The voltage measuring device tests 12 V and 24 V starter batteries. The voltage measuring device checks the condition of the car battery via the battery voltage in the charging cycle, when starting or when idling. The voltage measuring device uses the battery voltage to determine whether the starter battery is still functional. The voltage measuring device also shows the status of the battery in% on the LC display and makes a recommendation as to whether the starter battery should be replaced if necessary.
During the battery test with the voltage measuring device during the starting process of the car, the voltage drop of the battery is measured by the test device. The voltage difference provides information about the condition of the 12V or 24 V battery. In addition to checking the battery, the voltmeter can also test the alternator from the car. All measured values and test results are displayed on the LCD. The voltage measuring device uses Kelvin clamps on 70 cm long measuring leads to measure the battery voltage.
