Check the Agitation System
The agitation system should be checked every three to six months or if fiber values are higher than normal or
inconsistent. To check the Agitation System, follow the procedure detailed below.
Poor agitation will cause higher analysis values and poor repeatability.
1. Check the function of the agitator motor.
1.1
Place a full bag suspender in the Vessel along with the bag suspender weight, but add NO water.
1.2

1.3
Verify that the bag suspender moves up 16 times in 15 seconds (65 rpm).
2. Measure the stroke of the agitation system.
2.1
Place a full bag suspender (without the bag suspender
weight) in the empty Vessel.
2.2
Remove the top from a dark felt tip marker.
2.3
Lay the marker horizontally on the top of the bag
suspender so that the tip touches the inside wall of the
Vessel.
2.4
With constant light downward pressure on the marker,
hold the pen in place so that it rides the top tray up and
down once the agitation has begun.
2.5
Turn the instrument Power Switch to the ON position.

Turn the instrument Power Switch to the OFF position.
2.10 Remove the pen and the Bag Suspender.
2.11 Measure the mark on the Vessel wall. It should be ½ inch
long. If the motion is less than ½ inch, you will need to
replace either the Bag Suspender Tip (see next page) or
the agitator (because the old disc has flattened).
