Top 5 Best Uses of Multimeter for your Home

Multimeters are the ultimate solution for all types of electrical work. It includes installing a ceiling fan, changing a junction box, identifying the hot wires, etc. The device can measure 3 essential electrical components, namely voltage, current and resistance. Thus, every DIYer must have a Multimeter or Multimeter Tool Kit. Let us now see the best 5 uses of Multimeter for every home use.

Best 5 Uses of Multimeter for Home:

Test Batteries – You can use a multimeter for testing batteries used for household items like a remote, video game, torch, lamp, etc. Using the multimeter’s voltage modes, the user can find which battery works fine and which not. Users can do it by using the DC voltage setting to touch the probes to the battery terminals. It will help you determine how much of its original voltage the battery supplies.

Check if the power cable is broken – It is done by measuring the resistance between hot and neutral wires of a residential electric cable. If the resistance is infinite or the device shows OL or open loop, the cable is broken.

Check Extension Cords/electrical outlets – To check the household outlet, prefer the 200-volt range device and insert the probes into outlet slots. If you don’t get the reading of around 120 volts, there is a problem with the electrical outlet.

Differentiate old light bulbs – It is done by adjusting the meter dial to continuity test mode. The testing process is done by touching one probe to screw thread and the other to foot on the bottom of the bulb. If the bulb is bad, the open-loop or OL is displayed on the device screen or shown as infinite resistance. The other way is when the probe is touched, the multimeter makes a sound if the bulb is in good condition, while there’s no sound when the bulb is dead.

Identify the hot wire – The user needs to find a power outlet and set the device to the highest point on the AC range. Using a black and red probe, touch each of the wires at the back of the outlet. Thereby the user can determine if the wire is in a hot, neutral or in ground state.

Test a bad/wall switch – Checking a faulty switch using the multimeter is another common device application. It is useful when the light fixture is not working correctly. Testing is done by setting the 200-volt range and placing one probe on the terminal connected to the load and the other on the ground screw. You should get output as 120 volts when the switch is closed and 0 volts when it is open or-else the switch is faulty.


Multimeters are handy measuring tools for primary fault finding and field service work. Also, it is a versatile tool known for a high degree of accuracy. This testing instrument is known for troubleshooting various electrical problems in household devices like electronic equipment, motor controls, domestic appliances, power supplies and wiring systems. So, get the best fit multimeter for your home and solve all your electrical problems quickly and easily.
