Description

The patented* Desco Dual-Wire Dual-Operator
Programmable Monitor monitors two operators and two
ESD work 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 5.3.2.4.4 "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."

Monitor features and components
A. Operator 1 Status LEDs: When the green LED is
illuminated, operator 1 is properly grounded. When the LED
is illuminated red or yellow and the alarm sounds, operator 1
is not properly grounded.
B. Worksurface 1 Status LEDs: When the green LED is
illuminated, worksurface 1 is properly grounded. When the
red LED is illuminated and the alarm sounds, worksurface 1
is not properly grounded.
C. Operator 2 Status LEDs: When the green LED is
illuminated, operator 2 is properly grounded. When the LED
is illuminated red or yellow and the alarm sounds, operator 2
is not properly grounded.
D. Worksurface 2 Status LEDs: When the green LED is
illuminated, worksurface 2 is properly grounded. When the
LED is illuminated red and the alarm sounds, worksurface 2
is not properly grounded.
E. Power Jack: Connect to the included 12VDC power
adapter.
