4.2 Replace the DIG-T2 board.
5.1 Check that the Atmos.Press parameter
(sec 8.2.17) is set to the correct
atmospheric pressure.
5.2 The sensor is faulty. Replace sensor.
Possible cause check-up and tests
— The voltage reading must be less than
5mV. A higher voltage may indicate
that the ANL-T2 board fastening
screws are loose or that the power
supply grounding cable is loose.
2.1 If the other functions are OK, the display
is probably damaged.
3.1 DIG-T2 board is faulty.
4.1 Keyboard is faulty.
4.2 DIG-T2 board is faulty.
5.1 Check if the displayed value is near the
atmospheric pressure.
5.2 If after setting the Atmos.Press parameter
the displayed value is significantly
different from the atmospheric pressure
there is a problem with the pressure
sensor.
