Multimeters are devices that combine multiple electrical measurement functions in one unit. These instruments typically measure voltage, electric current and resistance. In order to get the most from a multimeter, you have to understand the readings it gives you.
Sales and Service Engineer Larry Rambeaux demonstrates how to use a voltmeter. He fixes the problem found in an earlier video then repeats the test to verify the fix repaired the problem. Before you can accurately use a multimeter, you have to understand what is being measured and what the measurements should be.
