7. Start the main carrier pump, Rotate the display selector switch to "TEST SPEED". Turn "ON" the Master Switch
and the Boom Switches. The sprayer will start to spray. Allow the sprayer to discharge until the desired amount has
been pumped. Turn "OFF" the Master Switch.
8. Weigh the sprayer again and calculate the amount of water discharged.
9. Turn the display selector switch to "TOTAL APPLIED" and select "OPERATE" with the Mode Switch. If the
total shown on the console agrees with the total amount actually discharged, no further action is necessary. The
pressure sensor, or flowmeter, is now calibrated.
10. If the indicated volume pumped does not agree with the actual volume pumped, calculate a new calibration # as
follows:
PRESSURE SENSOR: New Cal. # =(MEASURED AMOUNT / INDICATED AMOUNT) X Old Cal. #
If the measured amount is more than the indicated amount, the new cal# should be larger.
If the measured amount is less than the indicated amount, the new cal# should be smaller.
FLOW METER: New Cal. # =(INDICATED AMOUNT/ MEASURED AMOUNT) X Old Cal.#
If the measured amount is more than the indicated amount, the new cal. # should be smaller.
If the measured amount is less than the indicated amount, the new cal# should be larger.
10. Set the mode selector to "SETUP" and select "TOTAL APPLIED". Change the cal. # using the INC/DEC
switch. Return the mode selector to "OPERATE". The amount displayed will now match the amount measured.
The flow sensor is now calibrated.
10a. An alternate method, of correcting the cal. #, at this point, is to switch back and forth, between "OPERATE/
TOTAL APPLIED AND SETUP/ TOTAL APPLIED", changing the cal. # until the Total Applied display, in
operate mode, equals the amount actually dispensed.
11. Write this number down for future reference. This will be the number to use for these specific conditions
(material and applicator configuration).
Another Method of fine tuning the sensor cal. # would be to weigh the sprayer with a full tank of water, zero out the "Total Applied",
set the GSO speed to 10 MPH, and start spraying while watching the "Total Applied" accumulate. When the "Total Applied" has
reached at least 100 gallons, re-weigh the sprayer and determine the actual amount applied as compared to that indicated by the
console. Use the method described in step 9 and 10 above to correct the Cal. #.
Fine tuning of the calibration number can also be done based on field experience.
L Psi (bAr) Mode - Material left over - Adj. Cal. # down slightly
- Short of material - Ad1j. Cal. # up slightly
L STnrd and - Material left over - Adj. Cal. # up slightly
rEFLO Modes - Short of material - Adj. Cal. # down slightly
