The CM5000 single wire constant monitors eliminate the need to test wrist straps and reduce ESD damage from broken wrist straps that go unnoticed. The CM5000 can monitor two operators and two work surfaces. The unit includes a control unit and two satellite remote monitors that feature a park snap that provides means for operator to disconnect wrist strap cord when normally leaving the workstation without audible (false) alarm sound. The system is compatible with most single wire wrist straps. Reliable, Repeatable Results Accuracy and reliability are improved with the design incorporated into our constant monitors. Phase shifts in the current/voltage are monitored which provide true 100% continuous monitoring. False alarms disappear and adjustments are not necessary with this Wave Distortion Technology. Powered and grounded by an AC adapter, the system is fully automatic and begins sensing when a coil cord is plugged into the unit. A green light indicates a safe connection and a red light and audible alarm communi-cate an unsafe connection.
