dilution oxygen depletion, seed correction factor and BOD are calculated automatically. For each
set of tests having the same sample name, a Final BOD is found by averaging BODs for the
sample. When tests are checked for validity, the Final BOD is automatically recalculated using
only those tests that meet the criteria.
5.5.2 MARKING/UNMARKING
Tests can be checked for validity using limits set in Criteria Setup. Tests are checked against
limits after final readings have been complete (if the Apply Criteria after final readings) or by
clicking the CHECK button. Tests that do not meet the criteria are automatically "marked" as
unacceptable. Marked data are shown on the screen with a green background. Tests may also be
marked and unmarked independently of the criteria using the MARK and UNMARK buttons.
Upon marking, Final BOD values are recalculated using only the unmarked tests.
5.6 READING INITIAL DO’S
Select Read / Initials from the Main Menu. This will connect to the YSI 5000/5100 DO
Instrument and begin reading in the Initial DOs. As the DOs are read from the YSI 5000/5100
DO Instrument the data will be stored in the Bench Sheet.
5.7 ADD A BOTTLE
Click the NEW BOTTLE button to insert a bottle into the current sample after the
current row. You may need to add a bottle if you setup the wrong number of
dilutions when you built the batch or you need more than five dilutions for the
sample.
5.8 ADD A SAMPLE TO THE BATCH
Click the NEW SAMPLE button to add a new sample into the batch. You may need
to add a sample if you forgot to add the sample when you built the batch. The
