micro-trak SprayMate II - Flowmeter Calibration (FLOW CAL)

26
FLOW CAL: This position is used to calibrate the flowmeter
for accurate liquid measurement.
Every flowmeter is calibrated
with water at the factory and
assigned a “FLOW CAL”
value to make it operate
properly with the
SprayMate II console.This
number is stamped on
the metal tag attached to
the flowmeter. See Illustration 17. This is a starting point only. .
If your spray solution has a specific gravity or viscosity that is
different than water, flowmeter calibration should be done for
the specific solution (please refer to Fine-Tuning Flowmeter
Calibration in Appendix C on page 48.)
EXITING CALIBRATION: Upon completion of the calibra-
tion process, exit calibration by pressing and holding the CAL
button until the RED warning light turns off (approximately
three seconds). Basic calibration is now complete.
BEFORE
beginning application, confirm that the system is set up to do
the job tha
t you want it to. Please refer to Pre-Field System
Checkout to confirm calibration settings, nozzle selection and
overall system performance
. NOTE: You must exit CAL to
save any changes.

TEST SPEED: Test speed is a built-in ground speed simulator
that is used in performing
pre-field checks. When a
typical operating speed is
entered, the SprayMate II
will respond as if you were
actually driving that speed. It
allows you to simulate your
spraying application with water,
while remaining stationary, to
make certain that all of the equipment is operating properly and
that your sprayer can actually perform the intended application.
Test speed is cancelled by exiting CAL. Test speed will not
accumulate Distance or Area measurements.
