the monitor has been interrupted. The red light in the Probe Status window and
the O FAIL message indicates a problem with the probe or the sensor crystal.
The Parameter/Status display will show the last display mode selected prior to
removing power from the monitor. See Parameter/Status Display Modes Section
on page 26 for detail description of the Parameter/Status display.
Using the standard 3 meter triaxial cable and connect the Sensor Probe to the
Plating Monitor rear panel connector labeled PROBE A. Be careful not to touch
the surface of the sensor crystal installed in the crystal holder. After the Sensor
Probe has been connected, pressing the STOP button should step Probe Status
Indicator from red to green indicating a good Sensor Probe is connected and is in
active. The O FAIL message then should be clear.
Pressing PLATE or PREPLATE will reset thickness display to zero. Breathe
lightly onto the sensor crystal surface. The displayed thickness should increase
due to condensed water vapor on the crystal. The thickness then will decrease as
additional water vapor evaporates from the crystal surface.
If your monitor is a dual probe model, you may also want to connect a second
Sensor Probe to the monitor connector labeled PROBE B. You will need to make
Probe B the active probe by pressing PROBE B button follow by PLATE button
(Note that Probe A is now in standby). An O FAIL message should flash in the
main display indicating Probe B has been failing. Press STOP key, the O FAIL
message should be clear and the Probe B Status Indicator should change from red
to green. Probe B is now the active probe. Test Probe B the same way you have
tested Probe A.
If everything responds as described above, the total system is OK. The monitor
can now be programmed to suit your application.
