• After the installation of the mast, insert three batteries (AA/
Mignon) with the correct polarity into the battery compart-
ment. You will find the corresponding image in the battery
compartment (see also figure 3 on the right).
If possible use alkaline batteries.
As already described in chapter 6, accumulators
can be used, too. They, however, can have a nega-
tive influence on the operating life, coverage and
operational safety.
• During the following 5 minutes, the sensor is in the so called
synchronisation mode in which it sends one data package
every 4 seconds.
During this period of time you should insert the batteries into
the base station so that it can identify the sensor.
• Then close the housing of the multipurpose sensor again, slide the cover upwards and lock it by
turning it to the right (reverse direction than shown in Fig. 1).
• To avoid unnecessary long ways for checking the functions, the final positioning, e.g. in the
garden, should be performed only after a successfully completed functional test as described at
the beginning of this chapter.
The correct location of the multipurpose sensor is decisive for obtaining the most accurate
measuring values.
The temperature sensor inside the housing of the multipurpose sensor is positioned at
the top below the "umbrellas" in a ventilated area of the housing. Therefore, in direct
sunlight only a slightly higher temperature value will be measured.
Please ensure that the wind sensor at the tip of the multipurpose sensor is not positioned
too close to houses, trees etc., because this could falsify the measured values of the wind
speed.
That's why, the multipurpose sensor should be set up in a free space, e.g. in the garden.
• The mast must firmly stick in the soil with the multipurpose sensor being positioned approximately
2 m above the ground.
When selecting the place of installation, consider the safety for children, pets,
vehicles etc.
If the multipurpose sensor falls down, there is risk of injury or damage to vehicles
or other objects.
Make sure that there are no pipes (e.g. hose pipes for irrigating systems or
similar) at the place where the earth rod is inserted/driven into the ground.
