3.
Open the calibration door of the meter being
calibrated. The calibration door is the rear of the two
bottom doors.
Material Loss Risk:
Do not open the forward door. This is the clean-out door.
Opening the front bottom door will drain the hopper. Once the
front clean-out door is open it is difficult to stop seed flow until
the hopper is empty.
4.
Since only one 816-301C calibration bag is provided,
disengage the clutch (page 68) at the meter that is
NOT being tested, to disable it.
Refer to Figure 90
5.
Place calibration crank on gearbox jackshaft. See
“Meter Hand Crank” on page 25.
Population Risk:
Rotate the calibration crank only in the CLOCKWISE
direction. Operating in reverse produces results substantially
lower than chart rates.
6.
Turn the calibration crank enough turns to be sure
the meter flutes are full and the system is metering.
Empty the calibration bag.
Agricultural Chemical Hazard:
Obey manufacturer or grower recommendations for safety
equipment and protective gear when using treated seeds.
7.
Wipe all material off the flanges around the meter
door.
8.
Accurately weigh an empty container large enough
to catch material coming out of the meter, such as
the calibration bag supplied with your cart.
Refer to Figure 91
9.
Place container under open calibration door. If using
the calibration bag, loop bag handles over the door
handles and hook the bag to the front of the meter.
