The correction can be performed using a preset tempera­
ture gradient (number
1 in Fig. 6.18 ) or by collecting tem­
perature data from a sensor in runtime (number 2 in
Fig. 6.18 ).
Important
The sensor from which data will be collected for tempera­
ture compensation must be defined as a Temperature
Sensor Type (number
8
in Fig. 6.15).
The Temperature Compensated Value will be calculated
using the Sensor measurement, minus the influence of a
temperature change in the sensor's output:

is the formula defined for the sensor Sk
( see Fig. 6.16 );

Sk
is the measured wavelength for sensor Sk;

offset
Sk
is the defined offset for sensor Sk (see num­
