Overview

The 3M

Ground Pro

Ground Integrity Meter measures several important

™

parameters of ground integrity: ground impedance, voltage, and high-frequency noise

(EMI) on a ground.

Ground connectivity is measured in accordance with ANSI 6.1, ANSI/ESDA S.20.20

and other standards. More specifically, it is measured as AC impedance in a way that

is immune to parasitic voltages and currents on a ground.

In addition to monitoring the ground connection, the Ground Pro measures high-

frequency voltage (EMI) on the ground that is often present in a factory environment.

Such interference causes problems with the operation of equipment.

The Ground Pro also measures AC and DC voltage on the ground in case of

miswiring.

General

Power

Ground Pro uses a 9V alkaline battery. Do not use any other battery. If you are not

using your Ground Pro for an extended period of time, remove the battery from the

unit in order to prevent damage caused by a possible battery leakage.

Note: Not all batteries labeled similarly have the same performance. Often an off-

brand alkaline battery has only 50% to 60% of the capacity of the leading brand-name

battery.

Installing the Battery

Slide off the battery door at the back of the Ground Pro and attach the 9V battery to

the battery clips. Observe the polarity of the battery. Re-install the battery door.
