Reading the

vernier scale

The SMARTractor features a Vernier scale to al-

low precise read-out of the P2S with an accuracy

of 5/100 mm.

This Vernier scale runs right to left - as does the

metric scale with increasing distance of P2S.

If you are unfamiliar with a Vernier scale, please

get accustomed to its operation.

The white numbers 1- 9 over the black back-

ground are 1/10 of a mm each. The white lines

between numbers are 0.5/10 mm each - or 5/100

mm each.

Whenever any of the white lines is absolutely in-

line with a black line on the aluminum scale, then

it denominates the 5/100 value which has to be

added to the full mm value given between the

2 white "leaves" centered by the full vertical

white line on the left of the scale just before the

half-circle end.

To illustrate the read-out procedure, here are a

few examples of mounting distances for common

tonearms.

One will become accustom quite quickly to this

way of

reading the scale.

The Vernier scale is an international standard in

industrial precision analog measuring.

This is 295,00 mm P2S - suitable for a FR-66s.

231.5 mm P2S - the white "5" being in line.

Perfect mounting distance for the FR-64s.

The magnifier

Using the Glass Magnifier greatly increases the

visibility of the stylus when trying to align on

the single spot. It further also allows with most

modern cartridges to get a fairly good view of the

cantilever.

Place the magnifier in the cut-out frame on the

clear acrylic positioning arm and pull it all the

way forward so that it seats squarely against the

clear acrylic.

It is automatically in a position to optimize focus

when viewing through the glass lens on the

alignment spot for the selected tangential curve.

The cutout for the Glass Magnifier in the

acrylic positioning arm allows for adjusting the

side-to-side position of the Glass Magnifier to

accommodate all different positions of the 5

tangential curves on the SMARTractor.
