   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.

   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.

   In order to maximize precision, the Ground Pro measures impedance down to milliohms and automatically cancels impedance of test leads so that even milliohm values can be read accurately. In addition to measuring ground impedance, the Ground Pro also measures AC and DC voltage on the ground while separately measuring high-frequency voltage (EMI). This information is greatly beneficial when performing diagnostics of equipment malfunctions and lockups. The Ground Pro is an essential tool for anyone concerned with ensuring proper grounding of equipment during installation, maintenance and throughout regular use.

Why a Multimeter Wont Do

   A typical multimeter measures resistance by applying DC voltage to the circuit and measuring voltage drop. Any current in a ground connection, which is a common occurrence in a working tool, can easily be factored into calculations and cause a multimeter to produce an unrealistic result, such as negative or extremely high resistance. The 3M Ground Pro Ground Integrity Meter's patented technology measures ground impedance while completely ignoring noise and currents on the ground, providing superior accuracy in difficult conditions especially in use with a working tool.
