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).
