Using The Sensor For The First Time; Default Set-Up - Multiplex TEK-Vario+TAS Sensor Notice D'utilisation

3. Using the sensor for the first time

Once you have installed the Prandtl tube and
completed the various connections (silicone tubes
and sensor lead), your TEK-Vario + TAS sensor is
ready to use.
· First switch your transmitter on.
· Switch your receiver on (e.g. connect the flight batte-
ry, speed controller ...).
· After a brief period the vario will display the rate of
descent / climb and the current altitude.
· The True Airspeed sensor now carries out an
automatic calibration process. This is indicated by
a display of "-/- km/h" on the transmitter screen.
When calibration is complete, the screen displays "0
km/h" to confirm readiness.
· Once calibration is complete, the sensor is ready for
use.

4. Default set-up

The TEK-Vario + TAS sensor is delivered with the
following factory default settings:
TEK - compensation
TEK - effect
Vario address
Vario address max. climb
Vario alarm, descent rate ... m/s
Vario integration
Vario inherent rate of descent
Altitude address
Altitude max. address
Altitude alarm min.
Altitude alarm max.
Please note:
The Prandtl tube should not be subjected to moving
air during the automatic calibration process on the
ground, i.e. there should be zero wind. If calibration
is not confirmed after ten seconds or more, switch
the receiver off and on again, and this time hold a
cloth or your hand in front of the Prandtl tube for the
duration of the calibration process to protect it from air
movements.
Tip:
If the gain lead is installed, it is possible to adjust the
level of compensation in flight by means of a slider
on the transmitter. This is accomplished by assigning
the slider to a servo channel. The servo position of 0%
(servo centre) corresponds to a compensation level
of 100%. A servo position between -80% and +80%
alters the TEK effect within the range 80 to 120%. At a
servo position of -100% the compensation is switched
off.
