MANUAL FLOWMETER CORRECTION
The flowmeter correction factor can be encoded manually. To calculate the
flowmeter correction factor the following formula can be used.
Sprayed volume
Flow correction factor =
Volume from controller
The procedure to encode the calculated flow correction factor is as follows:
Step Key Action
1 From the "Machine" setup menu select "Flow".
2 From the "Flow" menu select "Flow corr. manual".
3 Encode the new flow correction factor using the ARROW
keys.
Use this formula to calculate the new flow factor
4 Press the ENTER key and the new value is stored.
BOOST
The size of the steps which the rate will increase or decrease with when the boost
function is used.
The percentile value encoded is used for both "Boost increase" (+) and "Boost
decrease" (-).
• Minimum value = 1%
• Maximum value 20%
REGULATION ACTION
The regulation action values are used to adjust the "speed" at which the system
adjusts the regulation valve.
The fast regulation action value brings the actual rate quickly towards the required
rate. As the actual rate gets closer to the required rate the precise regulation
action value takes over and controls the valve in smaller "steps".
The two different values used (fast & precise) are explained in the following:
FAST REGULATION VALUE
The fast regulation action value affects regulation when the actual rate is far from
the required rate.
If the system is too slow to find the correct rate then the values should be
increased.
If the system is too unstable then the values should be decreased.
