then press CONFIRM.
To enter "4" for the last digit, press the up arrow 4 times, then CONFIRM. The SKIP button is
used 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.
When the reading is stable, press CONFIRM. The program will store the reading, display a brief
message and then prompt for the next bottle number.
All the pertinent information is 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. When the DO reading is stable,
press CONFIRM. The program will store the reading and then go on to the bottle number prompt
for the next bottle in the Batch. 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 turn.
As you go along the bottle numbers and DO readings will be added to the Bench Sheet. Below is
an example of this screen about halfway through a Batch.
