Zero Volt Monitor

Desco 19668 is a dual workstation continuous monitor. It continuously monitors the path-to-ground integrity of two operators and two ESD worksurfaces. It also will indicate if voltage greater than ±1.25 V is induced onto the operator. Audio and visual alarms activate in failure situations. The Desco Zero Volt Monitor provides stable continuous monitoring of the path-to-ground and presence of two 1 megohm resistors of an operator’s dual-wire wrist strap. Audio and visual alarms activate (in less than 500 milliseconds) when the wrist strap connection points are intermittent. The Desco Zero Volt Monitor also monitors for a worksurface path-to-ground less than 3.5 megohms. All Desco Zero Volt Monitors are calibrated to NIST standards and include a certificate. A calibration unit is available to preform compliance verification at the workbench without taking the monitor out of service.

• Monitors the path-to-ground integrity of two operators and two ESD worksurfaces independently
• Places dual test signals onto each of the dual-wire wrist strap’s conductors to negate finger-tip voltage and the risk of electrical overstress
• Identifies failures and intermittencies that inferior technologies miss
• Made in the United States of America
