Multi-Meters & Meters
Get to the root of the problem with a multimeter
When an electrical problem arises, there are a number of possible causes. It could be a faulty switch, fuse or wire, but without testing equipment you have no way of knowing what parts need to be repaired or replaced. Having a multimeter on hand lets you test voltage, current and resistance. Once you collect this information, you'll be able to find out the real issue you're facing and address it without wasting spare parts, time or effort.
With the ability to check DC current, you'll be able to test the batteries in smaller electronics. The battery is often the first thing to go when electronics stop working. A digital multimeter will be able to tell you if the battery is the root of the issue or if it's something more serious. You can plan out repairs more efficiently when you're not guessing about where problems in your electronics are originating.
A popular diagnostic tool is the clamp meter. These meters work by clamping an electrical wire between the arms of the device and measuring the output there. They're great for doing final electrical tests during setup, and for finding trouble spots when you're repairing circuits. Get these important tools for any electrician's arsenal and more at Sears.
