This is essential when you're wiring a house. This is used to determine if you have damage to the insulation on non-energized wiring. This is one of two tests you must perform before hooking up to the meter to ensure the wiring that was run is indeed safe to energize.This tests to see the quality of the insulation on the wire, and to ensure there's no damage or defect that allows current to leak between the leads. This damage commonly occurs in new construction because the carpenters came back through to correct something after the wire is installed, or the drywallers pay no attention to the underlying wiring and they drive a fastener through your wiring. This also occurs when pulling wires in old construction and the insulation becomes damaged by unseen hazards inside the walls.You test the insulation integrity with this meter, searching for leakage between the conductors in the wiring. This test goes hand-in-hand with continuity testing to make sure no damage happened to the conductors during installation.This meter works well, and is of a good size, it comes with terrible instructions, which is par for the course, but they are clear enough to understand the testing modes, and you can go online for instructions on how to properly perform the tests.The display is easy to read, and the testing results are clear. All in all, for the price it's worth it for the advanced home-gamer who is willing to do their own electrical work.
