alarm continuously until you either park the cord, or remove the
cord from the operator jack. In the case of removing the cord
from the jack, the audio alarm will only sound for approximately
eight seconds.
Whenever the coil cord is accidentally withdrawn from the jack,
or if continuity from the user to the satellite remote unit is not
maintained, the alarm sounds, the green Operator LED turns
off and the red Operator LED turns on.
Work Surface Channel
sufficiently sensitive to detect extremely low current, allowing
it to be used with mats having a resistance of up to 1x 10E7
ohms (10 megohms). If user desire not to monitor worksurface,
mat circuit can be bypassed with switch, located at the rear of
the satellite.
When the monitor is connected to a static dissipative work
surface, the amount of current that flows is a function of the
total resistance between the monitor and through the work
surface to ground. When the resistance of the work surface
is below a present threshold, the monitor will indicate good.
Conversely, if the resistance level is high when compared
to the monitor’s reference, the unit will alarm. This is an
integrating resistance measuring circuit. Therefore, it is
relatively insensitive to externally induced electromagnetic
fields. The resistance threshold is factory set to 10 megohms
(1 x 10E7 ohms). Custom worksurface range available upon
request. Call for details.
Note: Per ESD S6.1, Grounding paragraph 4.1.1 “Every
element to be grounded at an ESD protected station shall
be connected to the same common point ground.” The
ESD control plan should include a tailoring** statement
that continuous monitors are used and that consistent with
manufacturer’s design grounding is via AC adapter cord to
equipment ground.

Limited Warranty
Desco expressly warrants that for a period of one (1) year from the
date of purchase Desco Continuous Monitors will be free of defects in
material (parts) and workmanship (labor). Within the warranty period,
a credit for purchase of replacement Desco Continuous Monitors, or, at
Desco’s option, the Continuous Monitor will be repaired or replaced free
of charge. If product credit is issued, the amount will be calculated by
multiplying the unused portion of the expected one year life times the
original unit purchase price. Call our Customer Service Department at
909-627-8178 (Chino, CA) or 781-821-8370 (Canton, MA) for a Return
Material Authorization (RMA) and proper shipping instructions and
address. Please include a copy of your original packing slip, invoice,
or other proof of date of purchase. Any unit under warranty should be
shipped prepaid to the Desco factory. Warranty replacements will take
approximately two weeks.
If your unit is out of warranty, call our Customer Service Department at
909-627-8178 (Chino, CA) or 781-821-8370 (Canton, MA) for a Return
Material Authorization (RMA) and proper shipping instructions and
address. Desco will quote repair charges necessary to bring your unit up
to factory standards.
Warranty Exclusions
THE FOREGOING EXPRESS WARRANTY IS MADE IN LIEU OF
ALL OTHER PRODUCT WARRANTIES, EXPRESSED AND IMPLIED,
INCLUDING MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE WHICH ARE SPECIFICALLY DISCLAIMED. The express
warranty will not apply to defects or damage due to accidents, neglect,
misuse, alterations, operator error, or failure to properly maintain, clean
or repair products.
Limit of Liability
In no event will Desco or any seller be responsible or liable for any injury,
loss or damage, direct or consequential, arising out of the use of or
the inability to use the product. Before using, users shall determine the
suitability of the product for their intended use, and users assume all risk
and liability whatsoever in connection therewith.
Maintenance and Calibration
The Dual Operator Workstation Continuous Monitor is solid
state and designed to be maintenance free. The 19232 and
19233 are calibrated to NIST traceable standards. There
are no user adjustments that can be made. Because of
the impedance sensing nature of the test circuit, special
equipment is required for calibration. We recommend using the
Desco 98220 Continuous Monitor Calibration Unit whenever
calibration is performed annually or any of the satellite remotes
are replaced. The Calibration Unit is a most important
product which allows the customer to perform NIST traceable
calibration on continuous monitors and can be used to fulfill
ANSI/ESD S20.20 Paragraph 6.2.2.2 Personnel Grounding
Guidance, “Personnel should check constant monitoring
devices (when used) to ensure that they are functional and
operating before ESDS products are handled. In addition,
constant monitoring devices should be functionally checked
periodically to ensure that they are operating as designed.”
The Desco 98220 is designed to be used on the shop floor at
the workstation, virtually eliminating downtime, verifying that
the continuous monitor is operating within tolerances.
This cannot be verified with standard DC test equipment. The
continuous monitor is an impedance sensing device and the limits
are determined by the magnitude and angle of the impedance.
