from each nozzle. This assures that 100% of the water is collected
and that all nozzles are spraying equally. It is important to perform
this procedure at a flow rate similar to that which will be used in the
field.
Method 2
:
Check your Flow per Nozzle
If the total number of nozzles was entered into SYSTEM CAL, then the
flow per minute position of the rotary switch displays flow per nozzle per
minute in ounces per minute or liters per minute in metric. To verify
accuracy of flowmeter calibration perform the following procedure:
1. Put enough water in the sprayer tank to perform this test, 100
gallons or more.
2. Start the sprayer pump, and with the master switch in HOLD,
turn on all section valves.
3. Turn the rotary switch to Flow Per Minute position.
4. Toggle the master switch to MAN.
5. Using the adjust switch, adjust the pressure to your target
pressure.
6. After 30 seconds, note the reading in the lower right area of the
display. This is the flow per nozzle in ounces per minute or liters per
minute, in metric.
7. Using a container with fluid ounce graduation markers, catch the
flow at each nozzle for one minute, record each catch - add all of the
catch tests together and divide the sum by the number of nozzles
tested. If the result is less than 2% of the value displayed in flow per
minute, do not change Flow Cal. If result is greater than 2%, adjust the
Flow Cal number by that percentage. This is an inverse relationship,
so if the catch test was 5% greater than displayed value, reduce the
Flow Cal by 5%. After adjusting Flow Cal, it is strongly recommended
to run catch test again to verify.
