RTD will have a value, which is depending on the temperature in the
well. The value may vary between 10.000.000 and 16.000.000. If the
value is 16.777.215 and R2 at the same time is below 9.000.000,
there is probably an error with the external reference sensor.
R2 must have a value between 15.000.000 and 16.700.000. If the
value is 16.777.215 or below 15.000.000, there is an error in the
circuit.

Press in the Service Input Menu and the Sensor input
AD-converter Menu will appear.
Shown here are the A/D-converted values for the measurements on
the SENSOR inputs.
The shown values are typical values. The values are only updated for
the inputs that are active.
The values for RTD and RTD ref. apply, when a Pt100 has been
chosen as sensor.
TC must have a value between 8.300.000 and 8.500.000, when the
input is short-circuited.
RTD must have a value between 10.000.000 and 11.000.000, when a
100-ohm resistance is connected to the input.
RTD ref must have a value between 15.000.000 and 16.700.000.
The values for RTD and RTD ref. apply, when a Pt100 has been
chosen as sensor.
mA must have a value between 32.000 and 33.500, when the inputs
are open. At 20mA the value must be between 58.000 and 61.000.
