Place the measuring jug under one nozzle to collect nozzle output for exactly 1
minute, then remove it.
8 Place the measuring jug under one nozzle to collect the
nozzle volume output for exactly 1 minute, then remove it.
9 Measure and record the nozzle output, nozzle size (Tier)
and section location.
10 Repeat steps 8 & 9 for each nozzle in each of the 16 boom
sections.
11 Compare the volume collected from each nozzle to the
stated volume in the nozzle manufacturer's rate chart at the
operating pressure used.
Any variation must be less than 10% (plus or minus).
Discard and replace all nozzles that deviate more than 10%
from the specified output, for example:
• AXIR110015 chart @ 5 Bar (500kPa) = 0.76 l/min
plus 10% is 0.84 l/min, less 10% 0.68 l/min
• AXIR11002 chart @ 5 Bar (500kPa) = 1.02 l/min
plus 10% is 1.12 l/min, less 10% 0.92 l/min.
TeeJet advise nozzles with a flow greater than +10% of their
stated volume are 'worn out' and should be replaced.
Do not use a worn nozzle to set the pressure setting and nozzle rates. If the
boom is not fitted with new nozzles, fit one new nozzle and use it to set the flow
rate and pressure setting. This sets the standard flow rate, pressure setting and
spray pattern with which to test the performance of other nozzles.

Calibration – Set & Check Application Rates
Illustration of the RapidFlow and RapidFire nozzle technologies.
12 Test and check any replacement nozzles by collecting and
measuring the output of each replacement.
13 Record each replacement and its output.
14 For each nozzle type tested, add the measured outputs
together, then divide the total by the number of test nozzles
to obtain the average nozzle output per minute.
eg, Using the 3TS two tier system:
• AXIR110015 Nozzle - Total spray output 15.4 litres ÷
20 nozzles tested = 0.77 l/min per nozzle.
• AXIR11002 Nozzle - Total spray output 22 litres ÷ 20
nozzles tested = 1.1 l/min per nozzle.
While doing the 'Jug Test' visually check the nozzle spray patterns and spray
angles for accuracy and, if necessary, replace any faulty nozzles.
Check boom width & section set-up values in the RCM.
Other Calibration Items
Other items critical to accurate calibration & application include:

1 Boom Width

2 Vehicle Speed
3 Flow Meter
4 Regulator Valve.
1 Boom Width
The Boom Width values are entered into the RCM controller
during the initial set-up of the machine. Check controller
settings have not been changed.
Refer to Chapter 4 'Setting Up', 'Pre-Set the Raven Control
Module (RCM)' for instructions.
In the event of any nozzles not delivering the required volume, investigate futher,
including but not be limited to;
• Cleaning the nozzles using a method recommended by the nozzle supplier
• Cleaning nozzle filters
• Replacing the nozzles.
