How do you obtain statistics calculations?
1) Enter the allocations for the statistics calculation, see page 55.
2) Switch on the statistics calculations: Either with
, "> statistics" to "ON". The "Statistics" LED is on. Storing a method in the
method memory, the status of the statistics calculation is retained.
3) Change the number of the individual values n under "mean n", if necessary.
4) Perform at least 2 titrations. The statistics calculation are constantly updated and
printed. The values are printed in the short and full result report.
5) The statistics report can be printed with
Rules:
• Recalculated results are incorporated in the statistics calculation.
• If a result of a particular titration can not be calculated, no results for this determination
are incorporated in the statistics calculation. However, the sample counter is still
operative, i.e. the statistics calculation start afresh when the number of required
individual determinations has been performed.
• If the statistics are switched off ("Statistics" LED no longer on), results are no longer
entered in the statistics table. But the table remains unchanged. When the statistics
are switched on again, you can immediately continue working.
• If you delete results, all results of the determination with index n are removed from the
statistics evaluation.
• On method change, the old statistics table is cleared and the statistics instructions of
the new method followed.
• Old results in the statistics table can be deleted with "delete all" (,
">statistics", "res.tab:").
