The volume of each sample in mL (1 gal = 3785.4 mL). If bottles/sample mode is
used, each bottle receives a full sample volume (10–10,000 mL). Make sure that the
sample volume does not exceed the bottle volume. Sample volumes are rounded to
the nearest 10 mL.
The number of intake tube rinses before a sample is collected (0–3).
The number of sampling tries after a sampling failure occurs (0–3).
