The Desco 19218 Jewel Workstation Continuous Mini Monitor independently monitors the operator and the worksurface. The instant an operator’s wrist strap or cord fails, the monitor will issue audible and visual alarms alerting the user of the problem. In the same manner, the unit also confirms that a path to ground of less than 500 megohms exists from the ESD worksurface. The Jewel Workstation Continuous Monitor eliminates the need for periodic wrist strap tests and logging. Continuous monitoring is superior to periodic or pulsed testing, and can save a significant amount of money in testing costs and rejected product. Specifications. Test range of monitored circuit: 500 K - 10 M ohms. Worksurface Limit: Set to 500 Megohms ± 20%. Operating Voltage: 24 VAC, 50-60 Hz. Wrist strap open circuit voltage: 1.2 Volts peak to peak @ 1-2 MicroAmps. Mat test open circuit voltage: 5 - 7.5 Volts. Response time to alarm: <50 mS.
