5 Things You Can Do With a Multimeter
A multimeter is a useful tool for every homeowner. It’s a handheld device that can run a quick check of your circuits, components, and devices. This handy gadget can help you take care of many DIY projects around your house.
What Can a Multimeter Do for You?
A multimeter can replace three separate meters. You can use it:
- As a voltmeter to measure the amount of AC or DC voltage in a circuit.
- As an ohmmeter to find the level of resistance in a circuit.
- As an ammeter to measure the current flowing through a closed circuit.
What Type of Multimeter Should You Get?
Multimeters come in digital or analog formats. Which one is best for you?
Analog multimeters are inexpensive and easy to use. They are not as accurate at reading voltage levels as digital multimeters are, but they are excellent at reading voltage changes and current flow.
Digital multimeters provide readings on LCD screens, which many people find easy to read. They are extremely accurate at reading voltages. Depending on the features you get, a digital multimeter can be pricey compared to an analog one.
Buying and Using a Multimeter
Multimeters are available in most hardware and home improvement stores. When you go shopping for one, you’ll see them in prices ranging from $20 to $1000. There’s no need to spring for an expensive multimeter unless you’re planning to turn professional. For home DIY purposes, a cheap one is fine.
There’s a learning curve for any tool. You will have to get used to the buttons and symbols on your multimeter, but this won’t take long. Most multimeters come with two insulated, color-coded probes. You simply connect them to the right ports, terminals or jacks on the device you’re testing.
Five Things You Can Do With a Multimeter
Are you ready to try out your multimeter? Try these five tasks.
1. Test Your Batteries
Use the voltage meter to check your battery’s output. To do this, plug the multimeter’s probes into the battery’s jacks. Most multimeters have colored probes to make this easy. You’ll get a clear reading of the battery’s remaining voltage.
2. Check Your Extension Cords
Use your multimeter’s ohm setting to check your extension cords. This will show whether the cord is safe to use. The resistance level should be .8 ohms or lower. If your extension cords show high resistance, don’t use them.
3. Test Your Outlets
An outlet that’s working properly should emit 110 to 120 volts. When you check the outlet, you should check both the hot wires and the neutral wires. If you get different readings, you have a faulty outlet and should consult an electrician.
4. Check the Temperature
Your multimeter can measure the temperature of components, liquids, and gels. If you need to take temperatures while you’re working, you can do it with your handy multimeter. Most will measure temperatures in both Celsius and Fahrenheit.
5. Check Your Light Bulbs
Your multimeter can help you detect life in old light bulbs. This is especially handy for checking bulbs on an old string of holiday lights. To check each bulb, set your meter to continuity test mode and touch the probe to the bottom of the light bulb. This will only work on incandescent light bulbs.
Put Safety First
Always use caution when doing any type of electrical work. A multimeter can help you take care of small repairs, but serious electrical problems require serious help. Don’t risk your safety by trying to tackle a job that’s better left to a professional.
