A fuse tester is a device used to test the continuity of a fuse. It is typically a small, handheld device with a probe on one end and a display on the other. To use a fuse tester, simply touch the probe to each end of the fuse. If the fuse is good, the display will light up or beep. If the fuse is blown, the display will remain dark or silent.
Fuse testers are an important tool for any electrician or do-it-yourselfer. They can help you quickly and easily identify blown fuses, which can save you time and money. Fuse testers are also relatively inexpensive, so there is no reason not to have one in your toolbox.
