Do not in any case change the pairs of values of the other sensors as this would lead to wrong
measurements of your weather station.
Example for a value calculation:
Additional temperature sensor at ZA with linear output of 10mV / °C, 0V at -40°C and a maximum
value of +200°C.
The calibration value pairs for the first basic value are (raw value 0 and temperature -40°C):
!L5,1,F0 und !L5,1,W-40
The calibration value pairs for the second basic value must be in between the min and max values.
(i.e. raw value 500mV and tempe10°C):
!L5,2,F8002 und !L5,2,W10
The calibration value pairs for the last basic value are (raw value 2400mV and tempe200°C):
!L5,3,F38409 und !L5,3,W200
Between these basic values the real measured values are calculated by simple cross multiplication.
I.e. if the raw value is 19500 you'll need the calibration value pairs 2 and 3.
Calculation:
(38409-8002)/(200-10) results in 160/°C.
Then (19500-8002)/160 leads to 71.9.
At last you add the value of basic value 2 to 71.9 (71.9 + 10).
The temperature at a raw value 19500 therefore is 81.9°C.
