Investigation
Samples Used to specify the number of samples to be used in the investigation mode. Up to
ten samples can be selected. On the main window, these will appear as numbers 1
through 10 in the Pass Fail columns.
File Size
(FIFO Records) Enter the desired File Size. The required hard disk space for the requested file size is
displayed to the right of the data entry box and cannot exceed 2.1 gigabytes. Data is
stored to the history file after each NDT analysis.
Test Result
Flashes The number of times the results of each test will flash on the screen.
Display HPF
(Hz) Sets a frequency limit for the display window, such that all data at that frequency and
lower will be displayed as “0.” Thus, only data above the HPF value will be
displayed.

The Input Channels Tab allows you to state the channel type (Trigger or Response), name the channel, and
set the channel parameters. Channel attributions can be copied and pasted to other channels.

conductor of the input channel BNC connector.
