5. Lower the meter chute. Push the latch back
(toward cart center). Pull the outside end of the chute
to the outside and down.
6. Open calibration door (front door, at air inlet side)
on meter(s) being calibrated. See page 46 for door
operations.
Material Loss Risk:
Open only the calibration door (front, meter air inlet side).
Do not open the clean-out door (rear door, meter air outlet
side) or material will flow in large quantities. It is generally
not possible to re-close the clean-out door, with sufficient air
seal, until the hopper is empty.
Refer to Figure 49
7. For calibration, remove calibration bag and
scale from storage compartment.
Note: The empty bag weighs 0.91 kg (2.00 pounds).
Refer to Figure 50
8. Hook bag to chute of meter under test. Place loops
over ears at outside end of chute. Place hooks in
chute latching slots.
9. Turn the crank until material is flowing to the bag.
Stop. Sweep any material in the chute into the bag.

In general, you may operate the crank as fast as is com-
fortable. For reference, at a field speed of 10 kph
(6.2 mph), the jackshaft rotates at 90 rpm (1
