k In determinations with
PSAMODE, the proc-
essed curve can not be
displayed.
Smoothed Display of the smoothed curve (smoothing of the processed meas-
ured values).
I
U
Derived Display of the derived curve (1 st derivative of the processed meas-
ured values). A relative scaling in % is specified for the y axis.

In determinations with
PSAMODE, the derived
curve can not be dis-
played.
Next
VR
Display next curve
Switch to next single curve VR (the current VR number is shown in the
title line). The same function can also be initiated with the cursor key
<é>.
First the replication (R) is switched, then the variation (V),
e.g.
00-backgnd → 00 → 01 → 02 → 10 → 11 → 12 → 20 → 21 → 22 .
Once the last curve has been reached, the warning last VR: XX of
this segment reached appears in the system window.
Prev.
VR
Display previous curve
Switch to the preceding single curve VR (the current VR number is
shown in the title line). The same function can also be initiated with the
cursor key <ê>.
First the replication (R) is switched, then the variation (V),
e.g.
22 → 21 → 20 → 12 → 11 → 10 → 02 → 01 → 00 → 00-backgnd .
Once the first single curve has been reached, the warning first VR:
XX of this segment reached appears in the system window.
