6.15 Calibration

WARNING: ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN

WATER ONLY! IN ADDITION, WEAR PROTECTIVE
CLOTHING WHEN CALIBRATING YOUR SPRAYER!

Why must you calibrate a sprayer?

A nozzle selection chart will tell you what application rate you should
expect. Variations due to nozzle wear, errors in pressure adjustment, and
tractor speedometer can result in a possible error in application rate.

How do you calibrate a sprayer?

Calibration kits are available from HARDI, #818103 for US gallons &
#818104 for metric calibration.
Following are some tips to remember when using the calibration kit
method:

• When determining the length of time required to drive the recommend-

ed distance, drive in actual field conditions with a half-full tank.

• Repeat the test several times, each time avoiding the tracks from the

previous test. Take the average of the times recorded.

• Calibration of the sprayer should be completed at the beginning of the

season and repeated after every 2 to 3 full days of spraying, and every
time you change volume rate or use new nozzles.

• Before you calibrate, check the flow of each nozzle. If it puts out more

than 10% of its original volume, replace it.
