On-board voltmeter 34590 is used to prevent battery failures and to check the charging of your car. Through the voltmeter you get permanent information about the status of your battery, which is usually not possible in cars because they lack these status indicators.
Connection via two connection wires: red +/ black - (the voltmeter has reverse polarity protection).
When the voltage is below 10V, there will be 2 digits after the decimal point, which means that the accuracy is 0.01, when it is above 10V, the accuracy is 0.1.
Recommendation: put a 500 mA fuse in front of the voltmeter.
