4220 Flow Meter
Section 2 Programming
YSI 600 READING INTERVAL refers to the YSI 600 Sonde. The flow meter can measure several different aspects of the stream at the same time, including pH, D.O., temperature, plus conduc- tivity.
If you select LEVEL READING INTERVAL, the following will appear:
LEVEL READING INTERVAL
• CONTINUOUS • • 15 SEC • • 30 SEC • • 1 MIN • • 2 MIN • • 5 MIN •
The LEVEL READING INTERVAL option is a way to conserve power in
If you select DO/PH READING INTERVAL, the following will appear:
DO/PH READING INTERVAL
• CONTINUOUS • • 15 SEC • • 30 SEC • • 1 MIN • • 2 MIN • • 5 MIN •
Again, this selection is offered as a means of saving battery power. After selecting the appropriate parameter reading interval, press Enter. The Setup menu will reappear. This time, select YSI 600 READING INTERVAL from the menu. The fol- lowing display will appear:
YSI 600 READING INTERVAL
•CONTINUOUS••15 SEC••30 SEC••1 MIN••2 MIN••5 MIN•
After selecting the appropriate parameter reading interval, press Enter. The Setup menu will reappear. This time select STATUS from the Setup menu. Press Enter. The following will appear:
MODEL 4220 HW REV: XXXXXX SW REV X.XX
ID XXXXXXXXXXX
HW REV refers to the hardware revision number.
SW REV refers to the software revision number.
ID is an identification number for the flow meter.
If you press Enter again, the flow meter will display the system voltage:
SUPPLY VOLTAGE: XX.X
This value should be from 10.5 to 13.5 (volts DC). Note that if you do not press Enter after the first diagnostic menu appears, the flow meter will automatically advance the display through the next two screens and finally revert to the Setup menu after a short
