5.2.3 Coefficients
In the coefficients sub-menu, you can change settings for the gain value of
some sensor values. Gain means that the sensor value is multiplied by a
“gain” or “factor.” When “gain” is larger than 1 value are increased
proportionally, when it is less than 1 they are decreased proportionally.
Generally, you should not have to change these gain values, but if you know
for sure that your sensor readings are systematically incorrect by a
proportional amount (not an offset), you can edit the following:
Rain: Register rain in greater amounts (> 1) or lesser amounts
(< 1).
Wind: Register wind at greater speeds (> 1) or lesser speeds
(< 1).
Solar radiation: Register light in greater amounts (> 1) or lesser amounts
(< 1).
UV: Register UV radiation in greater amounts (> 1) or lesser amounts (<
1). This gain is initially set to 1 and cannot be changed.
Lux conversion factor: This is not a gain for a sensor, but rather a
conversion factor. Conversion from w/m
2
to lux and vice versa needs to
take into account the wavelength of the light. The standard conversion
factor is 126.7 lux per w/m
2
. This value cannot be changed.

5.2.4 Barometer
The “Barometer” setting can be used to control whether in normal mode the
barometer displays absolute pressure (ABS), which is pressure as measured
at the sensor, or relative pressure (REL) which represents the measured
pressure corrected to sea level elevation. Use the “
+
” button to switch
between the two.
