4230 Flow Meter
Section 2 Programming

Operation of Super Bubble will cause an increase in power con-
sumption, because the air pump has to run. If your flow meter
operates from AC power, leave Super Bubble on. If your instal-
lation is battery-powered and the flow is generally stable
(without sudden increases), you can probably turn Super Bubble
off. Again, some experimentation may be necessary.
If you select DO/PH READING INTERVAL, the following will
appear:
Again, this selection is offered as a means of saving battery
power (and prolonging the life of the D.O. sensor. 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 following 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. The following will appear:
HW REV refers to the hardware revision number.
SW REV refers to the software revision number.
ID is an internal identification for the flow meter.
If you press Enter again, the flow meter will display the system
voltage:
The supply voltage should be from 10.5 to 13.5 (volts DC). PUMP
DUTY CYCLE tells you how much the air pump is running. The
value is refreshed every few minutes and should generally
average below 20%. If you see a value consistently higher than
this, check the bubble line, look for leaks, or check the air system
inside the flow meter.
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.
Return to the Setup menu if the unit has not already done so.
This time select ENABLE/ALARM HYSTERESIS from the
menu. The following will appear:
