Faulty circuit board. Go to the Temperature Input Page and perform
a self test. If the self test fails, then the sensor
input board (if makeup) or the core interface
board (if system) should be replaced.
Faulty temperature sensor. If a successful calibration is not possible,
the temperature sensor is probably faulty, and
the sensor should be replaced.
Poor connection of temperature wires. Excessive resistance from extension cables or
poor connections can lower the temperature
reading. Clean & tighten all connections
to the temperature sensor.
