Why a Multimeter Won’t Do:
A typical multimeter measures resistance by applying DC volt-
age to the circuit and measuring voltage drop. Any current in
ground connection, which is a common occurrence in a work-
ing tool, can easily be factored in calculations and cause a
multimeter to produce an unrealistic results, such as negative
or extremely high resistance.
Ground Pro’ patented technology measures ground imped-
ance while completely ignoring noise and currents on the
ground, providing superior accuracy in difficult conditions.

Why EMI?
High-frequency noise (EMI) on a ground affects the operation
of equipment, potentially causing lock-ups and a variety of
other malfunctions. Sensitive components such as magnetic
heads are also susceptible to damage caused by excessive noise
on a ground. To properly control EMI, one must be aware of
the full range of signals present. Ground Pro
high frequency noise in a wide dynamic range—both average
and envelope peak signals. An audio alarm sounds when EMI
exceeds a set level.
