How to Measure Resistance with Multimeter

There are many perks of having a multimeter around the house, and the most significant one is the ability to measure resistance. You can use this function to check the accuracy of a resistor, see if it’s working in the right parameters, or determine a circuit’s condition. The higher the resistance, the lower the current flow.

If you are not familiar with multimeters and don’t know how to measure resistance with them, then you have arrived at the right place. Today we are going to show you how to measure resistance with a multimeter, both analog and digital. Without any further ado, let’s jump right into it.

How to Measure Resistance with an Analog Multimeter

Analog multimeters are excellent for measuring resistance. However, they work differently than digital ones. The first thing that you need to consider is that the meter responds to the current flowing through the component that is being tested. With that said, follow the steps below to measure resistance with an analog multimeter:

  1. Select the item that you want to be measured and plug in the probes into the multimeter’s sockets. The sockets are generally labeled as COM for common and the other where the ohm sign is visible.
  2. The next step is to select the required range. Typically, the multimeter function switch will be labeled with the maximum resistance reading to make it more accurate. You need to pick the one where the estimated value of the resistance will be.
  3. Now, you can go ahead and zero the meter. This is done by placing the two probes together and giving them a short circuit. Following this, you can adjust the zero control to have zero ohms reading.
  4. Use the measurement probes on the item to make the measurements.
  5. After getting the readings, you need to turn off the multimeters. It’s always best to turn the function switch to a higher voltage range.

How to Measure Resistance with a Digital Multimeter

It’s more likely that you are using a digital multimeter because the screen makes it easier to get the right readings. Digital multimeters are also faster than analog, and they do not need to be zeroed. Nonetheless, follow the steps below to measure resistance with a digital multimeter:

  1. Pick the item that you want to be measured and insert the probes into the appropriate sockets. Just like the analogue multimeter, the digital version has a variety of required sockets, and they are all labeled.
  2. Turn on the multimeter and choose the maximum resistance reading that fits the estimated value of resistance. Doing this will ensure that you get the most accurate resistance measurement possible.
  3. Perform the measurement and adjust the range if necessary.
  4. After the measurements are done, you can go ahead and turn off the digital multimeter to prevent using up too much battery power.
