Possible cause check-up and tests
17.1 Check that the connector of the sensor is
properly plugged into JP1 on the ANL-
T2 board.
17.2 Check that the wires and connector are in
good condition.
17.3 The pressure sensor is defective.
17.4 The pressure measuring circuit on ANL-
T2 board is defective.
18.1 Check that the connector of the sensor is
properly plugged into JP1 on the ANL-
T2 board.
18.2 The system is out of calibration
18.3 The pressure sensor is contaminated with
dirt or is defective.
18.4 The pressure measuring circuit on ANL-
T2 board is defective.
19.1 Check if the wire connected to the
electrode is shorted to ground.
19.2 Check if the electrode is shorted to
ground.
19.3 The electrode is dirty.
19.4 If there is no short to ground then the
