of frames accrues. Press Stop! to terminate the log early. The Rate display will
indicate the number of frames remaining:
 Time – Limit the logging process to a specified amount of time. When this
option is selected, enter the amount of time during which the log will run.
Double-click inside the entry item and enter the time value in the format shown.
Logging will commence when Start! is clicked and will terminate when the time
remaining expires. The Rate display will indicate the amount of time remaining:
Select a Pass/Fail Filter:
Filter out certain frames of data from appending to the log file by using the
Pass/Fail Filter. This must be selected in conjunction with the entries made in
one or more of the Pass/Fail menu items (see section 2.3 for more details on
how to use the Pass/Fail options.).
Example: To only log frames that exceeded a certain minimum amount of
energy, select Passed Frames Only. Then, check the Minimum box
in the Quantitative Pass/Fail dialog box (under Total Energy). Enter
the minimum value of the energy that is required to pass this filter.
Begin and Terminate Logging
To begin logging to a file, open the select Logging… from the File menu, then
within the Data, Results & Export Logging dialog box:
 Select a logging type
 Enter a file name
 Click OK
 Click Start! on the menu
To terminate logging to a file, click Stop!, then:
 Return to the Data, Results & Export Logging dialog box
 Uncheck the logging type
 Click OK
Example: If a log was setup to capture 1000 frames, but manually stopped at
frame 521, followed again by a restart, the logging process would
proceed to the designated frame quantity, completing a log file that
contains entries for 1,521 frames.
Important: Once a logging cycle begins, each file entry is sequentially recorded until the
log is terminated. If a log is stopped, and then restarted, the new entries will
continue to be added as before. However, the Frame counter or the Timer
(whichever might apply) will reset to 0 (zero) each time Start! is pressed. In
Export Logging, the file frame numbering does not reset, but rather continues
to increment from the last number assigned. This number is only reset each
time logging is enabled.
