WARNING!
Danger for electronic components through electrostatic discharge (ESD)
Improper handling of electrical components can destroy or damage them.
▶
When the sensor housing is open, e.g. when connecting or changing the battery pack, sufficient ESD
protection must be ensured.
▶
Do not touch the PCB and electrical components.
▶
Before removing the plastic case, touch the grounded metal part of the case, or an alternative adjacent
grounded metal object (e.g. radiator or pipes), in order to discharge any static from the body.
▶
Avoid contact between the electronics and clothing.
Notes on the sending characteristic
In order to achieve the best possible transmission quality, the radio link from the terminal device to the receiving
■
gateway should be as free of barriers as possible.
The signal strength is from slightly to severely affected by concrete walls, metal shield, enclosures and hilly
■
landscapes.
For the best possible transmission performance of the antenna, no metal objects, such as pipelines, may be closer
■
than 10 cm to the antenna.
With installation, pay attention to the sending characteristic of the instrument as well as the information from the
