The selection of segment and VR numbers determines what segment
curve is displayed (the simultaneous display of several segment
curves is not possible). First, the softkeys carrying the segment
names must be used to select the desired segment:
Segment# Selection of the segment Segment# .
This is followed by entry of the numbers for variation V and replication
R . For this, the system window shows the message:
VR max: ## Maximum selectable VR values
Enter VR: [00] Entry of VR
For VR the numbers for the desired variation or replication must be
entered (the entry of
* is not allowed). Without entry of VR, the default
value 00 is effective for the variation 0 with replication 0 as standard.
In determinations with background compensation
(BACKGDN instructions), the background curve
Segment-Curve-00-backgnd is shown when VR = 00 is
selected. The normal curve Segment-Curve-00 is
reached by pressing the softkey .
