+/- keys.
Step 8
If tested application is not
satisfactory:
a) In Auto mode - if application rate is
not being achieved:
i) Operating pressure will climb if
nozzles are too small or blocked
or speed is too slow.
Likewise, if your pressure fi lter is
blocked (even partially), you may
experience excessive pressure at
the pump.
Make adjustments accordingly.
ii) Operating pressure will fall if
nozzles are too large or speed
is too slow. Make adjustments
accordingly.
b) In Manual mode - the Controller
application rate can be altered by:
i) Adjusting pressure up or down to
increase or decrease rate of
application (use +/- keys).
ii) Adjusting spraying speed up or
down to decrease or increase
rate of application.
iii) Changing to a different nozzle
capacity.
Repeat necessary testing procedures
and calculation of application rate if
adjustments or changes are made.
Calibration Procedure
c) For land area covered, use the
formula:
Area Covered (ha) =
Tank Volume (litres) ÷ Spray
Application Rate (l/ha)
eg, 2000 ÷ 50
= 40 hectares
d) For tank volume required, use the
formula:
Tank Volume Required (litres) =
Area (ha) x Spray Application
Rate (l/ha)
eg, 20 x 50
= 1000 litres
Step 9
Add The Correct Amount
Of Chemical To The Tank
a) For land area rates (litres or kg
per hectare), use the following
formula:
Chemical Required (litres) =
Tank Volume (litres) x
Recommended Chemical Rate
(l/ha) ÷ Spray Application Rate
(l/ha)
eg, [2000 x 2.0] ÷ 50
= 80 litres
b) If chemical recommendation is
given in water volume rates use
the following formula:
Chemical Required (litres) =
Tank Volume (litres) x
Recommended Chemical Rate
(l/100 litres) ÷ 100
eg, [2000 x 4] ÷ 100
= 80 litres
All nozzles have a pressure and fl ow rate range to
acheive the best results.
Ensure you have selected the nozzle which best
suits your application to avoid any problems.
NOTE
Full instructions of controller operation are
contained in your seperate Controller Manual.
NOTE
Mix only the amount required. Avoid wastage and
the problem of needless chemical disposal.
