Setup Autosave
To select the Autosave feature, press the RIGHT arrow key when Autosave is highlighted. This
allows the user to setup the instrument to automatically store measurements, and to start a new
measurement without explicitly saving the old one. This mode is convenient when taking fast,
repetitive measurements, as well as when it is not necessary to review each measurement
immediately after taking it. The files created by the F-900 are saved in .csv (comma separated
value) format, to be opened with Microsoft Excel or other spreadsheet program.
In the
Setup Autosave
menu, the top line of the display will read “enter” and “save” and the
directional arrows. Next to is Autosave and “Yes” or “No” indicating whether this feature is turned
on or off. Below Autosave is the “Interval” option where the user can set the time interval. This is
the length of time in seconds between saves, when the autosave feature is selected. The default
autosave interval is 10 seconds.
To set the instrument up to automatically store measurements press the RIGHT arrow key
to highlight the word “no” on the display, then press the UP/DOWN arrow to switch to “yes”.
Press the SAVE key to save the configuration. After saving, it will exit to the Setup Menu.
To set the instrument up to
not
automatically save measurements, toggle the UP/DOWN
arrow key until “no” is on the display, then press the SAVE key to save the configuration.
When Autosave is highlighted, press the UP/DOWN arrow to get to the Interval line and
then use the RIGHT arrow key to highlight the time interval value. Press the UP/DOWN
arrow key to change the time interval. Press SAVE to save changes.
