users. When voltage is lower than 3.5V, display brightness diminishes, but does not affect the correct measurement.

3, in order to achieve optimum measurement accuracy of the voltmeter to measure the voltage according to different positions to automatically move the decimal point. In measuring the voltage below 10V, display two decimal places; in measuring voltage above 10V, after a decimal point. That is able to meet the needs of the user's battery on the measurement accuracy, but also take into account the need for higher voltage measurements.

4, the voltmeter can be used for motorcycles, cars and other monitoring battery voltage, battery status grasp. Can also be used for other voltage measurement purposes.
