Locate the power source in the circuit. With the power flowing in the circuit, adjust the dial on the multimeter to measure voltage (AC or DC). Then touch the red positive probe on the multimeter to the positive terminal on the power source and the black negative probe on the multimeter ...
How to check fuse resistance with a multimeter In the left photo, the fuse is blown, the multimeter shows OL, which means no continuity or the resistance is higher than can be measured. In the right photo, the fuse is OK, so the multimeter shows 0 Ω or Ohm. Click on the image for...
battery, the multimeter dial should be turned to the “20 volts” setting. But before the multimeter can be used, all surface charge from the battery must be removed to allow for an accurate reading. To do this, the headlights should be turned on for about two minutes and then turned ...
If your power supply does not appear to have any problems after testing it with the multimeter, check all of the power connectors to make sure they are properly plugged into the devices. Warnings Opening your computer may void your warranty. If your computer was put together by someone else,...
How to check DC Voltage with a multimeter Connect the red Test Lead to “VOhmsmA Jack” and the black lead to DC Current Circuit Symbol “COM” jack. Set the “Range Switch” to desired DC V position. If the voltage to be measured is not known then set the Switch to th...
To test a car battery with a multimeter, set your multimeter to 20 DC voltage, which will let you accurately measure a battery that stores between 0 and 20 volts. Do this by turning the knob to 20 on the “DCV” (Direct Current Voltage) range. Sometimes this is denoted by the letter...
Each fuse has two contacts where you have to touch the multimeter’s test probes to get the readings.Check the fuses one by one (Source: Pinterest) Touch the red probe to any of the two contacts and take the reading. The value should be around 12 volts. No need to worry about ...
In this case, you’ll need to have your car looked at and the ignition cylinder replaced. Check Voltage With a Multimeter Checking your battery’s voltage is one of the easiest ways to diagnose a no-start condition. Most vehicles need about 12.6 volts to crank the engine to life; any...
A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. By taking the capacitor's resistance, we can determine whether the capacitor is good or bad. To do this test, We take the ohmmeter and place the probes across the leads of the capacit...
In this tutorial, we're going learn how to use a multimeter! A multimeter is one of the best tools around the shop for testing electronics and circuits!
