Explanation:
It is recommended that all current data (methods and determinations) are
stored before a validation is carried out. In order to obtain correct statistical
calculations the working memory must be cleared.
Validations must be carried out with auto start and Silo 'on'. If a
sample changer is connected you may select whether the sample changer
is to be used or if the samples are to be changed manually, see
(*) above.
When the validation series is finished a validation report will be printed out
automatically and the results can be viewed on the GLP page (
<GLP> key
and [Extend. info] softkey). In the window of the validation informa-
tion a further softkey [Histogram] is available with which the results of the
last 10 validations can be shown graphically and thus the alterations in the
reliability of the analytical system can be assessed.
The validation results are shown in a histogram against time. The Y-axis
(mean value) is automatically scaled.
