and
then
the

In

one
side
of
the

is
connected
to
H

terminals
,
and
the
other

When
measuring
N,
the
4263B
measures
both
voltages
at
H
CUR
(V1)
and
at
H
POT
(V2),
while
applying
an
A

voltage
to
H

measurements
,
SW1
switches
(in
Figure

to
H
CUR
and
H
POT
.
The
4263B
calculates
N
from
the
ratio
of
these
two
voltages
.
When
measuring
M,
the
4263B
measures
the
voltage
at
H
POT
(V2)
and
the
current
input
to
L
CUR
(I1).
The
4263B
calculates
M
from
the
ratio
of
V2
and
I1.
Note
The
4263B
can
only
measure
N
1.
So
,
to
measure
N,
connect
the
transformer
side
with
the
more
turns
to
the
H
CUR
terminal.
Note
The
conguration
shown
in
Figure
3-11
is
a
two-terminal
conguration,
while
the
4263B 's
normal
measurement

is
a
four-terminal
