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 870).
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 867).
5.6.5.3 Calibration - Calibration curves
Tab: Method ▶ Evaluation - Calibration ▶ Calibration curves
Selection of the measuring command
Measuring command
Selection list with all of the VA measuring commands with data acquisi-
tion defined in the method.
Selection 'VA measuring command'
Table
The type of calibration curve is defined in the table of calibration curves
for each substance. The table cannot be edited directly and contains the
following columns:
Calibration method MLAT
Substance
Name of the substance. Substances can neither be added nor deleted
here, this must take place in the substance table (see Chapter 5.6.3, page
555).
Evaluation quantity
Measured quantity for the evaluation of the calibration curve.
