volts
—
New
function
is
ac
volts:
a.
If
the
initial
and
new
functions are both
ac
volts (or
both
ac+dc
volts),
manual
ranging
mode
is
retained at
the
same
range, or autoranging
is
retained
(starting at
the
same
range).
b.
If
the
change
is
between
an ac
volts function (VA,
VA1, VA2) and
an
ac+dc
volts
function
(C,
Cl,
C2),
autoranging
is
automatically enabled.
c.
For
all
types
of
change
(ac to ac,
ac+dc
to
ac,
ac
to
ac+dc,
or
ac+dc
to
ac+dc), Averaging
mode
(extended
resolution)
and
all
other
modes
and values are
retained.
No sample change
is
allowed
in
any
8506A
ac volts function.
The
following
commands
are
used
when
initially

NOTE
AC
volts
function
commands
used
with the
8502A/AT
are
compatible
with the 8506A.
However,
the six
function
commands
mentioned above
allow
for
faster,
direct entry
into
the desired
8506A
ac
volts
mode.
If
the 85 06
A
is
already
in
an ac
volts function, an abbreviated
command
can be used when
selecting either of the other
two ac
volts functions.
When
selecting
between ac
or
dc coupling
for
ac
volts, the
full
command
string
mentioned
above must be
used.
The
abbreviated
commands
are as
follows:
1.
