Step 4
Mount the long stainless steel locator pin with the
reticule either on top or pointing downward into
the 3mm-hole at the end of the aluminum
positioning arm. Handle with care, as the tip is
quite sharp and may cause injuries.
Loosen the front screw on the POM-block. Slide
the positioning arm with the locator pin toward
the center of the tonearm body.
Now carefully pull the positioning arm towards
the pivot of the tonearm and place locator pin or
reticule right on the pivot of your tonearm. Many
tonearms have a small indentation indicating
where the exact pivot point is located.
This is ideal for precise positioning of the locator
pin on the pivot point.
Step 5
If you can spot the tonearm pivot, put the pinpoint
of the locator pin here. Many tonearms have a
small indentation indicating where the exact pivot
point is located. This is ideal for precise
positioning of the locator pin on the pivot point.
If there is no indication of the tonearm pivot
point, attempt to locate pin exactly over the
tonearm pivot center.
If unsure of pivot center, use the reticule to
visually determine tonearm pivot point by finding
symmetrical outer lines on the tonearm body.
Step 6
When the pivot point is determined and is
directly underneath the pin-point of the locator
pin, tighten thumb screw holding the positioning
arm in place.
Take care to NOT move the SMARTractor in
any way until the measurement of P2S valve is
finished.
The pinpoint has to be located precisely over the
pivot at all times during alignment.
You can fix the SMARTractor in place with clear
or painters blue tape by placing tape from the
SMARTractor to the side of the platter.
You can now read out the exact value on the
Vernier scale.
If unsure, please see page 6 for a short tutorial
how to read the Vernier scale correctly.
