Calibration (cont.)
Auto Calibration
DISTANCE/SPEED
This calibration method automatically sets the distance
calibration value while you adjust the distance. Before
proceeding, make sure your equipment and ground conditions
are as close as possible to actual working conditions. (Your
sprayer tank should be only half full.)
1. Measure a distance of 1000 ft. (300 m). Drive up to
starting marker and stop.
2. Turn selector knob to DISTANCE.
3. Flip master spray switch to MANUAL.
4. Flip master spray switch to HOLD.
5. Clear DISTANCE by holding “-” until display goes to “0”
(Red light must be OFF before clearing and display must
go to “0” all at once. If not, start over at step 2.)
6. Flip master switch to MANUAL and drive to finish marker
and stop (do not back up). NOTE: Remote Run/Hold
must be in RUN or have dust cover with jumper wire
installed.
7. If feet displayed matches actual feet driven, then no
adjustment is required and calibration is correct. If not,
continue with step 8.
8. Flip master spray switch to HOLD. (Disconnect Trak-Star
or Radar if installed.)
9. Hold toggle to “+” until number starts increasing and
red warning light comes on. (Red light indicates CAL
mode.)
10. Now use “+” or “-” to adjust display as close to possible
to 1000.0 ft. (300 m).
11. Flip master spray switch to MANUAL to exit calibration
and store new calibration value.
12. Repeat above through step 7 to verify calibration
accuracy. You should be accurate to within 2%.
13. Enter “Direct Calibration” and turn to Distance Calibration
position. The number displayed is the distance calibration
number. Write this number down for future reference.
14. Flip to MANUAL to exit calibration. (Connect Trak-Star or
Radar if installed.)
FLOWMETER
This calibration method automatically sets the flowmeter
calibration value while you adjust the ‘TOTAL LIQUID”.
1. Stop vehicle.
2. Turn selector knob to TOTAL LIQUID.
3. Flip master spray switch to MANUAL.
4. Flip master spray switch to HOLD.
5. Clear TOTAL LIQUID by holding “-” until display goes
to “0” (Red light must be OFF before clearing TOTAL
LIQUID and display must go to “0” all at once. If not, start
over at step 2.)
6. With RPM and pressure at normal operating settings,
pump a known quantity of liquid (Preferable 50 gallons
(200 liters) or more). With boom switches on, flipping
master spray switch to MANUAL should turn spray on
and HOLD should turn spray off.
7. If total liquid displayed matches actual total liquid
pumped, no adjustment is required and calibration is
correct. If not, continue with step 8.
8. With rotary selector at TOTAL LIQUID and master spray
switch on HOLD, hold toggle to “+” until number starts
decreasing and red warning light comes on. (Red light
indicates CAL mode. Disconnect Trak-Star or Radar if
installed.)
9. Now use “+” or “-” to adjust display as close to possible
to actual gallons (liters) pumped. Holding “+” decreases
and “-” increases count.
10. Flip master spray switch to MANUAL to exit calibration
and store new calibration value.
11. Repeat above through step 7 to verify calibration
accuracy. You should be accurate to within 2%.
12. Enter “Direct Calibration” and turn to Flowmeter
Calibration position. The number displayed is the
distance calibration number. Write this number down
for future reference.
13. Flip to MANUAL to exit calibration. (Connect Trak-Star or
Radar if installed.)
