BURR CALIBRATION
The Vario+ factory calibration will accommodate a wide range of brew
methods and calibration should not need to be adjusted out of the box
for most brew methods. However, if the Vario+ is unable to grind finely
enough or coarsely enough for a particular brew method at the finest
and coarsest settings, respectively, follow the instructions below.
TO RECALIBRATE THE GRINDER TO FACTORY SETTINGS:
1. Empty all beans from the grinder.
2. Lower the micro
(5)
and macro
(6)
levers all the way to
the bottom of the range.
3. With the hopper and grounds bin
(13)
in place, press
MANUAL
(8)
, then START/STOP
(7)
and run the grinder
long enough to expel any remaining coffee; when
remaining coffee is expelled, press STOP/STOP.
4. Remove the grounds bin and insert the calibration tool
(11)
into the round hole behind the discharge chute
until the tool settles into the head of calibration screw
inside.
5. Press START/STOP to run the motor.
6. With the motor running, move the macro arm up to
setting 2 or until burr contact is heard, whichever
comes first.
3
If there was no burr contact sound when
adjusting the macro lever, move the micro arm to Q or
to the point at which the burrs make contact, whichever
comes first.
7. If the grind setting is at 2Q and the burrs are not in
contact, use the calibration tool to turn the calibration
screw toward the finer direction (as indicated on the
tool) until a change in motor pitch is heard. This will
bring the grinder back to factory calibration.
