2 Safety
2.1 Intended use
The GFTB 200 measures the absolute air pressure, relative humidity, temperature and further derived units
in ambient air. The air and temperature measurement is done by precision sensors in the probe tube that
have to be protected from any dirt.
The additional units including „dew point temperature Td‟, „wet bulb temperature Twb‟, „absolute air humidity
[g/m3]‟ and „specific humidity [g/kg]‟ provide a precise and clear display of the current state of ambient air.
Due to the low power consumption, the device can be run permanently, for example as “weather station” or
“humidity monitor with acoustic alarm”.
The safety requirements (see below) have to be observed.
The device must be used only according to its intended purpose and under suitable conditions.
Use the device carefully and according to its technical data (do not throw it, strike it, etc.)
Protect the device from dirt.
Possible application areas include server rooms museums, churches administrative and residential buildings,
storage rooms, green houses, pools, production rooms, cooling and air-conditioning technology,
construction/building physics/defect assessment and many more.
2.2 Safety signs and symbols
Warnings are labeled in this document with the followings signs:
2.3 Safety guidelines
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures
and special safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected
to any other climatic conditions than those stated under “Specification”.
If the device is transported from a cold to a warm environment condensation may cause in a failure of the
function. In such a case make sure the device temperature has adjusted to the ambient temperature
before trying a new start-up.
2. If there is a risk whatsoever involved in running it, the device has to be switched off
immediately and to be marked accordingly to avoid re-starting.
Operator safety may be a risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
3. When connecting the device to other devices the connection has to be designed most thoroughly as
internal connections in third-party devices (e.g. connection GND with protective earth) may lead to
undesired voltage potentials that can lead to malfunctions or destroying of the GFTB 200 and the
connected devices.

2.5 Operation and maintenance advice
a.) Battery operation:
If BAT is shown in the left part of the display the battery has been used up and needs to be replaced.
However, the device will operate correctly for a certain time.
The battery has to be taken out, when storing device above 50°C. We recommend taking out
battery if device is not used for a longer period of time.
b.) Treat device and sensor carefully. Use only in accordance with above specification. (do not throw, hit
against etc.). Protect from soiling.
