d) Aligning rain sensor
The measuring system of the rain gauge has already been set ex works to a high level of exactitude.
Any alignment is therefore normally not necessary.
The alignment process takes fairly long (at least 10 minutes) and has to be carried out very exactly and con-
scientiously as, otherwise, the exactitude is much lower than that which already exists.
Proceed as follows for alignment:
•
First of all, set any rain quantity value which may have accumulated back to zero.
For this, press the "RAIN" key in normal display mode for about two seconds. After releasing the key, the
display of the total rain quantity must indicate "0".
•
Make sure that the rain gauge is clean and the count rocker dry.
•
Pour 100 ml of clear water very slowly (distributed over 10 minutes) into the cone collector of the rain sen-
sor.
CAUTION!
If the water is poured too quickly, it results in an inaccurate measuring result. Pour
the water into the cone so slowly that at no point of time water stands in the cone.
•
The total quantity displayed should be 6.5 l/m2.
•
If any other value is displayed, the so-called rocker value is to be recalculated as follows:
6.5 x current rocker value
New rocker valuet =
Actual value (display after filling with water)
•
This new value has to be entered in the configuration menu (see section 9. a), "enter alignment value of
rain sensor ") .
It is always entered in ml/rocker beat, the unit on the right is the subsequent display unit of
rain quantity!
The setting ex works is 295 ml/rocker beat (the "current rocker value" for the formula above).

When selecting the installation site, take the safety of children, pets, vehicles, etc
into consideration.
Any risk of the combination sensor's falling poses the risk of injury or danger of dam-
aging vehicles or other objects.
You can also use a hammer to insert the earth peg into the ground. However, use a
suitable piece of wood or similar in order not to damage the top end of the pipe as
this makes it impossible to connect the other pieces of pipe (loss of warranty)!
Make sure that there are no pipes or similar installed in the area where you wish to
insert the peg into the ground (e.g. hoses for irrigation systems or similar).
b) Commissioning additional sensors
If you wish to use one or several additional temperature / humidity sensors of the type "ASH555", insert the
batteries now into the sensor(s) with the right polarity. You can operate up to 8 sensors.
c) Commissioning the base station
•
Open the battery compartment on the back of the base station (remove the
installation base, if applicable).
•
Insert four batteries (AA, mignon) with the correct polarity into the battery
compartment.
Use preferably alkaline batteries.
It is possible to use accumulators but these reduce the operational life
due to their lower voltage / capacity.
•
Close battery compartment.
•
After you have inserted the batteries, all segments of the LCD are displayed
briefly.
•
After that, the base station activates the synchronisation mode for 15 minutes. During this period, the
device displays all received radio weather sensors in succession.
If all sensors used have already been received, you can terminate synchronisation mode prematurely by
pressing any key.
•
Normal display of all weather data takes place after synchronisation. Only the sunset and sunrise togeth-
er with the moon phase are not yet displayed because the time and the calendar have to be set for this
purpose.
•
You can either hang the base station on a wall (there is a corresponding opening on the back) or place it
on a level surface with the installation base.
•
If you wish to use the installation base, first hook the short claws of the base into the holders on the back
of the base station. Afterwards, tilt the base forward until the claws snap into place in the holders on the
bottom of the base station.
