•
Open – Choose Open from the File menu to
display a list of files that you have saved on
LabQuest. To open a file, tap the file name, then
tap Open. To open a file from an external
storage source, tap the source icon (
USB,
SD) to display the files available on that
source, then tap on the file name, and tap Open.
•
Save – Choose Save from the File menu to
display the Save As dialog box where you can
tap on a source icon (
USB, SD, LabQuest) to select a destination, then tap in the
File name field to assign a name to the file.
•
Delete – Choose Delete from the File menu to display a file list similar to that accessible
by choosing open. Tap on a source icon ( USB, SD, LabQuest) to select the source
where the file is located, tap the desired file name, then tap Delete. You can delete only
one file at a time.
•
Email – Choose Email from the File menu to email the Data File, Graph, Text File, or
Screen Shot from the current file when LabQuest is connected to a wireless network with
Internet. For detailed instructions on setting up this feature, see
Emailing from LabQuest .
•
Export – Choose Export from the File menu to export the current data file in a text format
for use with other applications. Tap on a source icon ( USB, SD, LabQuest) to
select a destination, then tap OK to complete the export.
A typical use of this feature is to export a text file to an SD card or a USB flash drive for
further data manipulation on a computer with a spreadsheet program. The exported file
contains all column values from all runs in the current session, delimited by tabs. For
more detailed instructions on using this feature, see
Storing LabQuest App Files .
•
Print – Choose Print from the File menu to print the Graph, Table, Lab Instructions,
Notes, or Screen from the current file to a USB or Wi-Fi-enabled printer. For detailed
instructions, see
Printing from LabQuest .
•
Settings – Choose Settings from the File menu to adjust file settings for the current
session. These settings are specific to and saved within the LabQuest file. These settings
return to the default upon choosing New from the File menu.
o Angle Units for Trigonometric
Calculcations –
Calculated columns, curve
fits, and modeled functions may use
trigonometric calculations; choose Degrees
or Radians here. The default is set to radians.
o Number of Points for Derivative
Calculations –
Calculated columns, curve
fits, modeled functions, and even the
automatic setup for sensors (e.g., Motion
Detectors) may use numerical derivatives.
The algorithm for such derivatives utilizes a user-defined number of points. The
default value of seven points is good for many experiments, but you may want to
choose a larger number for human-scale Motion Detector experiments (e.g., our
