TECHNICAL BULLETIN TB-3073 Multi-Mount Monitor Made in the Installation, Operation and Maintenance United States of America Wave Distortion Technology is the Most Reliable Technology for the Continuous Monitoring of Single-Wire (Conductor) Wrist Straps Wave Distortion or vector impedance works by applying a continuous test voltage of 1.2 volts peak-to-peak at 1 to 2 microamperes (0.000002 amperes) to the wrist strap that is connected to the continuous or constant monitor. The test voltage creates a square wave that the monitor circuit compares to established patterns. By monitoring the distortions, or shape of the square wave, Wave Distortion Technology determines if the monitored circuit is complete - the operator is in the circuit and the total equivalent DC resistance is within specifications. Wave Distortion Technology produces a very fast alarm time (<50 milliseconds) and minimal false alarms. ANSI/ESD S20.20 section 7.3 states Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements. Per ANSI/ESD S1.1 Annex A.3 Daily (wrist strap system) testing may be omitted if constant Figure 1. Desco Multi-Mount Monitor monitoring used. Per ESD Handbook ESD TR 20.20 section 5.3.2.4.4 Typical Test programs recommend Description that wrist straps that are used daily should be tested daily. However, if the products that are being produced The Desco Multi-Mount Monitor is a single workstation are of such value that knowledge of a continuous, continuous monitor. It continuously monitors the reliable ground is needed, and then continuous path-to-ground integrity of one operator and one ESD monitoring should be considered or even required. worksurface.
