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 EXPLORATORY CURVES win-

dow.

Start wave evaluation with the current parameters

entered in the WAVE EVALUATION window. The
