With this guide, you'll learn the ins and outs of troubleshooting your home and household electronics using a handy multimeter.

To test it, set the multimeter to measure voltage. Insert a probe into each slot and read the line voltage measurement. A properly working outlet gives a reading of 110 to 120 volts.

For circuits that are not powered at the moment, you can remove the fuse from the fuse holder and test the fuse with your meter’s ohmmeter function. You should get a reading when you place your ...

For example, if a circuit required the use of a transistor, ... For demonstration purposes, I decided to use my meter to actually test a 200 K ohm resistor. The resistor tested at 197.6 ohms.

The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable ...

Do not rely on the DMM for protection. Understanding how the meter works to read resistance is also key to safety. Imagine placing a couple of AA batteries across an energized 120V, 240V, or even a ...

Had a Radio Shack continuity tester about 20 years ago. It had a nice feature that latched an LED when continuity was interrupted. Found a ton on intermittent cables with that device, but passed ...
