YSI BOD Analyst Pro - Manual (Page 62)

YSI BOD Analyst Pro ® User Manual 62
Auto: The program automatically stores the DO reading when it meets DO stability criteria
(green light illuminates). The display prompts move on to the next bottle on the Bench
Sheet list.
Dual: When the DO reading meets stability criteria (green illumination) press CONFIRM to
store the reading.
Manual: Press CONFIRM to store the currently displayed DO reading from the YSI DO
instrument. If using the YSI 5000/5100 the DO instrument display should display
STABL. The reading may not have met DO stability criteria when the reading is
actually stored.
None:
Press CONFIRM to store the current reading. The YSI 5000/5100 DO instrument will
not display STBL. The stabilization feature is essentially turned off.
There is little difference between taking Final DOs and taking Initials. The YSI 5000/5100 DO
Instrument menu is the same. The "i" in the display has been replaced with an "f". The alarms
work exactly the same way. The BOD for each bottle (dilution) and Sample is calculated as you
proceed through reading. However, the calculations for some Samples depend on the results of
others. For example, one cannot calculate the BOD of a seeded sample until the Final DO for the
seed has been performed. Below is an example of a completed Bench Sheet on Day-5.
