Select the sample to add from the list and the number of dilutions and the dilution volumes will
be read from the sample setup. Edit the Sample’s dilutions and Seeding information if required
and click OK. Changing the dilution and seeding information on this form only changes it for
this batch. The sample and its bottles will be added to the end of the batch.
5.9 MARKING A BOTTLE
This button marks tests independently of the current criteria. If a test is marked, it is
not used in the final BOD calculation. The ability to mark or unmark records enables the user to
make judgement calls in selecting or rejecting BODs. Tests are automatically marked as
unacceptable when data is changed. To manually mark a test that meets the current criteria, move
the cursor to the row and select the MARK button. The test will be removed from the final BOD
calculation
5.10 UNMARKING A BOTTLE
Removes the marked condition for the current row. If the current row is marked
(manually or automatically) the UNMARK button adds the test back into the final
BOD Calculation.
5.11 CHECK CRITERIA
Calculates the BODs and checks the criteria for all bottles. Marks bottles that do
not meet criteria. Please note: if the Apply criteria after Finals on the Criteria
Setup form has a check mark, the criteria will automatically be applied. If you
want to check the criteria manually at any time, click this button.
