Hand Lotion. When leaving the area, a person can
take the coil cord along or leave it attached to the
monitor in park position.
NOTE: Removing the banana plug from the monitor’s
operator jack will disable the audio alarm.
It is recommended that you use the Park Snap rather
than continuously removing the Banana Plug from its
jack. Doing so will increase the life span of the operator
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
recommend that calibration be performed annually using
the Desco
98220 Continuous Monitor Calibration Unit.
The Calibration Unit is a most important product which
allows 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 eliminating downtime, verifying that the
continuous monitor is operating within tolerances. The
98220 provides a simple and quick means to assure
compliance verificaton Per ANSI/ESD S20.20 Table 3
per ESD TR53.
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

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
