WORK SURFACE CHANNEL
The Multi-Mount Continuous Monitor monitoring circuitry is
sufficiently sensitive to detect extremely low current when
used with a worksurface with a conductive layer.
Specifications
:
Test range of monitored circuit 500K - 10M ohms†
Operating Voltage
120 VAC, 50/60 Hz
220 VAC, 50/60 Hz
Work Surface Range
10 Megohms
Wrist strap open circuit voltage 1.2 volts peak to peak @
1-2 MicroAmps
Mat test open circuit voltage
5 to 7.5 volts
Response time to alarm
<50 ms
Operating Temperature
0 - 40°C
Size
3.86"L x 2.10"W x .910"H
† 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.
Figure 5. Using the Multi-Mount Continuous Monitor
Note: Work surface 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.

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

.
Maintenance and Calibration
The Multi-Mount Continuous Monitor is solid state and
designed to be maintenance free. The
/
calibrated to NIST traceable standards. There are no user
adjustments neccesary. Because of the wave distortion
sensing nature of the test circuit, special equipment is
required for calibration. We recommend that calibration
be performed using the Desco
Monitor Calibration Unit. The Calibration Unit is a most
important product which allows the customer to perform
NIST traceable calibration on continuous monitors. The
is designed to be used on the shop floor at the
workstation, virtually eliminating downtime, verifying that
the continuous monitor is operating within tolerances. Per
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.”
