•
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.
Use a single press of

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.
5.2.5
Rainfall
Th
e “Rainfall” setting can be used to control which rainfall value is displayed.
Use the “+” button repeatedly to select from “Rate,” “Daily,”, “Weekly,”
“Monthly,” or “Yearly.”
5.2.6
Graph Time
The “Graph Time” setting controls how far back the historical data gr
aph
looks to present data. Press the “
+
” button repeatedly to select from “12,”,
“24,”, “48,” or “72” hours.
5.2.7
Time Format
The “Time Format” setting controls how time is displayed. Press the “
+
”
button repeatedly to select between
“AM h:mm:ss”, “h:mm:ss AM”,
and
“h:mm:ss”. The first two will use a 12
-hr clock system and display AM or PM
as appropriate either before the time, or after the time. The last format uses a
24-hr clock system.
