Wave evaluation
Automatic wave evaluation of recorded DC or NP signal curves.
The results (position of half-wave potentials and wave height) are
listed in the table of results, the calculated tangents and positions
of the half-wave potential are displayed in the
EXPLORATORY
CURVES window.
EXPLORATORY SPECIFICATION / Signal / Wave evaluation
Open the PEAK SEARCH window for starting the
quantitative wave evaluation.
Options General parameters for wave evaluation.
Manual
Manual wave evaluation. The base points for
tangent evaluation must be set manually.
Automatic
Automatic wave evaluation. The base points for
tangent evaluation are evaluated automatically.
Minimum width (V) [ > 0...5 V ; 0.1 V ]
Minimum width for wave recognition.
Minimum height (A) [ > 50 pA ; 100 nA ]
Minimum wave height for wave recognition.
Smooth factor [ 1...6 ; 3 ]
Smoothing power for the Savitzky/Golay smooth-
ing of the wave (
1 = minimum smoothing, 6 =
maximum smoothing).
Close the WAVE EVALUATION window.
Clear all the wave evaluation results entered in
the results table and the
EXPLORATORY CURVES
window.
