Move through the bottle number assignment prompts and accept/confirm after entering or reading
information. You may reject or skip bottles. The order in which they are read is up to you.
Retakes and correcting errors will be covered elsewhere in the manual.
Below is an example of the sample named “Effluent”. It includes three dilutions and bottle
numbers will be assigned as the bottles are read.
The top line of the display will show the Sample name and dilution of the next bottle to be read.
There may be an "i," in the top line indicating that you are working on initial DOs. There will be
a prompt for the bottle number in the bottom line. After you enter the bottle number (551), the
program will prompt you again to make sure you are ready. Finally the DO reading appears on
the display. This data will also be displayed on the BOD Analyst Pro Take Readings form.
If you need to enter bottle numbers by the YSI 5100 keypad you enter the numbers one digit at a
time using the up and down arrow keys on the YSI 5100 keypad, pressing CONFIRM after each
digit. One and two digit bottle numbers need leading zeros. (Enter "007," not "7.") Since each
digit starts at 0 it is easier to enter a "7" by pressing the down key three times.
To enter the bottle number, 294, enter "2" for the first digit. Press the up arrow key twice and then
press CONFIRM. To enter "9" for the second digit press the down arrow key once and then press
CONFIRM. To enter "4" for the last digit press the up arrow 4 times and then CONFIRM. The
progression would appear as follows.
Use the SKIP button like backspace during bottle number entry. Before pressing CONFIRM on
the last digit, pressing SKIP will move you to the previous digit so you can change it with the UP
and DOWN button. After the last digit of the bottle number is entered the program will continue
reading dissolved oxygen. The result on the YSI 5100 appears as follows
When the reading is stable (audible if programmed to beep) press CONFIRM. The program will
store the reading and then prompt for the next bottle.
All the pertinent information should be on the YSI 5000/5100 DO instrument display. The top
line of the display has remained the same. The DO reading and the bottle number are in the
bottom line. This will help you keep track of where you are in the Batch since the PC display may
be out of sight from the work space where the measurements are being taken.
Typically you will start with the first bottle in the Batch and continue all the way through the
Batch, entering bottle numbers and storing DO readings in order. As you progress the bottle
