Occasionally,
when

stylus
or
stylus
belt,
the zero
does not
print
at the same
place
near the
top
of
the chart
paper.
By rotating
the
BOTTOM ZOOM
control
counter-clockwise the
zero line can be
moved towards
the
top
of
the chart
paper,
clock-
wise rotation
moves the zero line
towards
the
bottom
of the
paper.
The control
has been
designed
so that even if the
record
goes
off
the bottom
of the
paper,
it- can
still be
adjusted
to
print
on the
paper.
The ZERO
ADJUST control
will function if
the BOTTOM
ZOOM feature is on
or off.
Pressing
the Marker button
causes
a vertical line to
be
printed
on the
paper.
Hold the
Marker
button down and the unit
will
print
the vertical line for
as
long
as the button is held down.
