To Use The Monitor
1. Plug a wrist strap cord banana plug into the
monitored banana jack on the front of the unit. This
automatically activates the selected operator channel.
The red operator LED should turn on.
2. Remove the charges from your body by making
contact with a properly grounded ESD worksurface.
Snap the cord to the wristband, and fit it snugly onto
the wrist. This should silence the audio and cause the
LEDs to switch from red to green. If this does not
happen, check the coil cord for continuity or damage.
Examine the wrist and secure that it has a secure fit.
If you have dry skin, apply an approved dissipative
hand lotion such as Menda 35666
Reztore ESD
Hand Lotion. When leaving the area, a person
can take the coil cord along or leave it attached to
the monitor in park position. Alarm will shut off in
approximately 8 seconds when operator grounding
cord is removed from unit or will instantly shut off
when cord is parked.
Note:
It is recommended that you use the Park Snap
rather than continuously removing the Banana
Plug from its jack. If your process requires the
constant insertion and removal of the Banana
Plug, please contact your Desco Representative
for alternate solutions.

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.
* Contact factory for special limits.
Note: Worksurface must have a conductive layer such
as Dual Layer Rubber or Dissipative 3-Layer
Vinyl or Micastat Dissipative Laminate with
conductive buried layers. Desco Continuous
Monitors are not recommended for use with
homogeneous matting.
Maintenance and Calibration
The Jewel Workstation Continuous Mini Monitor is
solid state and designed to be maintenance free. It
is calibrated to NIST traceable standards. There are
no user adjustments necessary. Because of the wave
distortion impedance sensing nature of the test circuit,
special equipment is required for calibration. We recom-
mend that calibration be performed annually using the
Desco
98220 Continuous Monitor Calibration Unit. The
Calibration Unit is a most important product which al-
lows the customer to perform NIST traceable calibration
on continuous monitors. The
98220 is designed to be
used on the shop floor at the workstation, virtually elimi-
nating downtime, verifying that the continuous monitor
is operating within tolerances. The
98220 provides a
simple and quick means to assure compliance verifica-

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 Customer Service at 909-627-8178 (Chino, CA)
or 781-821-8370 (Canton, MA) for Return Material
Authorization (RMA) and proper shipping instructions
and address. 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, Desco will quote repair
charges necessary to bring your unit up to factory
standards. Call Customer Service at 909-627-8178
