Everyone should have a Wiggy. It needs no batteries
and it's hard to break.

I might buy one from Amazon. So will this Wiggy really read the voltage
differently than my Fluke? Under what conditions would Wiggy report a
different voltage than a digital multimeter? This comes as quite a
surprise to me that the trusty Fluke would be misleading under certain
conditions.

The Wiggy is a low impedance device that actually puts
a bit of a load on the circuit being tested. It's like
a calibrated electromagnet. The higher the voltage, the
harder the solenoid pulls against the spring and the
farther the indicator moves. The Fluke meter will measure
induced voltages on wiring that has very tiny current
levels. The Wiggy won't react at all unless it's the type
with an indicator light. You could hook some test leads
to an electric hair clipper and get the same reaction.
