If the sensor(s) selected during Film setup are connected properly to the SQM-160,
the Crystal Status LEDs should be illuminated. If not, return to the Film Menu and
set the Sensor Average parameter to the desired sensor(s). See
section 3.5 on
page 3-6 for detailed information on assigning sensors to a film.
If the Crystal Status LED is flashing, the sensor is most likely not properly
connected. A small test crystal, supplied with each oscillator module, can be used
to test sensor connections external to the vacuum chamber. To use the test crystal,
disconnect the oscillator from its 6 in. BNC cable. Attach the test crystal to the
oscillator's feedthrough connector. The Crystal Status LED will remain illuminated
if the external sensor connections are correct.
See section 6.2.2, Troubleshooting Sensors, on page 6-3 for assistance in
troubleshooting sensor problems.
