14.4 If the display does not match the
selections on the PT100 simulator then
calibrate the temp. If unsuccessful than
replace the ANL-T2
15.1 Unplug and replug in the connector
making sure good contact is made
15.2 Replace the PT100 sensor
15.3 Calibrate the system. (see para 5)
15.4 Replace ANL-T2 board and calibrate the
system.(see para 5)
16.1 Unplug and replug in the connector
making sure good contact is made
16.2 Fix the connections
16.3 Replace the pressure sensor and calibrate
(see para 5).

Possible cause check-up and tests
14.4 Plug the PT100 simulator into the JP2
connector and try the various temperature
selections.
15.1 Check that the connector of the sensor is
properly plugged into JP2 on the ANL-
T2 board.
15.2 Check the positioning of the PT100 (see
sec 9.20) If the positioning is correct then
the PT100 sensor is faulty.
15.3 The difference in the displayed
temperature when the PT100 simulator is
connected is similar, in magnitude and
direction, to the difference in the
displayed temperature when the PT100
sensor is connected.
15.4 System cannot be calibrated.
16.1 Check that the connector of the sensor is
properly plugged into JP1 on the ANL-
T2 board.
16.2 Check that the wires and connector are in
good condition.
16.3 The pressure sensor is defective.
16.4 The pressure measuring circuit on ANL-
T2 board is defective.
