temperature. Press Enter. The following will appear. You will
have to press the right arrow key several times to see all of the
options displayed in the following menu:
Pressing the right arrow key several times will move other
units onto the display.:
NOT MEASURED will also appear if you keep moving with the
right arrow key. This step establishes the units of measure the
flow meter will use in all subsequent displays and calculations.
GPS = gallons per second; GPM = gallons per minute; GPH =
gallons per hour; MGD = millions of gallons per day; CFS = cubic
feet per second; CFM = cubic feet per minute; CFH = cubic feet
per hour; CFD = cubic feet per day; LPS = liters per second; M3S
= cubic meters per second; M3M = cubic meters per minute; M3H
= cubic meters per hour; M3D = cubic meters per day; AFD =
acre-feet per day.
This step determines the units value the flow meter will use to
record the totalized flow volume that passes by. GAL = gallons;
MGAL = millions of gallons; CF = cubic feet; L = liters; M3 =
cubic meters; AF = acre-feet.
For the next several substeps you must have the appropriate
sensor attached to the flow meter's Parameter Port or Rain
Gauge Port (for the Rain Gauge or YSI 600 Sonde) to take
advantage of the capabilities. You can only have D.O./temper-
ature, pH/temperature or temperature alone on a given flow
meter, unless you use the YSI 600 Sonde. The YSI 600 Sonde pro-
vides multiple outputs simultaneously. You can use the Rain
Gauge with the YSI 600 sonde if you use a Y-connect cable.
Note
The pH or D. O. probes do not attach directly to the flow meter,
as their output signals are very low. You must also have the
appropriate amplifier box connected between the probes and
the flow meter.
Remember that programming for one type of sensor will prevent
the display of any references to the other in later program steps.
All sensors but the rain gauge are mounted fully submerged in
the flow stream. The pH and D.O. probes must be kept con-
stantly wet or they can be damaged.
