Page 4: Controls And Indicators
The 3M Ground Pro Ground Integrity Meter is a comprehensive instrument that ™ measures the ground connection of your equipment in accordance with ANSI 6.1 and ANSI/ESDA S.20.20 standards. In addition to measuring ground impedance, it also measures AC and DC voltage on the ground as well as the presence of high-frequency noise or electromagnetic interference (EMI) on the ground, alerting you to possible functionality problems, such as tool lockups, erratic behavior and parametric errors. - Page 5 Brief Tour of your 3M Ground Pro ™ Ground Integrity Meter Please refer to the rest of this User’s Guide for detailed explanations of each control, indicator and connection.

Page 6: Installing The Battery
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. -
