Monitor Calibration Unit
Operation Instructions
Figure 1. Desco
Description
The Desco
simplify the process of calibrating Workstation Continuous
Monitors. The unit allows the user to quickly and easily
verify whether a tester is operating within specifications. The
Monitor Calibration Unit is a passive device and requires no
power source.
“A Compliance Verification Plan shall be established
to ensure the Organization’s fulfillment of the technical
requirements of the ESD Control Program Plan (ANSI/
ESD S20.20-2007 section 7.3). The product qualification
for the Continuous Monitors per ANSI/ESD S20.20-2007
Table 3 is “User defined” test method and required limits,
and compliance verification is per ESD TR53 with the
required limit being “Manufacturer defined.” Per ESD TR53
Compiance Verification “Compliance verification of the
constant monitor device should follow the manufacturer’s
instructions.”

Calibrating the Full Time Continuous Monitor
The Full Time Continuous Monitor is available as following
item number:
TESTING THE OPERATOR CIRCUIT
Step 1: Connect the Calibration Unit’s banana plug wire
labeled “GROUND” to a known ground. Do not plug the
ground lead from the Calibration Unit to the monitor’s
common point ground banana jack. There is a 47 kilohm
resistance to ground.
Step 2: Insert the Calibration Unit’s banana plug labeled
“OPERATOR” into the jack labeled “OPERATOR” on the Full
Time Continuous Monitor (see Figure 2). Power the monitor.
Figure 2. Connecting the OPERATOR test lead from
the Monitor Calibration Unit to the Full Time Continuous
Monitor
Step 3: Start the Calibration Unit’s selector knob at the full
counter-clockwise position. When testing the OPERATOR
circuit, test only the first four limits on the Calibration Unit.
Rotate the selector knob to the “LOW FAIL” position; the
red “OPERATOR GROUND” LED on the monitor should
illuminate and alarm.
