Analog Vario; Analog Vario Time Constant; Digital Vario; Average Vario Time Constant - Brauniger IQ-CLASSIC Operating Instructions Manual

Please refer to memo mode to view A3
In setting mode no.24, it is possible to adjust the display of A1 and A2 so that A1 is shown in
metres above sea level and A2 in feet above sea level.

Analog vario

The analog vario display is
in steps of 0.2 m/sec.
Altogether, a maximum of
+/- 10 m/s can be displayed
in two sweeps of the scale.

Analog vario time constant

The response inertia of a variometer is determined by its time
constant. A short constant results in a fast response but makes the
display jumpy and erratic. A long time constant shows changes
in climbing or sinking very sluggishly and with a delay.
In turbulent air conditions in particular, it can be beneficial to
extend the response inertia of the analog vario. In setting mode
no. 20, the factory setting can be extended from 1 second to 3
seconds. Acoustics and speed are also necessarily given the same
attenuation.

Digital vario

The digital vario has a resolution of 0.1 m/s; It can be set by the
user as an average vario (also known as an integrating vario)
or as a net vario, which displays the condition of the
surrounding air. It is also possible to use the digital vario as an
integrator when climbing and when sinking as a net vario with
automatic switching.
This is set in setting mode no. 9

Average vario time constant

This can be set in setting mode no. 8 to between 1 ... 30
seconds. The average vario is particularly useful to determine the
average rise of the thermals when circling.
