Auto save function
With the aid of the auto save function (Auto save 'on') determination
files can be automatically stored in the internal memory, on a data card or
(via an RS232 interface, see page 228) on a personal computer. Always
make sure that sufficient memory space is available for this.
If the auto save function is used then care must be taken that only unambiguous
and different file names are created. If an attempt is made to overwrite an existing
determination file with one with the same name the safety query which this
produces will interrupt the processing of the sample series. Use the possibility of
combining date, time and/or sample number for the automatic creation of file
names, see page 34f.
A typical determination which includes a titration requires approx. 5 - 10 KB
memory. The file manager can be used to determine the amount of free
memory in the internal memory or on a data card.
The file manager can be used to copy determination files at a later date or to
copy them onto a data carrier from the results window.
Determination data
The contents of a determination file also includes, apart from the measuring
data produced (measuring point lists of the titrations and measurements,)
the settings and parameters which are required for a re-evaluation together
with additional information which is used for a GLP-conform presentation of
the determination. Details can be found in the table below.
