Checking A Ceramic Fuse

To check a ceramic fuse use an ohmmeter or continuity tester.

Checking a ceramic fuse.

The voltmeter suggests the resistance of the fuse. Set your multimeter to ohms lowest range if manual ranging and check the resistance is close to 0 0 ohms. Turn off the power supply to the appliance or other electrical device if the device is hard wired. Put one lead on each end of the.

Turn the meter on and set it to measure continuity. If a continuity tester indicates continuity when you touch its lead to the ends of the fuse it s good. This is necessary for ceramic fuses since they don t develop a blackened appearance like blown glass fuses. How to check a fuse by testing it with a multimeter.

If playback doesn t begin shortly try restarting your device. Multimeters read both volts and ohms. To do this use a voltmeter ohmmeter. Touch one end of the fuse terminal with the black test probe and the other end of the fuse terminal with the red test probe.

Testing a ceramic fuse is the only way to tell if the fuse has blown. Set your multimeter to continuity and check that it beeps when connected to the fuse. Use the testing probes of the voltmeter to test the metallic ends of the fuse. Touch one end of the.

Testing the fuse 1. Turn the equipment off and remove the fuse. If the appliance has a plug unplug the power cord. Turn off the power supply to the appliance or other electrical device if the device is hard wired.

Turn the dial on the multimeter so it points to the continuity. If you want to check a sample fuse from a batch to ensure it will blow when subjected to an overload you ll have to set up a more elaborate test rig. Make sure the device equipment or vehicle is turned off before the fuse. How to test a ceramic fuse step 1.

Set an ohmmeter or multimeter dial to zero. With an ohmmeter or multimeter you should see a reading close to zero ohms if the fuse is intact or infinite if it s blown. If you are using a multimeter. Set an ohmmeter or multimeter dial to zero.
