Controls And Indicators - 3M CTM051 User Manual

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.
