Safety
The manufacturer has designed this instrument to be safe when
operated. Do not use this instrument for any other purpose than
stated.
Operating restrictions
• This instrument should ONLY be used in ships referred as
free balloons carrying open fire or inert gas balloons. On the
backside of the instrument is the marking “for use onboard
manned free balloons only”. See photo 3.3 back view.
• Make sure the battery charge level is enough to ensure
instrument operation for entire flight duration.
• The DBITX1 temperature transmitter and the DBI flight
instrument receiver combination is a secondary temperature
indicator for envelope top temperature and shall only be used
together with a melting fuse temperature flag or equal
functional device serving as primary temperature indicator.

Internal batteries
The DBI is powered by two rechargeable NiMH AAA batteries.
These can be replaced via the battery access screw cap.
Charge
• The DBI is charged by connecting the DBI interface cable
and the mains (230/110 VAC) charger.
• The charge process is fully automatic and takes
approximately one hour from fully discharged condition. This
is indicated by fast moving battery indicator.
• Completed charge phase is indicated by slow moving battery
indicator.

• Be cautious not to scratch the transparent polycarbonate
front cover with hard tools.
DBI 002 User Manual issue C7, 2005-05-25 Page 26/29
4.4. Calibration check
General
The DBI shall be checked for static pressure acquisition
tolerances every 24 month or according to national regulations.
This should be done ONLY by approved organizations to
conform with national regulations.
Approved service station can obtain drawing and instructions for
calibration from below stated service agents.
Control setup
Place the DBI in a pressure sealed chamber connected to a
pressure calibrator. The chamber shall have a viewing window
enabling reading of DBI display.
Control procedure
• Set the DBI barometric setting to 1013 hPa.
• Subject the DBI to pressure altitudes listed in paragraph 1.3
Specification - altimeter column 1 by means of a pressure
calibrator.
• Compare displayed altitude reading to be within column 2
max error tolerances.
Recalibration procedure
The DBI is recalibrated for offset error by using the DBI
application program together with above control procedure data.
This functionality shall ONLY be used by an national approved
service station.
