9.3.4 - Wet Test 1 Flow Control
This test evaluates the rate controller flow control independent of the SharpShooter with Rate Sync system. It tests
the SharpShooter with Rate Sync system BOOST function, pump, flow control valve and flow meter functions.
Fill the sprayer with at least 100 gallons of water for these tests
Perform the following steps:
1.
Power up the SSRS Display and remain in the Manual Mode at 50% duty cycle. (This locks in a particular duty
cycle or tip and removes the SSRS Display impact on flow).
2.
Power up the rate controller to the AUTOMATIC Mode. Start job with all section switches ON and the Master
switch OFF.
3.
Set a test speed of 5.0 MPH and set the emergency brake to prevent movement that might reset the test speed
to 0.0 MPH.
4.
Switch Master Switch to ON. Both rows of nozzles should begin to pulse and spray.
5.
Check the rate controller on the UNITS selection. If TURF UNITS, using the INC/DEC toggle, set a rate of 1.5
gallons/thousand. If US UNITS, set a rate of 64 GPA.
6.
Turn on the sprayer product pump. Throttle the sprayer to maximum throttle.
7.
Once the spray stabilizes, note the resulting boom pressure. Increase or decrease the duty cycle (effective tip
size) until the pressure is near 50 PSI.
8.
Increase the rate to 2.0 gal/thousand or 84 GPA.
9.
Decrease the rate to 1.0 gal/thousand or 42 GPA.
10. Return the rate to 1.5 gal/thousand.
11. If all performs as stated, proceed to (9.3.5 - Wet Test Pressure Control page 55)
.
a. Observe that the rate controller should
achieve that rate
.
b.
Observe that the pressure will drop increase and stabilize.
a. Observe that the rate controller should
achieve that rate
.
b.
Observe that the pressure will decrease and stabilize.
a. Observe that the rate controller should return to 1.5 gal/thousand.
b.
Observe that the pressure should return to the original value.
