5.6.5.1 Calibration- Overview
Subwindow section: Method ▶ Evaluation - Calibration ▶
Application
The way that the sample content for the substances is determined from
the peak data is defined in the Evaluation - Calibration section of the
evaluation. Only one calibration method can be selected for each method,
which is then valid for all available VA measuring commands.

5.6.5.2 Calibration - General
Tab: Method ▶ Evaluation - Calibration ▶ General
This tab contains the basic settings for the calibration.
Calibration method
Selection of the method with which calibration is to take place.
Selection no calibration | MLAT | DT
Default value no calibration
MLAT
MLAT (Modified Linear Approximation Technique) is the default calibra-
tion method for the determination of brightener in electroplating
baths. Only the Linear regression curve type is permitted for this cali-
bration method (see Glossary, page 961).
DT
DT (Dilution Titration) is a calibration method for the determination of
suppressor in electroplating baths. The analysis is based on the fact
that galvanic metal precipitation is reduced by the addition of suppres-
sor to a VMS (Virgin Make-up Solution) (see Glossary, page 958).
