It's one name for a system basically consisting of a condenser which can supply a burst of very high voltage, designed to burn off a thin sliver of metal "fuzz" which might be bridging the contacts of the chip detector plug, causing the warning light to come on. The usual advice is that flight may be continued if the warning light goes out.
Systems vary, but some allow a couple of attempts to burn off the chip. If it doesn't work, the chip might be something big enough to have a part number on it! If the light stays on, it's worrying at the best of times, even in VMC; the normal course of action would be to look for an emergency landing area.
