Sensor Incompatible

This error message means that the sensor board software is not supported by the main
board software. Either the sensor board or the main board software is too old.
Replace the main board with one compatible with the sensor board. Call the factory for
assistance. You will be asked for main and sensor board revision numbers. To read the
main board revision, press DIAG and scroll down until Inst SW Ver is showing. To view
the software board revision, press DIAG, choose the appropriate sensor, and scroll down
until Board SW Ver is showing. The main board can be replaced only at the factory.
Instruction Manual
Cycle the power off and then on.
If cycling the power does not help, call the factory.
The main board must be replaced. To do this, you must return the transmitter to the
factory.
If cycling the power does not help and the fault message was Main Board User
Data, reset the analyzer to factory default, re-enter user settings, and repeat
calibration.
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.
If the ribbon cable is properly seated and appears undamaged, replace the sensor
board.
