5.6 Method Specifications
746 VA Trace Analyzer / 747 VA Stand
5-140
Parameter Range; Default value / Meaning
Evaluation display only
Evaluation
Title for those parameters which concern the evaluation of sub-
stances.
Mode VA, PSA; VA
Evaluation mode
Selection between evaluation mode for measurements with
PSAMODE (
PSA ) and those for all other VA measurement modes ( VA ).
Substances can be evaluated only if all substance pa-
rameters and program instructions correspond to the
selected evaluation mode.
Quantity I.peak, P.peak; I.peak
Evaluation quantity
Whereas only the wave height I.wave can be determined with waves
(DCTMODE with SWEEP), there are two different evaluation quantities
with peaks:
I.peak Peak height (current I in A)
P.peak Peak area (power P in W)
In the case of a linear baseline with
Scope = f.half or
Scope = r.half , only the area up to the peak maximum
is taken as the evaluation quantity.
I.peak
I.wave
P.peak
Scope = whole Scope = f.half Scope = r.half
This parameter is not displayed for substances recorded with meas-
urement mode PSAMODE.
