Demonstration voltmeter. A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. A voltmeter in a circuit diagram is represented by the letter V in a circle.
The problem with using a voltmeter to measure state of charge is that the battery has to be at rest for 24 hours to get an accurate reading. This precludes using the method for day to day operations. When the voltmeter is used without waiting 24 hours a false reading is produced by the surface charge on the plates.
