7.2.6 Calibration commands
Command AT
<id>AT
Alignment of the interior temperature
Description:
The interior temperature is necessary for the determination of the precipitation
type (except for variant 5.4110.x
1
.xxx, see note below). With an outside
temperature range from –4 to 10 °C the interior temperature should deviate by
max.
±
2 °C (without solar radiation). With solar radiation the difference can be
up to 6±2°C.
Please note: The alignment time with great temperature changes is (due to the
compact housing) approx. 20 minutes.
Parameter > 100 are negative.
Example: AT00103 -> -3° temperature correction
Value range:
0...106
Initial value:
set in the factory
NOTE:
The variant 5.4110.x1.xxx (“Extended Heating”) uses a Pt100-sensor at the
bottom of the housing for the measurement of the ambient temperature. The
interior temperature differs from the ambient about +5°C, if the heating is off
(ambient temperature > 3°C)
Command AU
<id>AU
Request of the measuring area.
Description:
The measuring area is device-specific. Calculation of the area:
A
Meas
= 4600mm² * 1000 / AU
Parameter
Value range:
850…1200
Initial value:
set in the factory
Command AV
<id>AV<para5>
Adjusting measurement of quantity resp. intensity
Description:
Correcting precipitation quantity and intensity. Scaling in %.
Value range:
80 ... 120
Initial value:
100
