Once you have recorded the measurements of a pulse window (except the
t=0 window), the "Work Sheet" selection on the main menu is activated.
Select "Work Sheet" and then "Display", and the work sheet window is
displayed.  This work sheet is the same as the data table appearing on
the back of your Laboratory Exercise, except that the rows and columns
are reversed.  The measurements you have recorded will appear in their
appropriate locations.

Follow the directions in your exercise to compute and fill in the entries
in each column of the work sheet.  (Note the notation used to indicate
powers of ten in the work sheet entries.  If this is unfamiliar to you
ask your instructor to explain it.)  As you fill in each column, you may
at any time press the "Check" button at the end of the column.  The
values you have entered will be checked for "reasonableness", and you
will be informed if any of your values are clearly in error.  You can go
back to the pulse windows to make new or repeat measurements at any time.
Simply choose "Return" on the work sheet menu (note that the work sheet
has its own menu), and then select "Pulse" from the main menu.  Remember
to record your measurements before returning to the work sheet.

If for some reason you want to completely recalculate a column, you can
erase it.  Select "Erase" from the work sheet menu, and specify the
column you want to erase, or "All" to clear the entire worksheet.
Erasing the worksheet will also erase the measurements.  To re-enter the
measurements, select "Pulse".."Record Measurements" from the main menu.
You need not return from the work sheet to do this, unless you want to
actually remeasure some pulses.

When you have completed all entries in the work sheet and checked them
for resonableness, select "Work Sheet".."Print" for a hard copy of the
table to turn in with your exercise.
