Self-Test

The results of the self-test will show "Passed" or "Failed". Use the web interface for detailed results
of the last self-test.

USB

A USB device screen shows both the unique device name and the volume label. Holding the Menu
button on a USB device screen will safely eject the device.
Each USB device also has a screen for use as a Data Logger. Holding the Menu button on this screen
will cause the instrument to load a stored configuration file from the USB device and start a
measurement. If the stored configuration file specifies, measured data may also be saved to the USB
device during a Data Logger measurement. While a Data Logger measurement is in progress, a
status screen will be displayed.
The status screen shows four items: Measurement State, Acquired Records, Completed Triggers,
and Trigger Time Remaining.
•
Measurement State: This indicates the current state of the measurement's trigger state
machine. Possible values are:
•
Acquired Records: The number of records measured so far this measurement.
•
Completed Triggers: If Trigger Count is finite, the percentage of total triggers completed
so far. If infinite, the number of triggers completed.
