•
The change in height reading is live as long as you hold the

settled to a stable value and record this reading. This is your
boom speed in mm per second (mm/s) or inches per second
(in/s) if inches is the selected units.
•
Repeat the Manual Gain Test three times, repositioning the
boom as necessary.
•
Average your three readings. Typical values are between 15
and 50 inches/sec.
