Precise adjustment using the setscrew
8.5
Before you make a precise adjustment, carry out and make a note of an investigation
with a test malt (see master copy on last page).
Disconnect the mains cable from the electrical power supply, or pull out the
coupler.
There is a plastic cap on the top of the FRIABILIMETER. Under this plastic cap, there is a setscrew inside
the housing.
This setscrew directly acts on the spring travel and thus on the force exerted on the sieve drum by the
pressure roll.

Pull handle
Remove the plastic cap.
Engage the pull handle in the top position.
Adjust the setscrew using a flat-blade screwdriver.
Turn the setscrew
clockwise (+) to increase the result.
Turn the setscrew
counterclockwise (-) to reduce the result.
Make a note of the precise setting and the subsequent check with test malt in a test log (see master
copy on last page).
One rotation corresponds to about 0.1 to 0.2 %.
At a lower friability, the effect on the investigation result is generally greater than at
a higher friability.
