CONTROL OVERVIEW
CHANNEL SETUP - OPERATION
FINE TUNE FLOWMETER
This procedure is used to verify and fine-tune the flow
calibration by catch test. The catch test result is then
compared with the system calculated volume, and the system
is then adjusted to match actual flow. The larger the sample of
water, the more precise the test and adjustment will be.
The most accurate method to measure the volume of water
run is to place a container under EVERY nozzle and add
together the amount from each nozzle. This assures that
100 percent of the water is collected and that all nozzles are
spraying equally. It is also possible to disconnect the main
boom line and run it to a large measuring container but a valve
must be installed and properly adjusted to simulate actual
field conditions.
Note: the Fine Tune Meter test is automatically preset to run
at simulated speed of 6 mph, using the current Target Rate
and Active Width.
TEST PROCEDURE:
1.
Fill sprayer tank with water - preferably 100 gallons or
more. The larger the volume of water used, the more
accurate the calibration.
2.
Place catch test container(s) to collect the water.
3.
Press Run/Hold softkey. At least one section must be
active.
4.
Run test until intended volume is reached.
HYP1100 (04-08-21)
5.
Press Run/Hold softkey to stop flow.
6.
Measure collected liquid and enter total Volume Measured
in box on screen. Press on the number to enter the
number.
7.
The new value is automatically calculated, and then
displayed in the Meter Cal Calculated box.
8.
To save value, press Confirm softkey - the new Meter Cal
is automatically saved.
