TIME
POSITION (used
with
DM44)-
0perates in the
same
manner
as
42a. In addition,
when the
DM44
is
in the
TIME

this
control
operates
in
conjunction
with
the
D.
TIME
control. The
DELAY

both the reference
point
and the time-measurement
point,
while the
D.

only
the
time-measurement
point.
With the time-measurement
point
to
the
left
of
the reference
point
the Readout
indicates a negative
time
difference.
NOTE
The
DM44
may be
modified
to make the
DELAY
TIME POSITION
control
move
only
the reference
point.
The
procedure
for
making this modification
is
located in the Maintenance Section
of
the DM44
Instruction Manual. Modification
is
to be done
by
qualified service personnel only.
