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 battery-powered installations. If your installation is
AC-powered, you can simply select CONTINUOUS.
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 time-out.
