3.5 Operating Modes
The OM-DAQXL has four modes of operation. They are described in the
following section.
3.5.1 Free-Running
This mode is used mainly for set up. The device measures and displays all
configured analog and digital inputs. No data is logged and all settings can be
edited. While in the free-running mode the data logging mode area of the status
bar is blank.
3.5.2 Armed Mode
The OM-DAQXL will enter the Armed mode when a start trigger is configured
and the Log Data button is pressed. The data logging mode indicator in the
status bar will show an orange dot and the toolbar icon will also be an orange
color with the word Armed shown. When the configured trigger condition is
met, the device will automatically enter the logging mode of operation.
Pressing the Log Data button while in the armed mode will cause a fly-out menu
to appear. You can either skip trigger detection and enter the logging mode
automatically by pressing the red Log Data button or revert to the free running
mode by pressing the white Free running button.
3.5.3 Logging Mode
In the logging the OM-DAQXL will save data from all configured channels to
the memory location specified in the Data Session Settings. This location must
be specified prior to entering the logging mode. A maximum of 1 million data
points will be logged to a file after which a new log file will be started. When
in the logging mode new channels cannot be configured and trigger and data
session settings cannot be changed.
The OM-DAQXL features multiple options for logging data. It comes with 1GB
of internal flash memory standard in addition to both an SD card slot and a USB
host port allowing up to 64GB memory capacities to be used for storing user
data.
3.5.4 Data Review Mode
The data review mode allows you to review previously logged data or view
previously captured screenshots. The Stored Files button on the toolbar gives
access to all previously stored data for the currently logged in user. Pressing the
Stored Files button will bring you to the directories screen as shown below.
