If you know the capacitance per foot of wire, then you can calculate how far it is to the open circuit. To determine the capacitance per foot, take a trip to the hardware store, use a known length of ...

Using a multimeter can be daunting to the uninitiated, but they're not magic. Here's a rundown of the basic functions of the device and what they're used for.

For measuring resonance in circuits, a grid dip meter was also helpful. However, most modern users/operators aren’t accustomed to using that anymore. Report comment ...

For example, a 20 A, 250 V fuse may not be able to clear a fault inside the meter when the meter is across a 480 V circuit. It would take a 20 A, 600 V fuse to clear the fault on that circuit.

For a 45-meter RG-58/U cable, the LED will flash at f1 = 1.67 Hz. When an open circuit is introduced at L2 = 25 meters from the IC, the LED will blink at about f2 = 3 Hz.
