What is involved in a continuous monitoring meter?
These devices are mains powered and usually form part of the gear employed in a workstation as to satisfy ESD standards and their intention is to continuously monitor the ground paths for the workstation and/or individuals, should the operator’s ground cord fail whilst connected to the monitor and/or the surface where installed onto, it will raise audible and visual LED alarm indications, the idea is not having to implement scheduled/periodic managed tests, the unit usually just snaps into a couple of 10mm sockets attached to the work surface, the monitor uses the AC ground as test reference. There are a few technologies available to apply eg double wire provisioning and wave distortion monitoring. The pulse testing monitoring method is sometimes applied onto double wiring but is considered not to be fully compliant with international standards as a current pulse is sent around the loop covering only part of the time and there may be ESD discharges in between pulses, standards specify
