6.3 Insert
the spindle by very carefully holding the viscometer side and screwing the
spindle in a counterclockwise direction.
6.4 Carefully

the viscometer handle. Insert up to the insertion marking on the spindle.
6.5 Check
to make sure the viscometer is still level.
6.6 Turn
the viscometer on the set to the desired speed (the combination of spindle and
speed should not cause the torque reading to exceed 100%).
6.7 Wait
several rotations for the reading to stabilize and mark the torque by pressing
down on the clutch lever.
6.8 Turn
off the motor when the needle is in front of the view window and read the
scale.
6.9 Calculate
torque by multiplying the factor found on the card by the unit. Use the “LV” and the appropriate spindle
number. Spindle numbers are stamped on
the top of the shaft.
