Fig. 8 shows a sensitive variometer setting for calm weather
conditions. Fig. 9 shows a less sensitive setting. The more
sensitive the setting, the more restless the variometer is.
Sensitive settings lead to immediate indication of small
change in height.

Installation in the model aircraft
Since the altitude, as well as the rate of climb and descent are
determined by measuring the surrounding air pressure, the
installation location should be as free from drafts as possible.
Rapidly moving air over surfaces can create pressure differences
that lead to deviating measurement results.
For this reason, variometers should never be installed outside
the model aircraft. The optimal installation location is usually
protected from wind within the fuselage of your model aircraft.
Use double-sided adhesive tape or servo tape on the back of the
Vario-DX
for fastening.
The
Vario-DX
measures air pressure. Therefore, do not wrap the
Vario-DX
in air-impermeable plastic film.
