Turn on the POWER switch and
the
OUTPUT switch.
Short the
output terminal
and
adjust
the semi
-fixed potentiometer on
the front
panel
so that the
required output
cnirrent
Is
obtained when
E2
is 10 V,

The relationships between
the
output current
(lo)
and
the
external
control voltage
signal
(E2)
are expressed as follows:

Term
B
is
a
factor
which
is
determined by
the
CURRENT
setting potentio-
meter,
for
a
range
of 0 -
1.
When
the
CURRENT setting potentiometer
(including the
FINE
CURRENT setting potentiometer
if the
FINE VOLTAGE
potentiometer
has
been modified
to it)
is
turned
to
the
clockwise
extreme position,
B
is
1;
when
it is
turned
to
the
counterclockwise
extreme position,
B
is
0-
With this factor,
the
ratio
of the
output
current
(lo)
with respect
to the
external control voltage signal
(E2)
can be adjusted.
Note.
1:
The potential of
the
common line
of the
external control
voltage signal
(E2)
becomes
that
of the
"+" OUTPUT terminal.
