The reference profile section is marked with vertical  lines  called the average
reference cursors.  These cursors are drawn with large dashes and connected by
bars at the top and bottom of the screen to distinguish them from the other
cursors.

1.

 

Position the measurement cursors  on  the  profile section to be compared to
the reference.

The field labeled "Avg" will show the average profile  height between the
measurement cursors.  The field labeled "dAv" will now show  the  difference
between  this  value  and  the  reference reading.

When the measurement cursors are moved, the  average height and average
difference will be updated.

2.

 

To exit Average Difference mode,  press  CUR  then ABT.   The vertical
height field will now display the difference between the  cursor  heights.   See
the  hard  copy  manual  for  a figure showing the Average Difference Mode
display.

        4.6.  Printing

There are three available printing modes: "Screen"  in which the entire contents
of the screen, including the plot of the profile, is printed; "Summary Data"
prints out  only  the  data  shown  on  the  left side of the screen; "Data Send"
sends  all  data  to  the  RS-232C

                serial output instead of the printer.

Screen and Summary Data print modes are used  to  make print-outs  on the
internal printer or on the optional remote printer.  Data Send  uses  the  RS-
232C  serial output  to send the data to an external device such as

               an 80-column serial printer or a host computer.

Your choice of printer mode remains  in  effect until changed.   A  printout  or
data send can be initiated whenever the results of a scan are  are  displayed  on

                 the screen.

1.

 

Initiate "Enter Mode" by hitting the  ENT  key  if you have not already done
so.

2.  Press the white print button to change  the  print mode.    The  selection  will
     be  highlighted  in reverse video.

3.

 

With the desired mode  selected,  press  ENT  to leave  the Scan Menu, or
press START/STOP to leave the Scan Menu and begin a scan.
