Design Guide
B3.0
Verify the tolerances of the scale's mounting
surface given in the Interface Drawing.
B3.1
Verify the dimensions of the scale benching
edge (groove or straight edge) given in the
Interface Drawing.
B3.2
Calculate the length of PurePrecision ™ Tape Scale
required for your application using the formula
ML + 40 mm (ML - Measuring Length). Refer to
the Interface Drawing.
B3.3
In order to install the tape scale against a straight
edge, either the Applicator Tool or hands can
be used.
It is recommended to use the Applicator Tool for all
installations against a straight edge and highly
recommended for lengths greater than 250mm
(10 inches).
B3.4
In the case where the tape scale is to be installed
in a 6mm-wide groove, it has to be done by hand
only. The Applicator Tool is not compatible with a
6mm groove. Refer to the Interface Drawing.
B3.5
If machining the mounting surface is undesirable,
or not possible, a temporary straight edge can be
used that meets the dimensions and tolerances
specified in the Interface Drawing.
Section B - PurePrecision ™ Tape Scale Installation
Two kinds of temporary straight edge can be used -
• Type I -
Temporary Straight Edge of thickness
0.76 ± 0.05 mm (0.030 ± 0.002 inches).
Refer to the Interface Drawing for additional
dimensional requirements. A steel rule may be
one of the options for this type of temporary
straight edge.
NOTE:
The guide edge of the applicator tool (the edge
that comes in contact with the mounting surface
reference edge during installation of tape scale)
for this application is located on its bottom
surface. See Section B6.2 for further information.
• Type II -
Temporary straight edge with minimum
thickness 9.53mm (0.375 inches). Refer to the
Interface Drawing for additional dimensional
requirements.
NOTE:
The guide edge of the Applicator Tool for this
application is located on the outside surface.
See Section B6.2 for further information.
The tape scale will be offset from the temporary
straight edge for this application.
When using Type II temporary straight edge,
another temporary benching surface may be
required to install the index and limit markers
due to the offset.
