To remove the measuring system after the measurement, fi rst open the coupling sleeve for the
bob, then unscrew the measuring cup ring.
When unscrewing the measuring cup, you must hold the measuring
system tightly with one hand to avoid dropping the cup and bob!
When using disposable measuring cups, eject the disposable measuring cup with the pusher.
V.4 Measurement with Cone/Plate or Plate/Plate Measuring Systems
Installing and adjusting the measuring cone or measuring plate
When installing a cone or plate, the lower plate must be in the down position (move the locking
lever to the left and gently pull the lower plate down).
When releasing the bayonet lock, the measuring device has to be held
tightly from below.
Loosen the set screw on the cone or plate and push the cone or plate bottom up, setting the shaft
length to the minimum.
Lift the coupling sleeve (red ring mark should be visible). Insert the cone or plate from below into
the measuring coupling. Lower the coupling sleeve (ring is covered) to attach the spindle.
Turn the adjusting screw on the plate down to the lowest position. Raise the plate to the top
position and secure it with the bayonet lock (position “closed”).
The actual distance between spindle and plate has to be adjusted to approximately 1 mm by
turning the adjusting screw up. Set the screw mark to “0” with approximately 1 mm between
cone and plate.
The dial indicator should also be set to mark “0” for distance control. Unlock the spindle shaft
to bring the spindle onto the plate, and tighten the cone set screw to fi x the shaft.
The plate is now adjusted to 50 μm. The adjustment ring lowers the plate down when turned
clockwise (looking down onto the adapter), and raises it up by turning the ring counter-clockwise.
Lower the plate to 0.5 mm by turning the adjustment ring clockwise for one complete revolution.
Now raise the plate, but not all the way back to the zero position; stop at the “5” mark in the ring
which sets the gap to 50 μm.
