Calibration [ see below ; Standard addition manual ]

Selection of calibration mode (see also Calibration
techniques with CVS and CPVS, section 6.2):

Standard addition

Standard addition. The number of additions is de-
fined in the

Determination

tab, the standard ad-

dition solutions are defined in the

Substances

tab,

and the

Dosing Devices

are defined in the

DOSI-

NOS

window.

Sample with calibration curve

Sample determination using previously recorded
calibration curves. The determination with the re-
corded calibration curves must be defined in the

Determination

tab.

Record calibration curve

Recording of calibration curves. The number of
additions is defined in the

Determination

tab, the

addition solutions are defined in the

Substances

tab, and the

Dosing Devices

are defined in the

DOSINOS

window.

Note: For the electroplating bath modes CVS and CPVS
the

Calibration

techniques are different. See Calibration

techniques with CVS and CPVS, section 6.2).

Technique [ see below ; Batch ]

Selection of measurement technique:

Batch

Measurement without solution exchange.

Batch with solution exchange

(not selectable with CVS and

CPVS modes)

Measurement with solution exchange for every
addition or calibration level.
