View the ohm reading on the multimeter's display. In most cases, the resistance shown on the display should be more than zero but less than 20. If the multimeter shows "0" on the display, no continuity exists between the two pins. This is usually the result of a damaged wire or solde...
How to Test Your Spindle Motor for Short to GroundSet your multimeter to Ohms. Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a ...
Measuring a fuse on board with an analog multimeter The common type and current rating of a fuse in a Monitor and Power Supply are slow blow 3.15A to 5 Ampere. Here is the part on how to test a fuse. Switch off the power of the equipment, remove the casing and you will see a fus...
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...
Everybody has batteries in many different kinds of devices and sometimes it’s useful to know if the batteries are good of bad. Of course the best way to test it is with a meter but not everybody has a multimeter and you don’t always have one handy. Here is a simple method to tes...
Now that you have determined that a capacitor is possibly bad, you may want to confirm your diagnosis. This can best be done with acapacitor testeror amultimeterthat is capable of capacitance measurement. If you have a basicohm meter,you can check a capacitor; however, it will not tell yo...
2. Connect the digital multimeter to the load cell you want to test. 3. Using the multimeter, check: The value of the resistance between the positive signal wire and the negative signal wire. It must be the same as or similar to that indicated on the load cell data she...
It's good to know how to test a power supply so you know it's working properly. Learn how to do so using a multimeter.
Connect one multimeter lead to the copper tube with an alligator clip and touch the other lead to the nut that connects to the gas valve. The nut must be disconnected from the valve when performing this test. Start the pilot, hold in the gas control to keep the flame lit and check the...
Voltage Test: Testing the PSU With a Multimeter Now it's time to check whether the PSU is supplying adequate power to each pin. You'll need to measure the voltage on 13 pins that fall into three categories: 3.3V, 5V, and 12V.
