- If all samples fail the final DO rule, the software will report the value for the sample with the highest dilution (lowest sample volume) and display a greater than (>) symbol.
- If all samples in a set fail the depletion rule and the BOD of the bottle with the lowest dilution (highest sample volume) is greater than the minimum detection, the software will report the value for the sample with the lowest dilution (highest sample volume) and display a less than (<) symbol.
- A less than symbol (<) will appear when all samples in a set have a depletion of less than that specified in the BOD Method. If the BOD of the bottle with the lowest dilution (highest sample volume) is less than the minimum detection for a given sample condition, the average will be displayed as follows:
- Diluted samples with no seed added < 2 mg/L
- Diluted samples with seed added < 1 mg/L
- Undiluted samples with no seed added < 0.1 mg/L
- Undiluted sampled with seed added < 0.0 mg/L
