This is generally good advice but won't solve the problem of
"ghost voltage" measurements. High input impedance is, for
most purposes, a desirable characteristic in a meter to
keep from loading the circuit under test. However, low
impedance is needed to determine whether a power circuit is
really energized or just capacitively coupled to an
adjoining wire.

True!

This is one job where a relatively
inexpensive electrical tester can outperform an expensive
meter.

Also true!

(I am not talking about the $2.99 Harbor Freight
meter here,

True, and that's a relief! So many posts about that meter/door stop. I
usually pay more than $2.99 for a good set of test leads.

but testers such as Klein's Wiggy, Ideal's
Vol-Con, or Fluke's 7-600.)

Good suggestion.....Mac
