Analysis and Processing of Result
Set a limit to the trace and make pass/fail evaluation
• Press the step keys ([

][
¯
]) to set the desired value.
This setting allows a new start value to be written for the start value string (START) on the
line of the segment being edited in the limit line table.
NOTE
Instead of directly entering the start value of the segment according to Steps 8 and 9, you
may also follow the procedure below:
(1) Press the
[Entry Off]
key.
(2) Move the main marker to the position of the segment start value using the rotary knob
(

START
allow the sweep parameter
value at the position of the main marker to be substituted into the segment start value.
After setting in this order, press the
more 3/3
key to go back to the first page of the
Segment Edit menu.
Step 10. Press the
UPPER LIMIT
key or
MIDDLE VALUE
key. This displays the upper value or
middle value of the limit range at the start point in the set parameter value field in the upper
left area of the screen.
Step 11.
Set the upper or middle value by one of the following methods using the keys inside the
Entry block:
• Enter the value using the numeric keys (
[0]
through
[9]
,
[-]
and
[.]
) and then press a unit
key (
[G/n]
,
[M/ m ]
,
[k/m]
, or
[ ´ 1]
).
• Turn the rotary knob (
m m m m
) to the right or left to set the value.
• Press the step keys (
[ ­ ][ ¯ ]
) to set the value.
This setting allows a new upper limit or middle value to be written for the upper
value/middle value string at the start point on the line of the segment being edited in the
limit line table.
NOTE Instead of directly entering the upper or middle value of the segment according to steps 10
and 11, follow the procedure below:

Edit menu (1/3).
Step 12. Press the
LOWER LIMIT
key if the limit range was first set by the upper limit value. Press
the
DELTA LIMIT
key if it was first set by the center value. The lower limit of the limit
range at the start point or the differential value limit (ranges of upper limit value and lower
limit value) is displayed in the set parameter value area on the upper left of the screen.
Step 13. Set the lower limit value or limit differential value by one of the following methods using
the keys inside the Entry block:
