PRODUCT CALIBRATION SETTINGS
Review the Control Valve Settings and Tuning section on page 24 for assistance with calibrating and tuning the
product control valve.
FLOW METER RE-CALIBRATION
1. Enter a meter cal number of 10 [38].
2. Enter a total volume of 0.
3. Switch all booms off.
4. Remove a boom hose and place it in a calibrated 5 gallon [19 liter] container.
5. Turn on the boom and master switches.
6. Pump exactly 10 gallons [38 liters].
7. The readout in total volume is the new meter cal number. This number should be within ±3% of the number
stamped of the flow meter tag.
8. Zero out the total volume.
9. Repeat the calibration procedure several times to confirm the reading accuracy.
NOTE: For greatest precision, set the meter cal to 100 [378 liters] and pump 100 gallons [378 liters] of water.
10. To verify the flow meter calibration, fill the applicator tank with a predetermined amount of measured liquid
(e.g. 250 gallons [946.4 L]). Do not rely on the graduation numbers molded into the applicator tank. Empty the
applicator tank under normal operating conditions. If the number displayed under the total volume is different
from the predetermined amount of measured liquid by more than ±3%, complete the following calculation.
FOR EXAMPLE: A meter cal of 720 [190], total volume of 260 [983], and a predetermined amount of measured
liquid equaling 250 [946]:
US Units:
Metric Units:
Enter a corrected meter cal of 749 [198].
11. Enter the corrected meter cal before resuming application.
