Calibration
Equipment Required
For this test, the Wrist Strap and Ground Monitor should
be disconnected from the monitored ground.
Use the SCS CTE701 Workstation Monitor Checker.
Connect the ground input of the checker to the ground
terminal of the Wrist Strap and Ground Monitor. Set
the checker to a proper resistance alarm level (see user
guide
). Connect the red tip of the checker
to the GND1 terminal. Press the Fail button on the
checker. The red LED of the corresponding ground of
the monitor should remain on. Press the Pass button
on the checker – the corresponding light on the monitor
should be green.
The checker verifies the proper operation of dual wrist
strap monitoring. Connect a 3.5 mm test cable to both
the checker and to the operator jack of the monitor. At
this point the monitor should indicate failure. Depress
the Pass button on the wrist strap section. The monitor
should indicate a good connection. While pressing the
Pass button, press body voltage “high.” At this point the
Wrist Strap LED would be blinking red.
