micro-trak DUAL CONTROL MT-3405D, Reference Manual

Page: 27 / 84

Ch1/Ch2 CAL Selection
The MT-3405D controls two separate systems (control loops),
so each system has its own calibration values that need to be
set. Pressing the CONT SEL button allows you to view or edit
the values for the selected controller. For example, each time
you press the CONT SEL button, you see the console display
toggle back and forth between Controller 1 & 2.
When Ch1 is selected, the ‘Controller1 ‘ yellow LED lights,
and the letters, CAL, appear in the ‘Application Rate1’ display
window as shown below.
Press CONT SEL again, and now ‘Controller 2’ lights and
“CAL” appears in the App.Rate2 as follows:
This illustration shows a WIDTH CAL value of 720 which is
the default for Loop2 single boom.
Note: CAL parameters are adjusted using the +/- buttons
under the rotary knob (the triangle shaped buttons have
no effect)

Entering Calibration Values
(cont)
MIN FLOW:
The pur pose of this calibration value is to
prevent the system
from 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.
F
or
E
xample
:
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). The system
WILL NOT
ap ply at a rate
lower than this value when spraying in AUTO. This value
should be checked/ changed for each different nozzle that
you use.
APPLICATION NOTE:
Over-application may occur with
MIN FLOW set if ground speed is too slow.
FLOW CAL:
This po si tion is used to cal i brate the flow me ter

Your Micro-Trak flowmeter has been tested at the factory
and assigned a “FLOW CAL” value to make it operate
properly with the MT-3405D console. This number is
stamped on the metal tag attached to the flowmeter. See
Illustration below. 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 in Appendix C on page 52.)
