11.3 TROUBLESHOOTING WHEN A FAULT MESSAGE IS SHOWING
11.3.1 Main Board CPU, Main Board Factory Data, and Main Board User Data Errors.
These error messages mean the main board software is corrupted or the eeprom data on the main board is
corrupted. 
1.    Cycle the power off then on.
2.    If cycling the power does not help, call the factory. The main board must be replaced. To do this, the analyzer
must be returned to the factory.
3.    If cycling the power does not help and the fault message was Main Board User Data, reset the analyzer to 
factory default. See section 7.8. Re-enter user settings and repeat calibration.
11.3.2 Hardware Error.
Hardware error means there is a missing or bad hardware component on the sensor board. The board must be
replaced.
11.3.3 Sensor Board Unknown, Sensor Board HW (Hardware) or SW (Software) Mismatch, or Sensor Board
Not Communicating.
These error messages mean the main board either does not recognize the sensor board or the sensor board and
main board are no longer communicating. 
1.    Verify that the ribbon cable connecting the main board (on the inside of the front panel) and the sensor board    
are properly seated. Inspect the connecting cable for obvious tears or breaks.
2.    If the ribbon cable is properly seated and appears undamaged, the sensor board should be replaced.
