Description
Leading companies use continuous monitors as a cost effective
component in satisfying the paragraph 6.1.3 Compliance
Verification Plan requirements of ANSI/ESD S20.20. The EMIT
Dual Operator Continuous Monitor with Satellites continuously
monitors the grounding integrity of two operators, and two
ESD worksurfaces’ path to ground. The monitor will provide
instantaneous notification of static control equipment failures,
and eliminates the need of costly and difficult to supervise wrist
strap logging record keeping. This unit is highly cost effective
as it is designed to monitor any conventional single-wire wrist
strap and ground cord system.
Per ESD Handbook TR 20.20 paragraph 5.3.2.4.4 Test
Frequency, “Because wrist straps have a finite life, it is
important to develop a test frequency that will guarantee
integrity of the system. 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, then continuous monitoring should be considered or
even required.”
The Dual Operator Continuous Monitor with Satellites is
available in two models.
The Dual Operator Continuous Monitor with Satellites is an
impedance sensing device designed to monitor body types
from a 5th percentile female to a 95th percentile male. This
range covers a 5 foot tall 90 pound person to a 6 foot 5 inch
250 pound person in any production environment.* The
is powered by a 120 VAC, 60/50 Hz, plug-in transformer which
also provides connection to ground.

No user adjustment required: The Continuous Monitor
is drift-free and designed to be insensitive to the effects of
squeezing or stretching the coil cord. It requires no user
adjustment.
The Dual Operator Workstation Continuous Monitor is a
real time instrument that ensures that critical ESD control
components in a sensitive area are effectively grounded. It
independently monitors the operator and the work surface.
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 10 megohms (1 x 10E7 ohms)
exists from the ESD protective work surface(s).
ADVANTAGES OF CONTINUOUS MONITORING
OVER PERIODIC TESTING
Many customers are eliminating periodic touch testing of wrist
straps and are utilizing continuous monitoring to better ensure
that their products were manufactured in an ESD protected
environment. Full time continuous monitoring is superior to
periodic or pulsed testing, and can save a significant amount
of money in testing costs and rejected product. Periodic testing
detects wrist strap failures after ESD susceptible products have
been manufactured. The costs of dealing with the resulting
catastrophic failures or latent defects can be considerable.
Dual Operator Workstation Continuous Monitors eliminate the
need for users to test wrist straps and log the results; by their
function, these monitors satisfy the ISO and ANSI/ESD S20.20
test logging. ANSI/ESD S20.20 Paragraph 6.2.2.2 Personnel
Grounding Guidance states “A log should be maintained which
verifies that personnel have tested their personal grounding
devices.” Per ESD-S1.1 Paragraph 6.1.3 “Daily (wrist strap
system) testing may be omitted if constant monitoring is used.”
WAVE DISTORTION DETECTION TECHNOLOGY
PROVIDES TRUE 100% CONTINUOUS MONITORING
From the technical alternatives available, EMIT designs
and manufactures many of its Continuous Monitor product
offerings using wave distortion technology . Wave distortion
circuitry monitors current/voltage phase shifts and provides
true 100% continuous monitoring. Electrical current will lead
voltage at various points due to the combinations of resistance
and capacitive reactance. By monitoring these “distortions”
or phase shifts, the wave distortion Workstation Continuous
Monitor will reliably determine if the circuit is complete.
