The number of significant digits has now been reduced by three to four digits
by omitting the prefix "milli".
Note
The above losses of accuracy by rounding off in the area of the maximum
certain places are only relevant theoretically. Most of the time they are
lower by several orders of magnitude than – as an example – the uncer-
tainties resulting from weighing out the sample.
2.4.3 Variables
2.4.3.1 Variables - Overview
Dialog window: Formula editor
Variables are automatically generated by the program during or at the end
of the determination. You can use the formula editor to access these and
either use the values for further calculations or output them as a result.
Variable types
The following types of variables are differentiated:
Name Syntax Description
Method
variables 'MV.Variable
name.Variable
identification' Method variables are variables
defined in the START command.
Command
variables 'Command
name.Variable
name' Command variables are variables
which are generated by the individual
commands in the method run. The
command variables are displayed in
the order determined by the com-
mands executed in the method run.
Result vari-
ables 'RS.Result
name.Variable
identification' Result variables are special command
variables which are generated by
CALC commands and which are avail-
able under a designation of their own.
Determina-
tion varia-
bles 'DV.Variable
identification' Determination variables are general
variables and cannot be assigned to
individual commands.
System
variables 'SV.Variable
identification' System variables are general variables
which are adopted in the determina-
tion at the start of the determination.
