Auto Power Off
Timed Auto Power Off
If it is running on battery power, the GLX will auto-
matically save your data and shut down after a certain amount of continuous idle
time (5 minutes by default).
To set the idle time that must elapse before auto shut down on battery
power, see “Auto Power Off” on page 85.
If the GLX is running on AC power and the battery is fully charged, it will auto-
matically shut down after 60 minutes of idle time.
The GLX will warn you that it is about to shut down 30 seconds before it actually
does. If you see the warning, press
to proceed with the shutdown, or press
to keep the GLX turned on.
Battery Auto Power Off
The GLX will also save data and shut down automat-
ically if the batteries drain to a critical level. Connect AC power before turning
the GLX back on.
Auto Data Save
Just before the GLX shuts down, it will save the open file
(which includes all data, displays, calculations and set-up information). If you
have named the file, it will be saved under that name. If you have not named the
file, it will be saved with the filename “Untitled.”
Resuming after Auto Power Off
To resume your work after the GLX auto-
matically shuts down, push and hold the power button (
) for about 1 second to
turn it on. If the automatically saved file does not open automatically, go to the
Data Files screen (see page 78) and open the file. (See page 80 for instructions on
opening a file.)
If you have set the Startup Action of the GLX to “Open Last Experiment,” the
file will automatically open when you turn on the GLX. See page 86 for more
information.
Sleep Between Samples
If the GLX is running on battery power and collect-
ing data at a rate of once every 30 s or slower, and it has been otherwise idle for
the set auto-power-off time (see page 85), it will “sleep” between samples. When
the GLX is sleeping, the screen and any connected sensors are turned off to save
power, and the green LED on the front of the unit blinks once every two seconds.
When it is time to collect a data point, the GLX wakes up briefly, records data,
and goes back to sleep. Press any key to wake up the GLX.
The Record Button
Default Recording Mode
Whenever you have one or more sensors connected
to the GLX, you can press
to start data collection. In its default mode, the
GLX will begin recording data continuously from all connected sensors. Press
again to stop data collection. To start recording another data run, press
yet again.
Sticky Start
Use the Sticky Start feature to prevent data collection from being
unintentionally stopped when you take the GLX on an amusement park ride. To
start data collection with Sticky Start, press and hold
for about 5 seconds.
You will hear three beeps and see the Sticky Start icon ( ) appear at the top of
the screen. Data recording will continue after you release
. To stop data
