What is a Multimeter?
A multimeter is a device that can measure the voltage of any battery along with electricity flow (current), resistance, and others.
What is the test for a 12V battery?
If a battery is not putting up with the desired performance it is supposed to deliver, it can be tested with a multimeter. If the multimeter reads less than the potential the battery initially had (e.g.: a 12V battery reads 10V or less than that) then the battery can be termed as damaged.
What voltage should a multimeter be set at?
First, the range of the multimeter should be set at 20V on the DC side. This is an optimum range for measuring batteries within 20V. If the range is less than the voltage of the battery, the meter will display ‘1’.
How to read a black probe?
The reading should be displayed on the multimeter display.
What are the two types of multimeters?
Multimeters can be two types: 1) Digital, 2) Analog. Analog is the one that comes with a scale with a needle pointer. The digital one comes with a digital display and precision knob to control the type of electricity you want to measure under the range (of any of the values a multimeter can measure). The multimeter battery test function allows you …
