If invalid variables (e. g. missing endpoints) could occur in a result cal-
culation then these can be replaced with a valid value (replacement
value) by using the test function TST. In this way invalid results can be
avoided.
Syntax: TST (variable to be tested, replacement value)
4.5.4 Creating custom result templates
Under System/Templates/Custom result templates you can create
templates for result calculations (see Section 3.14.3). These result tem-
plates can be used when editing a CALC command (see Section 4.5.1
and Section 4.5.5).
In principle, creating result templates works in the same way as edit-
ing a new result in the CALC command, except that no result variable
can be assigned in the result template and no result limits can be de-
fined. These are both carried out after the template has been loaded
when editing the result calculation in the CALC command. The vari-
ables are also given without command identifications. If required, these
must be entered in the CALC command.
In the calculation formulas you can use the variables F1 to F9 as
placeholders, e. g. for the molar mass. These F-variables are automati-
cally requested after the display of the note when the result template is
loaded.
Under Note for wizard you can enter a text in the result template
which will be shown automatically when the result template is loaded
before the F-variables are requested. If you do use F-variables in your
templates then you should describe them in this note.
4.5.5 Loading result templates
Loading result templates takes place when new result calculations are
defined in the CALC command.
With [Load template] the result template selected in the selection list
is loaded and the note for the template is shown. With [Custom tem-
plates] you can show the list of your own result templates (see Sec-
tion 3.14.3).
