SOUR Configuration
Specific Oxygen Uptake Rate (SOUR), also known as the oxygen consumption or respiration rate, is
defined as the milligram of oxygen consumed per gram of volatile suspended solids (VSS) per hour.
These parameters will be used to flag error limits and make dilution calculations for the determination.
Ignore this parameter if not making SOUR measurements.
