Set
the
controls
as
follows:
HORIZONTAL
0.1
BASE
VOLTS
VERTICAL
100
COLLECTOR
MA
STEP SELECTOR

MA/STEP
POLARITY
MINUS
Connect
a
1
K
precision
resistor
between
terminals
B
and
E
on
the
right
side
of
the
test
panel
and
move
the
lever
switch
to
the
TRANSISTOR
B position.
There
should
now
be
a
display
of
approximately
one
dot
per
ten
major
divisions.
Check
the
distance
between the
dots
and
turn
POLARITY
switch
to
the
plus
position. With
the +Step
Adj.,
move
the
dots
so
that
the
same
spacing
as
the
minus
position
is
obtained.
With
the
+Step
Adj.
it
will
be
possible
to
maintain
the
same
amount
of
voltage
per
step
in both
the
plus and
minus
positions
of the POLARITY
switch.
The
standardizing
is
measured
in
the
1
MA/STEP
position
of
the
STEP
SELECTOR
with
a
1
K
resistor
from
the
Step
Amplifier to
ground.
