FLOW CAL:
This po si tion is used to cal i brate the flow me ter
for ac cu rate liquid mea sure ment.
Every flowmeter is
calibrated with water
at the factory and
assigned a “FLOW CAL”
value to make it operate properly with the
FlowTrak II console. This number is stamped
on the metal tag attached to the flowmeter.
See Illustration 13.
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
Flow me ter Calibration on page 24.)

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 FlowTrak II will
respond as if you were actually driving that
speed. It allows you to simulate your monitoring
application, while remaining stationary, to make
certain that all of the
equipment is operating
properly and that your
monitor can actually
perform the intended application. Test speed is cancelled by
exiting CAL. Test speed will not accumulate Distance or Area
measurements.

MIN FLOW:
The pur pose of this calibration value is to warn the
operator when applying below the recommended minimum
rate for the nozzles. The
minimum flow rate
in gallons per minute
(li ters per minute) based
on the nozzles being used, for the en tire boom
on the sprayer. DO NOT enter the actual flow
of your spray application. For example: If the
min i mum flow rate for the nozzle you are using is .22 GPM at
their minimum recommended pres sure and your boom has 20
nozzles, enter 4.4 as the MIN FLOW value (.22 x 20 = 4.4). This
value should be checked/ changed for each different nozzle
that you use.

ENTER TARGET APPLICATION TEST SPEED INTO CON SOLE
Put console in Hold, and press and hold the CAL button for 1 sec.
to enter calibration. Turn rotary switch to TEST SPEED position.
Use the “+” or “-” button to enter target application speed. Do not
exit calibration mode.
Put console in RUN and turn rotary switch to RATE position. The
console should begin monitoring at the simulated test speed.
TEST SPEED will automatically cancel when you exit the CAL
mode or when power to the console is turned OFF.

EXITING CALIBRATION:
Upon completion of the cal i bra-
tion process, exit calibration by pressing and holding the
CAL button until the RED warning light turns off (ap prox-
i mate ly three sec onds). Basic cal i bra tion is now com plete.
BEFORE beginning application, confirm that the system is
set up to do the job that you want it to. Please refer to Pre-
Field System Checkout to confirm cal i bra tion settings, nozzle
se lec tion and overall system per for mance. NOTE: You must
exit CAL to save any changes.
