Capturing the display presentation using one image for each ping

During normal operation it can be useful to capture a sequence of display presentations.

Each screen capture you make is saved in .jpg format on the Processor Unit hard disk. The file name reflects the current date and time.

Procedure

Make sure that the screen capture mode is set to Sequence.
You can choose either a single screen capture or a sequence with multiple screen captures. Open the Screen Captures dialog box to select screen capture mode.
Observe Screen Capture on the top bar.
Select Screen Capture on the top bar to start the sequence.
You can also use the Screen Capture button on the Operating Panel.
Note:
Operating Panel (Mk1): Press Record to make a screen capture.
Select Screen Capture one more time to stop the sequence.

In Sequence mode a new screen capture is created for every ping.

Each screen capture you make is saved in .jpg format on the Processor Unit hard disk. Alternatively, you can use a USB flash drive or hard drive to save the screen captures. Use Screen Capture File Location to define where to save your screen captures.
