Syntax
Description
'Command name.Vari-
able name'
Command variables are variables which are generated by the indi-
vidual commands in the method run. The command variables are
displayed in the order determined by the commands executed in
the method run.
Automatically
calculated result
variables
'RS.Result name.Varia-
ble identification'
Automatically calculated result variables are automatically gener-
ated by the program during the evaluation.
'RS.Result name.Varia-
ble identification'
User-defined result variables are generated from the results defined
by the user.
'DV.Variable identifica-
tion'
Determination variables are general variables and cannot be
assigned to individual commands.
'SV.Variable identifica-
tion'
System variables are general variables which are adopted in the
determination at the start of the determination.
'CV.Variable
name.Variable identifi-
cation'
Common variables are client-specific variables, which are adopted
from the table of the Configuration program part at the start of
the determination and assigned to the determination.
'GV.Variable
name.Variable identifi-
cation'
Global variables apply to all clients and are adopted from the table
of the Configuration program part at the start of the determina-
tion and assigned to the determination.
Entering variables
Variables must always be entered with an apostrophe ' at the beginning
and at the end (e.g., 'DV.DUR').
NOTE
When using variables, always observe their data type (Number, Text
or Date/Time).
Variations and replications
Because of the fact that in voltammetry all data is saved in a single data
set when working without solution exchanges, all of the result variables
belonging to one voltammogram are clearly distinguished by an index X
for the Variations and another index Y for the Replications.
Variation refers to a measurement after modification of the measuring
solution, e.g., after a standard solution has been added.
Replication refers to an identical repetition of a measurement.
The following rules apply for this:
