tative samples. However, if your stream shows continuous flow
and the sensor detects an error, you would probably select NO
(use previous reading).
If you select DO/PH READING INTERVAL, the following will
appear:
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:
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:
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, you will see the following display:
This value indicates the functioning of the area-velocity sensor. (The
flow meter goes into the continuous reading mode whenever this
screen is displayed.) This display exists primarily as a diagnostic
tool for telephone troubleshooting. There is no “magic” number you
should expect to see. If the flow meter is displaying valid level/flow
readings, you do not need to worry much about the numbers. The
numbers become important when you
cannot get valid level/flow
readings. You can apply the following explanations to the values
displayed.
