4210 Flow Meter
Section 2 Programming

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 internal identification
number.
Press Enter again and you will see the following:
The flow meter will read continuously when this screen is dis-
played. This value indicates the functioning of the ultrasonic
sensor. This display exists primarily as a diagnostic tool for tele-
phone troubleshooting. There is no specific number you should
expect to see. If the flow meter is displaying valid level/flow
readings, you do not need to worry about the numbers. The
numbers become important when you cannot get valid level
readings. If there is a number greater than zero displayed for
signal strength, the following is generally indicated:
1 = a very weak return signal. 100 = a very strong return
signal. Numbers from 10 to 90 are normal, and numbers of
50 to 90 are typical for sewers.
The important thing to remember when interpreting this
number is that the number should be fairly consistent from one
reading to the next. This number indicates the strength of the
ultrasonic return echo. A number of 1 indicates a very weak
return echo. A number of 100 indicates a very strong return echo;
generally speaking, the higher the number the better. Numbers
from 10 to 90 are normal, and numbers of 50 to 90 are typical for
sewers. Again, this number is important only if you doubt the
accuracy of the reading, or if the value itself is unstable from one
reading interval to the next.
If you press Enter again, the flow meter will display the system
voltage:
This value should be from 10.5 to 13.5 (volts DC). 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. Press Enter. The following will appear:
MODEL 4210 HW REV: XXXXXX SW REV X.XX
ID XXXXXXXXXXX
SIGNAL STRENGTH X%
SUPPLY VOLTAGE: XX.X
YSI SOFTWARE REV: XX.X
LEVEL ENABLE/ALARM
HYSTERESIS X.XXX FT (or meters)
