How to Check Continuity with a Cen Tech Digital Multimeter

Cen Tech digital multimeters are a great tool for checking the continuity of electrical circuits. This blog post will show you how to use one to check the continuity of your circuits.

A digital multimeter is an electronic measuring instrument that combines the functions of a DC voltmeter, AC voltmeter, ammeter, and Ohmmeter into a single unit. These devices are used to measure AC and DC voltage, AC and DC current, resistance, and continuity. A continuity test is used to determine if there is a complete path for current flow.

If you need to test continuity on a electrical circuit, first make sure that the power is turned off. Then use the probes to touch the two points you want to test. If the multimeter beeps or the needle moves, then there is continuity. If there is no sound or movement, then there is no continuity.

What is a digital multimeter?

A digital multimeter is a versatile tool that can be used to measure electrical voltage, current and resistance. It can also be used to test continuity, or the presence of an electrical current, in a circuit. continuity is an important concept in electricity because it allows electrons to flow freely through a conductive material, like a wire. When there is a break in the continuity of a circuit, it prevents electrons from flowing and causes an electrical current to stop.

Digital multimeters are relatively easy to use and are available at most hardware stores. To check continuity with a digital multimeter, you will need to set the meter to the “continuity” setting. Once the meter is set, touch one lead of the meter to one end of the circuit and touch the other lead of the meter to the other end of the circuit. If there is continuity, the meter will beep and/or display a reading on the screen. If there is no continuity, the meter will not beep and/or will not display a reading.

It’s important to note that you should never try to test continuity with live wires because you could be electrocuted. Always make sure that all power sources are turned off before testing for continuity

How to use a digital multimeter to check continuity

A digital multimeter is a handheld tool that measures AC or DC voltage, resistance and continuity. You can use it to test electrical circuits for shorts, grounds and other problems. Many digital multimeters also have a built-in flashlight, which can be handy for checking continuity in dark places.

To use a digital multimeter to check continuity:

1. Set the multimeter to the “continuity” or “resistance” setting.
2. Touch one probe to one end of the circuit and the other probe to the other end of the circuit.
3. If the circuit is complete, the multimeter will beep or display a reading of “0Ω.” If the circuit is not complete, the multimeter will display “OL” (open line) or a high resistance reading.


If the multimeter shows a reading of zero or close to zero, this means that there is continuity and the circuit is complete. If the multimeter shows a reading of infinity, this means there is no continuity and the circuit is not complete.
