Aug 20, 2024 · The multimeter is connected in series with the circuit to measure current. It uses a shunt resistor to measure the voltage drop across it, which is then converted to a current reading using Ohm’s law. Resistance Measurement: A small known current is passed through the component, and the resulting voltage drop is measured. The resistance is ...

Locate the dial of your multimeter. This has the arc-shaped scales visible through the window and a pointer which will indicate the values read from the scale.[2] X Research source The arc-shaped marks on the meter dial face may be different colors that indicate each scale, so they will have different values. These determine the ranges of magnitude. A wider mirror-like surface shaped like the ...Find the selector switch, or knob. This allows you to change the function between volts, ohms, and amps, and to change the scale (x1, x10, etc.) of the meter. Many functions have multiple ranges, so it's important to have both set correctly, otherwise serious damage to the meter or harm to the operator may result.[3] X Research source Some meters have an "Off" position on this selector switch ...Locate the openings in the case where you'll insert the test leads. Most multimeters have several jacks used for this purpose.[4] X Research source One is usually labeled "COM" or (-), which stands for for common. This is where the black test lead will be connected. It will be used for nearly every measurement taken. The other jack or jacks should be labeled "V" (+) and the Omega symbol (an ...Locate the test leads. There should be two test leads or probes. Generally, one is black and the other red. These are used to connect to whatever device you're planning on testing and measuring.Find the battery and fuse compartment. This is usually found on the back, but is also sometimes on the side of some models. This holds the fuse (and possibly a spare), and the battery that supplies power to the meter for resistance tests. The meter may have more than one battery and they may be of different sizes. A fuse is provided to help protect the meter movement. Likewise, there is often ...Make sure that your multimeter is set to the right setting for the unit that you are measuring otherwise you will not get the correct results or any results. Thanks Helpful 5 Not Helpful 2When you are going to check any part for continuity, you must remove the power. Ohm meters supply their own power from an internal battery. Leaving power on while testing resistance will damage the meter. Thanks Helpful 2 Not Helpful 1If the multimeter stops working, you should conduct some tests like checking the fuse. You can replace these at places like Radio Shack etc. Thanks Helpful 1 Not Helpful 1Respect electricity. If you don't know something, ask questions and ask someone more experienced. Thanks Helpful 19 Not Helpful 11Never connect the meter across a battery or voltage source if it is set to measure current (amps). This is a common way to blow up a meter. Thanks Helpful 0 Not Helpful 0Always check meters on known good voltage sources to verify operational status before using. A broken meter testing for volts will indicate 0 volts, regardless of the amount present. Thanks Helpful 0 Not Helpful 0- 1.9M
Here is a step by step guide on how to use a multimeter to test for voltage: First, figure out whether the application being testing utilizes AC or DC voltage. Afterward, adjust the meter dial to the suitable function to DC Voltage or AC voltage. Adjust the range to the number little higher than the predictive value.
Nov 4, 2020 · Multimeters are used for taking basic electrical measurements related to Ohm’s Law. This includes measurements like voltage, current, resistance, etc. Multimeters can be both handheld or ...

Apr 15, 2023 · To read and measure the ohms resistance using a multimeter: Clip the test leads on the resistor leads. Dial the multimeter to the estimated resistance range. Read the value. If your multimeter gives you a 1, then you’ve guessed low for a value. Move the multimeter’s dial upward until it gives you a valid reading.
