Voltage
Measurement
in
Channel
A
By
pressing
button
A
26,
the
voltage
in
channel
A and
the
phase
angle
between
channels
A
and B,
referred
to
channel
A,
are
measured.
The
phase
is
measured
as
absolute
phase
(21
or
2£
pressed)
or
relative
to
a
reference
value
(22
or
£4
pressed)
and
indicated
in
degrees.
The
following
voltage
indication
modes
can
be
selected:
a)
absolute
linear
indication
in
mV
by
pressing
button
LIN.
21
b)
linear
indication
referred
to
a
reference
value
by
pressing
button
LIN. REF.
22
c)
absolute
logarithmic
indication
in
dEm
by
pressing
button
LOG.

d)
logarithmic
indication
in
dB
referred
to
a
reference
value
by
pressing
button
LOG.

B
25,
the
voltage
in
channel
B
and
the
phase
angle
between
channels
A
and B,
referred
to
channel.
A,
are
measured.
The

For
voltage
indication
and
voltage
and
phase
reference
values
the

the
voltages
in
channel
A
and in
channel
B and
the
phase
angle
between
channels
A
and B,
referred
to
chaimel
A,
are mea-
sured.
Hie
phase
is
measured
as
absolute

or
relative
to
a
reference
value
(
22
