USE OF PRODUCT:

Turning the Meter ON/OFF
The meter will turn on any time the ON/OFF button is pressed. The meter can be shut off by
pressing and holding the ON/OFF button for 2 seconds or waiting for automatic shutoff after 90
seconds of inactivity.
Changing Measurement Units
With the meter powered on
press the SETTING button until
the desired units of measure
is highlighted, then press the
+/- buttons as needed. When
the correct units of measure are
flashing press the ON/OFF button
to exit setting mode.

Measuring Nozzle Flow Rate
Press the ON/OFF button to turn the meter on. Wait for "- - -" to show on the display. Place the
meter under the operating nozzle at a slight backward angle of 10° to 15° as shown in Fig. 2 until
the meter displays the flow rate as shown in Fig. 3. Pour out contents before starting another
reading. A press of the ON/OFF button resets the meter to check another nozzle. Readings remain
10
on the display for 90 seconds before the unit automatically shuts off.
Measuring Nozzle Wear
First determine the desired target flow rate in one of two ways. Best practice is to install a new
nozzle on your sprayer and then measure its flow rate. If this cannot be done, then reference
the nozzle the manufacturer's flow specifications for the nozzles being tested and make sure the
boom pressure matches their flow specification. Select a pressure of typical use or use 40 PSI
(2.76 Bar) to make easy comparisons to manufacturer's nozzle flow rates. See Fig. 4 for typical
nozzle flow rates. (Please verify this chart with the nozzle manufacturer's specs before use.)

Second set this desired target nozzle flow rate on the SC-2 by pressing the SETTING button and
adjusting the 0%= target value. Subsequent measurements of nozzle flows will display the actual
nozzle flow and the % error (nozzle wear) compared to the target setting. Nozzle manufacturers
typically recommend replacing a nozzle if the flow rate exceeds that of the new nozzle by 10% or
more.
Determine Nozzle Spacing to use with the SC-2
For broadcast applications with a single nozzle operating at each boom location use:
Nozzle Spacing = Boom Location Spacing (typically 20 inches or 50 cm)
For broadcast applications with twin nozzles operating at each boom location:
If both nozzles can be simultaneously measured with the SC-2 use:
Nozzle Spacing = Boom Location Spacing (typically 20 inches or 50 cm)
If each nozzle must be measured individually use:
Nozzle Spacing = ½ Boom Location Spacing (typically 10 inches or 25 cm)
For single nozzle banding or boomless applications use:
Nozzle Spacing = sprayed band width or swath width in inches or cm
For multiple nozzle directed applications use:
Nozzle Spacing = (row spacing in inches or cm) / (number of nozzles per row)
