Final DO Measurement
1. Access the BOD mode from the main mode screen
2. Once the DO reading is stable, touch BOD.
3. Using the bottle ID numeric touch pad, key in a sample bottle ID
number
4. Touch enter to accept the bottle ID number.
If the meter’s barcode scanning feature is employed, simply scan the
bottle to record its ID number.
If, at this point, the meter matches the seed’s identification
parameters with those stored in the memory and at least one day has
passed*, it accepts the current DO measurement as a final
measurement. Using this value along with the initial DO value and
associated information, a BOD for the seed is calculated, and stored
in memory (See Viewed Stored Data). An average BOD calculated
from all seed vales on this date will be used to calculate the seed
correction value used in all subsequent sample therefore necessary
to run seed samples on the same day as the BOD samples. Seed
BOD data will be used only if the DO loss and the final DO exceed
the criteria set under the Set BOD configuration option in setup.
*If a second BOD value is taken on the same day as the first BOD
value, the meter will ask the user if he or she wants to repeat the first
BOD measurement. Touch OK to do so and overwrite the first
measurement. Touch Quit to return to the BOD measurement
screen.
