Measurement
made
using
"EIA
Linearity
Chart"
in
accordance
with
RS-37sA.
If
measured on a
field
of
characters,
the
character
height
and
width
are
within
10%
of
that
for
any
adjacent
character
and
within
20%
of
that
for
any
character
on
screen
Perimeter
Non-Rectangularity
- The
perimeter
of
a
full
field
of
characters
approaches
an
ideal
rectangle
of
4 by 3
aspect
ratio
to
within
±l.s%
of
the
rectangle
height.
