Product Description
A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). ... Digital multimeters combine the testing capabilities of single-task meters—the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms).
 Homeowners can use this tool to test batteries, check extension cords, and determine why a certain light switch isn’t working. This can save customers hundreds of dollars in the long run because they’ll be able to diagnose and repair the problem on their own instead of paying an electrician to do so.
