The CM420, single wire constant monitor continuously checks two operators wrist straps and a workstation ground and alarms if there is a fault. Continuously verifying the integrity of the ground system is critical to an effective ESD protection program and eliminates the time-consuming task of testing wrist straps before each shift. The systems are compatible with most single wire wrist straps. This is the simplest, and most cost-effective way to ensure a wrist strap is continually working. An audible alarm and light will signal a failure.
