The SCS 770044 Ground Master Monitor is an equipment ground continuous monitor for metal tools. It continuously monitors the path-to-ground impedance and electromagnetic integrity of eight metal ground connections of process tools in work areas - including semiconductors, disk drives, flat panels, and electronic equipment manufacturing environments. The monitor provides both visual and audible alarms and includes fuse protection for each channel.

The 770044 Ground Master Monitor continuously monitors eight metal tools for electromagnetic interference (EMI). EMI can cause equipment lockups and malfunction. The Ground Master Monitor will alarm if EMI is detected. Each one is calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology (NIST) and includes a certificate of calibration. The 770044 also meets the Continuous Monitor requirements of ANSI/ESD S20.20 in accordance with ESD TR53, as well as the recommendations of ESD Handbook ESD TR20.20.
