Curve display
The representation of the substance curve as well the display of the peak/wave results
depends on the measurement mode selected:
Measurement mode y axis x axis Results
DPMODE, SQWMODE, AC1MODE
DCTMODE with SSWEEP (peaks)
CYCMODE with only 1 ramp (RAMP) I/xA U/mV U.peak

In what follows, a substance peak recorded with DPMODE will be used as a curve exam-
ple. However, in most cases the listed functions of the softkeys and the meaning of the
parameters apply to not just this example but also curves with other measurement modes.
Any differences which appear are listed specifically under "Softkeys" or "Parameter".
