5.2 Fundamentals
of
Operation
7.
Changing
the
range
(1)
When a recorder
is
connected
to
the
RECORDER
terminal,
set the range at a value about
1.2
times as much
as
the
expected maximum peak value. Maximum peak will be
about
80%
of the full scale ensuring that peaks remain
on
-
scale.
(2)
When
a
Chromatopac (integrator)
is
connected
to
the
RECORDER terminal
(lOmV terminal),
peaks
having
refractive index up to about
100
times as much
as
the setting
range can be recorded. Set the measurement range at
a
value
about
1/80
of the expected maximum peak refractive index.
Normally, the recorder range
is
set
at
a value
of
about from
1
to 10 and the plot full scale is adjusted by changing
AmN
on
the
Chromatopac side. The relationship
of
the
setting
range and attenuation of Chromatopac
(ATTEN)
for the plot
full
scale
when connected to the RECORDER terminal
(10mV) is
as
follows:
