The UNI-Protractor is a versatile alignment and
positioning instrument for use with phono
tonearms and cartridges. It allows precise
alignment of any given tonearm to any tangential
curve desired.
Furthermore the user can determine whether a
given mounted tonearm does meet any correct
calculated tangential curve – i.e. whether it is
correct mounted or aligned.
This applies to all tonearms – no matter what
effective length, mounting distance or specific
geometry a given tonearm may ask for.
The user can measure, align and determine
all positioning parameters related to the
geometrical/mechanical alignment of a cartridge-
tonearm combination.
The UNI-Protractor set consists of the
following parts:
− the UNI-Protractor metal main frame with the
micrometer linear drive
− 3 POM tt-spindle adapters for diameters 7.10,
7.15 and 7.20 mm
− clear acrylic positioning arm for mounting
distance 8“ - 14“
− 1 locator to be mount in positioning arm –
1 round reticle - with white haircross
lines
− metal frame magnifier
− a selection of 3 mm mirrored parallax templates
for tangential curve alignment
− clear acrylic 8 mm vertical azimuth template
−
overhang gauge
− stainless steel metric ruler w/.5mm scale to
determine the mounting distance P2S
−
cold light LED lamp
A brief introducton
!
Please check your UNI-Protractor set. All the
above parts must be included to ensure perfect
function.
Each UNI-Protractor was carefully checked and
tested prior to shipment.
Please do get yourself familiar to the handling and
use of the UNI-Protractor.
While it is a mechanical positioning instrument, it
needs a minimum of attention to detail by the user
to obtain the maximum precise results it ensures if
handled correctly.
To get access to all possible features of the UNI-
Protractor it is inevitable to read this manual.
But most important please study the step-by-step
pictured instruction to learn how to set-up the
UNI-Protractor correctly.
Attention
Due to the very tight tolerances - some are indeed
tight fit – some parts of the UNI-Protractor have
to be put in place in a certain sequence. These
tight tolerances are mandatory to achive true
precision. When you receive the UNI-Protractor,
make sure to give it enough time to adapt to room
temparature.
This is important for perfect function.
DISCLAIMER
Please use all parts with care -
especially when your cartridge sits
on the template.
The azimuth template is particular
sensitive to fall due to mechanic shock.
The use of the UNI-Protractor is on
your own risk. The manufacturer and
the designer do not take any respon-
sibility for damage due to operate or
handle the
UNI-Protractor or any of it’s parts.
Keep out of reach of children !!
