Manual Gain Calibration:

CAUTION

This test will drive the boom at full speed in the selected direction for one second.
Make sure the boom has full range of movement and if driving the boom down,
make sure it is not close to the ground.

•

The purpose of this test is to determine the sprayer boom speeds. It is recommended that
each test be performed three times and the readings averaged.

•

From the speed measurements taken, use Table 2 to determine the appropriate gain values
to use for each function. This test will provide approximate results for gain values. Proper
gain values rely on more than just boom speed so it is highly recommended to use the
automatic gain setup if possible.
