YSI BOD Analyst Pro - Manual (Page 54)

YSI BOD Analyst Pro ® User Manual 54
NOTE: If using the YSI 5100 with barcode reader be certain that the codes are no more than 3
characters long so that they will fully display on the 5100 instrument display.
You may also enter some bottle numbers with a barcode reader and some manually (keyboard
entry from PC or 5000/5100 instrument keypad). The program allows this in the event that some
bottles in a batch may lack barcodes or a code label is physically compromised.
6.1.3 USING A PC KEYBOARD
You can use the PC keyboard to enter the bottle numbers on the Bench Sheet before beginning
Initial readings or use the keyboard to enter the bottle numbers as you work. You may use the
number keys on your PC any time you see the Bottle Number prompt on the PC Take Readings
form. Type in a three-digit number and click CONFIRM. The program will accept the bottle
number and proceed to reading DO. Remember that one and two digit bottle numbers need
leading zeros if you are using the YSI 5000/5100. (Enter "007", not "7.")
In fact, you can use the PC keyboard for all YSI 5000/5100 DO Instrument key inputs. The
buttons displayed on the Take Readings form correspond to the keys on the YSI 5000/5100 DO
Instrument.
6.1.4 DUPLICATE BOTTLE NUMBERS
Occasionally it is necessary to have two or more bottles with the same bottle number. This will
not cause a problem as long as you can keep them straight. The program will warn you before
accepting a repeated bottle number.
If you really intend to have a duplicate bottle number, then press CONFIRM. If not press SKIP
and the program will take you back to bottle entry.
6.2 AUTO STABILIZATION
There are three techniques for entering DO readings into the BOD Analyst Pro. These were
designed originally for the YSI 5100 but apply to other YSI DO meters that work with BOD
Analyst Pro.
If you are using the YSI 5000/5100 or any of the DO meters refer to the instrument user manual
to understand DO stability criteria that may be set within the instrument programs. For example,
the YSI 5100 has an audible “beep” to notify the user that internal stability criteria have been met.
One technique is Manual. Go to Setup / YSI Instrument Parameters and set the Technique to
Manual. When you are reading DO and the reading meets stabilization criteria that you set (or
accepted the defaults) the program notifies you that the reading is stable by a green illumination
icon on the Take Readings form. However, anytime that you press CONFIRM the DO and
temperature readings will be entered and stored, regardless of stability criteria.
