HARDI ® MUSTANG 3500 OPERATOR’S MANUAL
APPENDIX B: FINE-TUNING FLOW
TRANSDUCER CALIBRATION VALUE
This procedure is used to verify and fine-tune the flowmeter calibration.
NOTE: Make sure the sprayer’s flow return adjusting valves are
set properly. See your sprayer’s operating manual for details.
Method 1
:
1. Put enough water in the sprayer tank to perform this test.
(Preferably 100 gallons or more. The larger the volume of water
used, the more accurate the calibration.)
2. Start the sprayer pump, and with the Master Switch in HOLD, turn
on all section valves. Place the Master Switch in MAN and run
enough water to purge all air from the lines. Turn off section valves
by placing the Master Switch in HOLD, but leave pump running.
3. Turn the rotary dial to the FLOW CAL position. Press and hold the
RESET button until the display reads 0.
4. Place the Master Switch in MAN, and run a known amount of water
(preferably 100 gallons or more).*
5. Place the console in HOLD to turn off section valves. Compare the
console’s TOTAL FLOW reading (top display) with the known
amount of water run. If the two amounts are within one or two
percent, no fine-tuning is required and you may continue set-up. If
the two amounts are more than one or two percent different,
continue with the next step.
6. Toggle the ADJUST switch to adjust the upper display until it
matches the actual amount run. This will also fine-tune the Flow Cal
factor (PPU) in the lower right display.
To verify proper calibration, repeat the procedure a second time. Write
down the new Flowmeter Calibration value (lower right display) and
keep it in a safe place. If the calibration values are ever accidentally
changed, you can simply re-enter this number.

The most accurate method to measure the volume of water run is to
place a container under EVERY nozzle and add together the amount
