SB-9 Audiovariometer
with emergency battery
Instruction Manual
The small audiovario SB-9 has been built as a vario with the small size (according to the 5 ¼ inch air
norm) in order to save space. Current consumption is so low that the small accumulator, mounted
externally on it's back, is capable to supply the instrument with current for up to 10 hours.
This way the vario can also serve as an emergency variometer, in case the onboard line should fail to
supply power, apart from it's normal service during which it is being supplied by the on board line. In
contrast to a mechanical emergency vario it will deliver an acoustic signal - even in the unexpected
situation of a failure of the onboard line.
For the emergency accumulator to be always ready for service, it is being recharged from the
onboard line permanently.
Particularities:
• Operation normally from 12 V onboard supply line, should this fail, it can be switched to it's own
Emergency Accumulator.
• Runs for about 10 hours in the emergency mode, at low volume.
• After power consumption of about half the emergency accumulator's capacity, the audio generator
is switched off automatically (depending on volume: 1 to 3 hours running) to safeguard another 5
hours of - quiet - operation
• When run from the onboard supply line the instrument offers 2 different types of response, the fast
1s and the 3s response. When running on it's own accumulator, the 3s response is used.
• The emergency accumulator is permanently charged from the onboard supply line, is therefore
always charged.
• Fits in 57 mm standard cut off. Depth behind panel is 115 mm. Weight is 500 grams. Mounting of
the flask behind the instrument panel is very easy thanks to it's small size (60 x 60 x 78 mm)
