Parameter Range; Default value / Meaning
f.double r.double
Wave-shaped curves recorded with DCTMODE are evalu-
ated only with Scope = whole .
dU.front auto, 10...500 mV; auto
Difference to front base point
Absolute voltage difference between base point at the peak/wave front
half and the peak voltage
U.peak or halfwave voltage U/2 .
With dU.front = auto , the difference is determined automatically
(default setting).
S.front auto, -99.99...99.99; auto
Slope at front base point
Slope of the baseline at its start point.
With
S.front = auto , the slope is determined automatically (default
setting).
For peak baselines of the linear type, the slope is always calculated
automatically, any numeric entry is ignored.
For baselines of the
AC2 rel. and AC2 abs. types, the slope is not
needed, any numeric entry is ignored.
dU.rear auto, 10...500 mV; auto
Difference to rear base point
Absolute voltage difference between base point at the peak/wave rear
half and the peak voltage
U.peak or half-wave voltage U/2 .
With dU.rear = auto , the difference is determined automatically
(default setting).
S.rear auto, -99.99...99.99; auto
Slope at rear base point
Slope of the baseline at its end point.
With
S.rear = auto , the slope is determined automatically (default
setting).
For peak baselines of the linear type with
Scope = whole or Scope =
f.double/r.double , the slope is always calculated automatically, any
numeric entry is ignored.
For baselines of the
AC2 rel. and AC2 abs. types, the slope is not
needed, any numeric entry is ignored.
