The first step of troubleshooting is to check the battery and, try to power on your digital multimeter. If the multimeter doesn’t turn on or the display is dim you may have a weak or dead battery . Simply replace the battery and you should be good to go.
Why is my multimeter not reading current?
If you try to measure the current with a blown fuse, you’ll probably notice that the meter reads ‘0.00’ and that the system doesn’t turn on like it should when you attach the multimeter. This is because the internal fuse is broken and acts as a broken wire or open .
How do you reset a multimeter?
- Set the multimeter to the highest resistance range by turning the dial to the highest “ohm” setting.
- Touch the test probes of your digital multimeter together. ...
- Press the calibration knob until the display reads “0” on the digital multimeter if you don’t see “0 ohms” initially.
How do I know if my multimeter is working?
Place the red probe against the positive terminal of the battery . Touch the black probe to the negative terminal. Ensure that the multimeter provides a reading of 9V or very close to it. Replace your multimeter if it fails any of these tests.
Is multimeter fuse blown?
In case you switch the multimeter to measure voltage, it ‘assumes’ that resistance is very high, that little to no current will be let through. To put it simply, measuring current inappropriately while your multimeter is set to amp function will cause the fuse to blow .
How do I keep my multimeter reading wrong?
To avoid getting inaccurate readings, you need to handle, use, and store meters properly . When you are done using a multimeter, it should always be turned off to extend battery life.
Why is my multimeter reading high?
The first thing to check is that any batteries in the meter are still good . If a weak battery resulted in an internal reference voltage falling, this could cause the meter to read high.
How do I turn on my multimeter?
To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries. Plug the black probe into the COM port on your multimeter . Plug the red probe into the VΩmA port.
How much does it cost to calibrate a multimeter?

How do I test if my multimeter is accurate?
The most accurate reading for a digital meter is in the lowest range that shows the most significant digit in the left-most position . Select the lowest measurement range on the DMM before it over-ranges to read the most accurate results.
How do I use a multimeter to test a battery?
- Make sure the voltmeter on your multimeter is set to 20 DC volts. ...
- Touch the positive (red) meter probe to the positive (red) battery terminal.
- Touch the negative (black) meter probe to the negative (black) battery terminal.
- Ask a friend to turn the headlights on.
How can you tell if a 13a fuse is blown?
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
Can you test a fuse with a multimeter?
To test if the fuse is blown, we require a multimeter . Once configured, a multimeter can measure the resistance of the fuse element. Resistance is measured in Ohms ‘Ω’.
