- Set your multimeter to the ohm meter on the selector knob.
- Plug the black probe into the common port.
- Insert the red probe into the jack marked for ohms.
- Gently tap the red and black tips together.
- Your reading should be 0.5 ohms or less.
- If your reading is higher than that, replace the probes.

How do I use a multimeter to check voltage?
- Turn the dial to ṽ. Some digital multimeters (DMMs) also include m ṽ .
- First insert the black lead into the COM jack.
- Next insert the red lead into the VΩ jack.
- Connect the test leads to the circuit: black lead first, red second.
- Read the measurement in the display.
How does a multimeter measure voltage?
Multimeters measure resistance by injecting a small current into the circuit, and then measuring the voltage drop across those points in the circuit. The known current, and the resulting voltage drop are then used to calculate the resistance using Ohm's Law, V=I^2*R.4 Nov 2020

How does a multimeter work inside?
Multimeters measure resistance by injecting a small current into the circuit, and then measuring the voltage drop across those points in the circuit. The known current, and the resulting voltage drop are then used to calculate the resistance using Ohm's Law, V=I^2*R. Then probe the desired area of the circuit.4 Nov 2020
What does a multimeter actually measure?
A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.
Why is a multimeter important to a technician?
The voltmeter, or more often the multimeter, is an incredible tool, capable of troubleshooting nearly every electrical system and fault in existence. No matter how often they are used, and what job they perform, there is always more you can accomplish with knowledge of how they work.8 May 2020
Why technicians still use analog multimeter?
An analog meter still has the advantage of being able to show slow changes very easily; seeing a needle swing up or do is a good deal more intuitive and easy to interpret as opposed to trying to track the changing digits of a digital display.
Why we are using multimeter?
A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. It can also be used to test continuity between two points in an electrical circuit. Multimeters can be used for testing batteries, household wiring, electric motors, and power supplies.
What is the main advantage to using a multimeter a multimeter?
Following are the advantages of digital multimeter : The output can be interfaced with external equipment. They are available in smaller sizes. It can be used for measurement of A.C. and D.C. both quantity. It can be used for measurement of various parameters such as resistance, voltage, current etc.25 Jan 2018
Which brand multimeter is best?
Part of Fortive, Fluke Corporation is the best multimeter brand. Safety is paramount with Fluke. Their devices are well tested and feature very good input protection to shield the meter and user from surges and spikes.
