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 WAVE EVALUATION window for starting
the quantitative wave evaluation.
Options General parameters for wave evaluation.
Manual
Manual wave evaluation. The base points for tan-
gent 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
