The patented Desco Dual-Wire Dual-Operator Programmable Monitor monitors two operators and two ESD worksurfaces eliminating the need for periodic testing and record keeping of wrist straps. The Dual-Wire Dual-Operator Programmable Monitor uses low-voltage steady state DC continuous-loop technology to continuously monitor (versus pulsed or intermittent) dual-wire wrist strap functionality.
Independent audio and visual alarm conditions make it easy to identify the status of the worksurfaces and operators. Two operator remotes with 10 foot cables are included for use at adjacent workstations. Each monitor is calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology (NIST) and includes a NIST certificate.
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 monitoring used." Per ESD Handbook ESD TR 20.20 section 188.8.131.52.4 "Typical Test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required."
