Jolly logic ALTIMETERTWO User Manual

Basic Flight Instructions
Before Each Flight
 Press and hold the button to bring up the menu
 Let go of the button when you see Launch
You should see Ready on the screen.
You are ready to y!
After Each Flight
 You will see each of the data items for the ight
 The ight has been stored; you can turn the altimeter off or
perform other activities safely.
Flight Logic
• AltimeterTwo senses launch by sensing acceleration. Try not to bump
or jostle it too much as you load it on the launch pad, or it will sense
a false launch and collect nonsense data. If you ever have a ight with a
very low altitude, it is probably because of rough handling just before
launch.
• AltimeterTwo will automatically turn off after 2 hours from the time
that the button was last pressed, or from launch.
• If you have a ight where Coast-Apogee and Apogee-Eject times
are roughly the negative of each other, this is because AltimeterTwo
mistook a rapid deceleration after burnout as ejection.
• For multi-stage ights, AltimeterTwo will report Thrust Time, Accel-
eration, and Top Speed based on the rst engine only. Coast to Apogee
time will begin after the rst engine burnout and include subsequent
stages. Apogee to Ejection Time and Ejection Altitude will not be
reliable. Max Altitude, Descent Rate, and Flight Duration will work as
usual.
