3.3.1 Selecting a File Storage Location
In this section, choose how and where files are saved when a measurement stops.
Step 1
On your 831C, go to
Tools
3
 System Properties  Preferences
.
Step 2
From the Auto-Store drop-down menu, choose one of the following values:
• None
After a measurement, the system properties do not save or prompt you to save the
measurement data. Choose this setting if you plan to use an auto store option in the setup
file or the Scheduling firmware option (831C-SCH).
• Prompt
After a measurement ends, the meter system properties displays a dialog where you can
choose to store the measurement or cancel.
• Store
After a measurement ends, the meter system properties automatically store the data file.
Step 3
Select one of the following options from the Data Storage drop-down menu:
• Internal
The 831c has 1.8 GB of internal memory. When the available internal memory reaches 10
MB, the 831C stops automatically. If the remaining unsaved data is less than 800 kB, press
Stop/Store
7 to save it. Before you begin another measurement, download all internal
data to an external drive or PC by using the Data File Manager or G4 LD Utility.
TAKE NOTE
This option is not available as the Primary storage location for FFT
measurements with .OGG file compression.
• USB
With this option, data files saved manually (and by the meter’s auto-store preference) save
to the inserted USB drive. If there’s no USB drive available, the USB not available icon
displays in the top status bar, and data files save to the 831C internal memory.
TAKE NOTE
Choose this storage option as the Primary storage location for FFT
measurements with .OGG file compression.
• USB Backup
With this option, data files save to both the 831C internal memory and the inserted USB
drive as a backup copy. If the internal memory becomes full, data files save to the USB
drive.
TAKE NOTE
This option is not available as the Primary storage location for FFT
measurements with .OGG compression.
