15. Polynomials calculation for sensors

This section will explain how to change the polynomial to be applied when you are configuring
radiometers inside the Logbox SD graphical user interface.

Each pre-defined radiometer has a default Polynomial. (A1) This could be set to100 or 10, and
needs to be changed to have a correct reliable output in W/m².

Step1 : Look at your radiometer, and locate the sensitivity. This is located on the radiometer itself
and on the calibration certificate. (Example: 22,14µV/W/m

2

)

Step2: Calculate your own polynomial by applying the next formula : A1=1000/sensitivity
The reason for his is that the Logbox SD is measuring in mV and not in µV.

Step 3: Change your polynomial with the outcome of the formula. (1000/22,14µV/W/m

2

= 45.16)
