The Setup menu serves to set the basic configuration. All settings are reta-
ined even after the device has been switched off or the batteries replaced.
8.1 Basic settings
When the Setup menu is open, the
± key
can be used to configure a number
of settings that are explained in the following. A good overview is also found
in the quick reference.
1. Setup —> Pitot factor
Here you can set the pitot factor S Equation (3.1) uses to calculate the flow
rate. It is 1.00 for pitot tube type L and 0.93 for type S. This value can vary
from 0.01 to 20.00 (default 1.00).
2. Setup —> Rounding
Activating this function rounds off the displayed value to a resolution of five
digits. For a display in pascals, for example, this means a resolution reduced
from 0.1 to 0.5 Pa. The result is a considerably more stabilised display under
pressure fluctuations, yet without the delay effects usual for averaging. The
device continues calculating values based on the higher resolution (ON/OFF,
default OFF).
3. Setup —> Air pressure
Here you can enter the current air pressure pcur in situ (QFE) in hPa for
calculating the flow rate with Equation (4.1) and for determining the volume
with Equation (5.1). This air pressure can range from 800 to 1200 hPa (default
1013 hPa).
