It is recomended to use SET (software tool)for setting of the sensor
type module. For all IQ2 series controllers with firmware version 2.1
or greater, or IQ3 series controllers, the SET Unique Sensor Reference
should be used:

Alternatively set scaling mode to 5 (characterise) and enter scaling
manually as defined in the table opposite. Note that for IQ3 the scaling
mode and exponent do not need to be set up.

For all other IQ controllers see Sensor Scaling Reference Card
TB100521A.
