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

2.1 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.

The measuring value is „frozen‟
(hold button).
3.2 Pushbuttons
Key
on/off:
press longer: switch off instrument
Key
mode:
press shortly: display of the MIN/MAX values
Press longer: invoke the configuration menu
(see chapter 4)
Key
hold:
press shortly: „Freeze‟ the current measuring value
(„HLD‟ displayed)
3.3 Switching on
The device is switched-on by shortly pushing the button .
After segment test the device shortly displays information on its configuration:
P_OF if auto-off function is activated (see chapter 4). If this function is deactivated the device is in continuous
operating mode.
After that the device is ready for measuring.
3.4 Running measurements
a) Please pay attention that no dirt gets into the vents. If this has already taken place, please do not try to
remove it. Improper treatment can damage the sensors. Additionally the device should be saved from
mechanical agitation, because this can also damage the sensors (carrier material glass and ceramic)!
Attention: In the sensor area the instrument is ESD-sensitive. Never touch or hold sensor head!
b) For fast measurements of ambient air: Hold device by the outstretched arm and sway back and forth (to
fan) to accelerate the air exchange and the temperature matching. As soon as the measured value is
quite stable, it can be read off. It may make sense to press the hold key to “freeze” all values and
therefore read them off easily.
c) If the device is held in the hand during the measurement, both temperature and humidity are altered by the
body heat. To minimize this influences the device should be held as far away from the sensor as possible
and a direct contact with the exhaled air should be avoided. Most accurate measurements are achieved, if
the device is set down and the measured value (as soon as it is stable) is read at adequate distance.

5 Offset- (Zero point) and Slope Adjustment
The temperature measuring value can be readjusted by the following settings.
However, please consider that the integrated sensors are very precise and readjustment is very rarely
needed. Erroneous settings of the parameters will probably cause by far higher errors than e.g. caused by
sensor drift in the course of time.
If you do not have access to suitable measuring references you may consider the notes on our calibration
service in chapter 6.
The corresponding display value is calculated via the following formula:
Unit = °C: displayed value = (meas. value –offset) * (1 + slope adjustment/100)
Unit = °F: displayed value = (meas. value –32°F –offset) * (1 + slope adjustment /100) + 32°F
To configure the offset and slope adjustment proceed as follows:
Switch off the device.
Press and keep button pressed. Switch on device (press shortly).
Release not before the first parameter „OFS.t‟ is displayed.
Adjust current parameter with “up” or “down” .
Switch to the next parameter with button .

Pressing after adjusting the last parameter will save the settings and restart the device
(segment test).
Please note: If no key is pressed for more than 2 minutes the configuration will be aborted. All changes
will be discarded!
6 Accuracy Check / Adjustment Service
You can send the device to the manufacturer for adjustment and inspection.
Calibration certificate - DKD certificate - official certifications:
If the measuring instrument is supposed to receive a calibration certificate, it has to be sent to the
manufacturer (declare test points, e.g. 0°C; 23°C; 40°C).
The basic settings can be only checked and –if necessary –corrected by the manufacturer.
A calibration protocol is enclosed to the device ex works. This documents the precision reached by the
production process.
