8.1.6.2 Common Sensor Settings (aIU)
Update Interval [I]
T
he upda
te interval in seconds. This parameter defines the measurement interval for analog
inputs:
• P
t1000
• Solar radiation
• Aux rain
The range: 0.5 … 3600.
8.1.6.3 Aux Input Averaging Time [A]
The Aux Input averaging time in seconds. This parameter defines the averaging time for
ultrasonic le
vel sensor and solar radiation measurement. Pt1000 and the tipping bucket are
not aected by this setting.
Make sure the averaging time is smaller than the update interval [I]. The smallest value
0.25 s means single measurement. A longer averaging time can decrease noise. A shorter
averaging times gives a slightly smaller current consumption.
8.1.6.4 Parameter Selection [R]
[R]
defines
the active measurements.
