Operating Philosophy
Bräuniger GmbH’s philosophy is to produce user-friendly instruments.
A quick press of each key lets you access the main functions of the instrument. Hold a
key down for about three seconds to call up Set-Mode for that function. From there, a
further three-second press will call up Option-Mode for that key.
In Set-Mode and Option-Mode, the keys labeled START/STOP/RESET and CLEAR-ALT
become Arrow Keys. With these you can change the display fields, which flash to
indicate they are changeable. After making changes in Set-Mode, use a short press to
return to Run-Mode or wait three seconds.
Run-Mode
During normal use the instrument is in Run-Mode. In this mode the instrument shows
sink or climb rate, airspeed (if the optional sensor is plugged in) and/or temperature,
altitude, altitude difference, time, battery condition and the activated acoustic signals.
When in this mode, all the main functions can be called up by briefly pressing the keys.
• volume of the acoustic signal (main Variometer)
• ON/OFF of the sink warning alarm (main sink alarm warning)
• change of height displays (main altimeter)
• reset height difference (main altimeter)
• START/STOP of stop watch (main time functions)
• change between TIME-CHRONO and MEMO displays (main time functions)
Set-Mode
To enter Set-Mode for a given key, press and hold the key for about three seconds; SET
will appear in the lower portion of the display. The relevant display field will flash and can
be altered with the Arrow Keys. After making your changes, either wait three seconds or
use a short press to return to Run-Mode. A three-second press when in Set-Mode will
take you to Option-Mode.
Option-Mode
When in Set-Mode, press the same key again for three seconds to bring the instrument
into Option-Mode; OPT will appear in the lower portion of the display. Here you can
change the settings of various values (see more details below). Again, the relevant field
will flash and can be altered with the arrow keys. Use a short press to keep your changes
and go on to the next option; when you reach the last option a short press will cycle the
instrument back to the first option. When you are finished setting the options, wait three
seconds to return to Run-Mode.

Switching the Instrument ON/OFF
The date and time are displayed when the
instrument is off. To turn it on, press and hold the
TIME/CHRONO/MEMO Key until you hear a beep,
and then release it. After a short display test you
will see the Start up Screen.
The Startup Screen shows the serial
number, the battery condition and the
date. The analog scale on the left shows
the battery charge.
Switching Off
To switch the instrument OFF without setting the
time, Press and hold the TIME/CHRONO/MEMO Key
for about seven seconds.
During the shutdown process, the Set Menu for
time will appear – unless a barogram was recorded
for the current flight [Model 6010 only]. Continue to
hold the key down while the instrument counts
down from 3 to 1. You will hear a beep and see
OFF appear on the display when the process is
complete.

Bräuniger GmbH
The Altimeter
General
How does an altimeter function?
An altimeter is really a barograph because it doesn’t directly measure height, but air
pressure. Height is calculated from changes in air pressure. The pressure at sea level is
used as zero height for the calculation of real height (after the international height
formula).
Why does pressure change with height? Pressure at any given point on the earth is
created by the weight of air in the atmosphere above it. Therefore, pressure reduces
with height – there is less air above you. A change in pressure of one millibar (mb) at
500 metres above sea level is a height difference of about 8 metres.
In practice, it is not as simple as that because of the many other factors that influence air
pressure. On a stable day, temperature induced differences of 1mb mean a height
difference of +/-10 metres. Depending on the weather, air pressure at sea level (QNH)
may vary from 950 mb to 1050 mb. In order to eliminate the influence of the weather, the
altimeter has to be calibrated at certain intervals. This means the altimeter has to be set
to a known height and show this height.
During rapid weather changes e.g. the passage of a cold front, the air pressure can
change by 5 mb during a day. This means a height difference of 40 metres!
Another way to calibrate an altimeter is to set it to QNH.
What is QNH? General air traffic needs a common zero point. This means that at a
certain height all aircraft show the same height on the altimeter. The reference point for
this is QNH. The QNH is the actual pressure calculated back to sea level (1hPa=1mb).
It is calculated several times a day and can be taken from the weather forecast for
aviation or it may be requested from airfields.

use the Arrow Keys. Unlike other setting changes, this edit
must be confirmed with a short-press to ALT1.
Notice that QNH is displayed below the altitude, and that it

Option 3 Corr
Pressure corrections can be made in this mode. This may

years use, is no longer exact.
The maximum correction possible is +/- 47.9 hPa.
A short press of the Altitude Key cycles you back to
Option 1.
Set-Mode ALT2
While in the ALT2 display, press the Altitude Key for three

In ALT2 Set-Mode a reference height can be set (e.g. the
relative height to a goal or waypoint). In order to do this ALT2
must be set to relative height.

Option 2 Rel Relative height, ALT2 only
For the ALT2 value, relative or absolute values can be
chosen.
If you would like to see height in meters and feet, change the
display to absolute. In Run-Mode ALT1 and ALT2 are of
equal size. You can set one of the values to feet.
TIP: To view your current altitude in both meters and feet,
change this option to ABS and set the units fo r ALT2 to m . In
Run-Mode you can now toggle between ALT1 and ALT2 .
IMPORTANT:
If you have chosen Abs for ALT2 in Option Mode, ALT1 and
ALT2 are linked together. This means that there is only one
Set-Mode for ALT1 and ALT2. Option-Mode remains
separate.
To leave this mode, change the setting „Rel“ ALT2 in Option
Mode to „Abs“. To call up ALT2 in Option- Mode you have to
switch, in Run-Mode, to ALT2 and long press the ALT1/ALT2
key twice.

temperature exactly. The temperature display has a certain
delay because the temperature sensor is measuring the
temperature inside the instrument - so it may not match the
ambient air temperature.

Option 4 Stall ( Stall Speed )
The stall alarm sounds when flying too slowly results in an
interruption to the laminar flow.
The stall alarm can be switched off (value shows 0 km/h), or
can be set from 10 km/h upwards.
Option 5 Corr Speed ( air speed correction )
A wing wheel sensor is used as a speed indicator (can be
bought separately).
Speed correction is in %. This correction is necessary when
you are under the impression that the displayed speed is
incorrect. The accuracy of the speed displayed is greatly
influenced by the mounting position of the speed sensor,
therefore, you should take care when installing the wing wheel
sensor. Inaccuracy of the wing wheel sensor can be due to
the production process in the range of +2.5% (industry
standard).
Option 6 Speed Disp Speed Display
Speed Disp shows if, and after what time lapse, change from

The temperature display appears for 4 seconds. If no speed

Barograph Recording – Model IQ-ONE+
The IQ-ONE+ includes a barograph, which records your flights in a tamper-proof format
for use in competitions and setting official records. You can set the parameters and time
intervals at which recordings are made. A data port on the right side of the instrument
allows you to connect the IQ-ONE+ to a computer (on Model IQ-ONE there is a plastic
plug in this location in lieu of the connector).
While a flight is being recorded, you cannot enter Set-Mode or Option-Mode for MEMO,
ALT1 or ALT2. This is to prevent changes of altitude after a flight has begun.

To record the flight as valid, in the logbook and on a barogram, flight acceptance must be
present. A flight will be accepted when a height difference of more than plus or minus
30m has been recognized and the recorded flying time is more than 2 minutes.
A new flight is started when leaving Set or Option-Mode and no flight acceptance for the
previous flight has been recognized.
When a flight acceptance is present, Set or Option-Mode MEMO, and Set-Mode or
