4.1 Taking a Measurement
Assure batteries have been installed in the
meter. Press the
START
button to turn the
meter on. The LCD will flash “000”
momentarily indicating it is working properly.
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
tested (you have 60 seconds to place the
meter under the nozzle). Placement of the
meter under the nozzle should be brisk and
certain so that all the flow from the nozzle is
transferred quickly to the meter (See Fig 1).
As the meter fills with water, the display will
start flashing “- - -“; this indicates that the
reading is in progress. As soon as water
reaches the meter’s upper sensor, the flashing
stops and the flow rate is displayed on the
LCD (See Fig 2). This flow rate
will continue to be displayed on
the meter for 90 seconds or until
the
START
button is pressed to
start a new reading. Once the
reading has been displayed, the
water can be poured out of the
open top of the meter (See Fig
3). Pouring out the contents of
the meter will not affect the
reading being displayed on the LCD. If a reading must be re-started
for some reason, simply empty the meter and re-press the
START
button to ready it for a new measurement.

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
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
readings in the new units.
