A trigger should be produced and the capture continues to the end. While
capturing, you should have seen the waveform for Channel #1 go from a zero
baseline in the center of the channel to a sine wave within the grid on both the
color display and the chart.
Note: you do not need to run the chart when you capture data.
[RUN / HALT]
Data capture records can be reviewed on the color display as well as on the
chart paper. Typically, the review is done on the display and then sections of
interest are printed on the paper. During review, the timebase can be expanded
or compressed to give appropriate detail of the signal.
HOW TO
[MODE] [DATA RECORD REVIEW] [SCREEN PREVIEW]
[PREVIEW SETTINGS] [NEXT VIEW FORMAT] Continue to press this
key until chart 4 is selected. [ACCEPT WINDOW]
[CURSOR SELECT A] Turn encoder wheel so cursor A is positioned just to
the left of the trigger point (dotted yellow line on the display).
[CURSOR SELECT B] Turn encoder wheel so cursor B is positioned just to
the right of the trigger point (dotted yellow line on the display).
[PREVIEW SETTINGS] [SET WINDOW TO CURSORS]
[CURSOR SELECT A] Turn encoder wheel so cursor A is placed near the
trigger point. [t - EXPAND ABOUT (A)] The expansion is around where the
cursor A is set.
[OUTPUT ...] Use encoder wheel to select screen print to paper.

[EXIT PREVIEW] [SETUP PLAYBACK] [SETUP OUTPUT FORMAT]
Turn encoder wheel to select format to be Y-T Chart #4.
[SET WINDOW] [CHANGE METHOD] Select the method of data expression
to show the region of capture window.
[SET START POINT] Turn encoder wheel to 15%.
[SET END POINT] Turn encoder wheel to 25%. [EXIT]
[MODIFY SETTINGS] Set t-expansion:
compress the timebase for data playback to the chart. For long data records, it
is suggested to use maximum compression for the first playback to conserve chart
paper. Then, expand the playback to get the detail you need. As you change the
starting and ending points from 100%, you can expand the playback timebase.
[<<FIELD>>] Verify the Header is ON and the Trig Mark is ON. [EXIT]
