Technique: This field describes exactly how and when a stable reading will be stored. There are
four legal values, Auto, Dual, Manual, and None. Auto will start the auto-stable routine
immediately after the bottle number is entered and will store the reading as soon as your stability
criteria are met. This is the fastest way. Dual is similar. It will start the auto-stable routine
immediately after the bottle number is entered but will wait until the stability criteria are met, and
you've pressed CONFIRM before storing the reading. The order does not matter. If you press
CONFIRM before the criteria are met, the program will wait and then store the reading as soon as
they are met. If the criteria are met before you press CONFIRM, then the program will display
STBL on the YSI 5000/5100 DO Instrument and then store the reading when you press
CONFIRM. Manual will store the reading whenever you press CONFIRM, regardless of the
stability criteria. It will, however, display STBL on the YSI 5000/5100 DO Instrument display
when the criteria are met. None will turn the feature off. The default value is Manual.

Stabilize timeout: This field is the maximum time in seconds that the program will wait for the
reading to become stable. If the reading hasn't met your stability criteria by this time, the
program will store the reading anyway. Legal values are 5 through 500. The default value is
300.

Sample hold time: This is the hold time in seconds for Samples other than blanks. For a more
detailed explanation see the “Auto-stabilization” section above. Legal values are 1 through 300.
The default value is 10.

Sample change: This is the change in mg/L that is allowed during the hold time for a stable
reading. This field is for all Samples other than blanks. Legal values are 0.01 through 20. The
default value is 0.05.

Blank hold time: This is the hold time in seconds for blanks only. For a more detailed
explanation see the “Auto-stabilization” section above. Legal values are 1 through 300. The
default value is 5.

Blank change: This is the change in mg/L that is allowed during the hold time for a stable
reading. This field is for blanks only. Legal values are 0.01 through 20. The default value is
0.02.
