The LCD will then show a "_" marker to
indicate the type of measurement units the
meter will use when displaying readings. The
meter will then show "- - -" on the LCD
indicating the meter is ready to take a new
measurement. Once the meter shows "- - -", it
can be placed under the spray nozzle to be

PLEASE NOTE: The most accurate measurements are made with
the meter held at a slight angle to vertical as seen in Fig. 1. This
keeps the water flowing down into the meter along the back side of
the meter and keeps it from accidentally falling on and triggering the
meter's sensors.
4.2 Turning the Meter Off
The meter will turn on any time the START button is pressed. The
meter can be turned off in two ways:
1. The meter can be shut off by pressing and holding the START
button for several seconds (about 3 seconds). As soon as the
"000"
LCD goes blank, release the START button.
2. The meter will automatically shut itself off after 90 seconds of
inactivity. This means that the user does not have to shut off
the meter after use since it will eventually shut itself off.
4.3 Changing Measurement Units
The meter can be configured to display readings in either gallons per
minute (gpm), ounces per minute (oz/min), or liters per minute
(L/min). To change the display units, the user must first turn the
meter off. Then press and hold the START button. Keep holding the
START button until the display shows "_ _ _" (about 3 seconds).
When the display shows "_ _ _" release the START button and the
display will start flashing "_" above the unit type that is currently
selected. Press the START button to change this selection. Once
the correct unit type is selected, wait without pressing the START
button for 5 seconds. The meter will then enter the new setting and
shut off.

From that point forward, the meter will always display
