SETUP
BOD Configuration
When making BOD measurements, the BOD method configuration parameters must be filled in. These
parameters will be used to flag error limits for the determination. Ignore this parameter if not making
BOD measurements.

Parameters:
• Sample min ∆ DO - the minimum acceptable difference between the initial and final DO
values for a sample. If the difference is less than this value the meter will show a warning
message when evaluating the BOD.
Range: 0.00 to 50.00 mg/L.
• Sample min end DO - the minimum acceptable final DO value for a sample. If the final DO
value is less than this value the meter will show a warning message when evaluating the BOD.
Range: 0.00 to 50.00 mg/L.
• Seed min ∆ DO - the minimum acceptable difference between the initial and final DO values
for a seed sample. If the difference is less than this value the meter will show a warning message
when evaluating the BOD.
Range: 0.00 to 50.00 mg/L.
• Seed min end DO - the minimum acceptable final DO value is less than this value the meter
will show a warning message when evaluating the BOD.
Range: 0.00 to 50.00 mg/L.
OUR Configuration
The OUR method configuration allows the user to set the parameters related to the OUR measurement.
OUR is used to determine the oxygen consumption or respiration rate. It is defined as the mg/L of
oxygen consumed per hour.
These parameters will be used to flag error limits and make dilution calculations for the determination.
Ignore this parameter if not making OUR measurements.
