Enter the sample date of interest. When the sample date is entered and you click on the Search
Date icon, any previous Batch from that date loads into the Bench Sheet on the screen.
Incubation Period
This is the date range of the BOD incubation period. The start date of the incubation period is set
when Initial DOs are read. The end date is set when finals are read.
Seed Correction
The Seed Correction field shows the calculated seed correction in mg/l DO per ml of seed used.
Each Sample that is set as Use as Seed in the Sample Setup form and is part of your batch will be
listed. Each seed has a unique ID# that can be associated with a particular Sample. It is assigned
by application.
Technician
Use this field to identify the person(s) involved in performing or those who are responsible for the
test results. Enter this information directly from the Bench Sheet. If saved it becomes part of the
final Bench Sheet Report.
Notes
Use the notes field for any miscellaneous notes related to the entire batch. If your field appears to
be too small for your notes, continue. The field space is bigger than it appears. Note that there is a
scroll bar to allow you to read all note information entered.
Bottle Notes
Use this field to enter bottle-specific notes. Click on the Sample Name in the bottle row before
entering the Bottle Note. As you click on each sample name the note appears for those that have
entries. Examples of Bottle Notes might be type of seed used or pH of the bottle.
5.13 COLUMN DESCRIPTIONS
Sample Name
This name identifies the sample. It was entered into the Sample Setup form and selected when the
Batch was built.
Bottle #
This the number assigned to a specific BOD bottle used for incubation. It may have been entered
manually or by barcode reader.
Pre Dil
This is the abbreviation for Pre-dilution. The column may not appear if the Pre-dilution box in the
General Setup form was not checked. It is the pre-dilution ratio for the bottle. The Pre Dil ratio
defaults to 1.00.
NOTE: Very strong samples sometimes require dilutions prior to setting up the Batch. You may
use a sizeable quantity of sample and dilute it to a ratio that will make the final dilutions practical.
Sample Volume (ml or %)
This is the sample volume in milliliters or % in the BOD bottle. The value determines the dilution
ratio for calculations. Use the Dilution Unit field in General Setup to choose whether to enter
this number in ml or %.
