Then disconnect the GlassBuddy from your PC or
laptop and switch the GlassBuddy off. For activating
the updates press the and keys
simultaneously and hold them for approx. 4 seconds.
In this way you reach the boot loader menu.
You can now choose between two firmware versions
which are displayed with their respective version
numbers. You can choose the desired version by
pressing the or keys and activate it by
pressing .
A maximum of two firmware versions can be saved
to the GlassBuddy. When transferring a new ver-
sion to your device, the version which is currently
not activated will be overwritten.

16 Tips and Tricks
The GlassBuddy works with a laser wavelength
of 650 nm. Due to its conceptual design, the
Glass Buddy cannot detect the characteristics of
glass und glazed units which cannot be displayed
with this wavelength.
All factors which have an influence on the reflection
of the laser beam on different surfaces, also have
an influence on the measuring result und thus the
evaluation. In individual cases this leads to addition-
al information, such as “!” or “Details not avail-
able” to be displayed together with the result.
In some cases, an insufficient reflection on one
or several surfaces can generate the message
“Measurement not possible”. The correct result can
usually be obtained by repeating the measurement.
It often already suffices to thoroughly clean the
accessible glass surfaces in order to improve their
reflection properties.
The weather-related steaming up of the sensor slit,
e. g. due to a quick transfer from a cold into a warm
environment, can lead to measuring errors. Please
wait for a few minutes until the device has adjusted
to ambient temperature.
Depending on the light conditions, it might also be
helpful to change the position of the GlassBuddy
on the glass surface. The GlassBuddy does not
necessarily need to be positioned vertically for
achieving correct measuring results. Only make sure
that all the four feet rest firmly on the surface to
be measured and that the GlassBuddy is not moved
while performing the measurement.
The GlassBuddy is supplied readily calibrated. A
new calibration is usually not required. If you detect
a permanent malfunctioning of your GlassBuddy,
a calibration (involving additional costs) might be
necessary. Please contact your dealer.
