High

mode
specifies
asynchronous,
single trigger
mode
(T2).
The
previously selected trigger
mode
is
restored
once High Speed
mode
is
exited,
The
high

mode
("!")
cannot
be used
for
any ac

FUNCTION!
COMMAND
CHARACTERS
TheB505A
uses
the
same
function
command
characters as those
listed.
The
"C"
command
(decoupled
ac
volts)
can
only
be used
when
the
True-RMS
Converter
(Option ~08A)
is
installed.
When
an
8505A
function
is
changed,
the
multimeter
is
configured as
follows:
1.
If
the
same
function
is
re-selected,
the multimeter
assumes
autoranging and
retains
all
other existing
modes
and
stored values.
2.
If
a
new
function
is
selected,
the
following configuration
is
set:
a.
Autoranging
(R)
is
set.
b.
The
existing trigger
mode,
sample,
and
filter
are
retained.
However,
if
Average
mode
was
previously
on,
it
is
turned
off,
sample
is
set to
S7 and
filter
is
set to FO.
c.
Offset,
External
Reference,
Scaling,
Limits,
and Peaks
are
turned
off (PO,
XO,
UO
respectively),
with
all
respective
values
retained.
d.
Zero
mode
is
toggled
off
if
a
function other
than
dc
volts
(V)
or
ohms
(Z)
is
selected.
If
dc
volts
(V)
or
ohms
(Z)
is
reselected, the
Zero
mode
state
(on or
off)
is
restored
to that
in
effeetthe
last
time the
function
was
selected.
The
values
of
the
temporary zeros
are stored
until
the instrument
is
reset or
powered
off,
or
until
new
temporary zeros
are
stored.
e.
Calibration
mode
is
on
or
off
(as
determined by
the Calibration
Switch
setting)
and
gain correction
factors are
enabled
(MO).
When
an
8506A
function
is
changed,
the multimeter
assumes
a configuration defined
by
the
variety of
both
old
and
new
functions.
One
variety
includes
dc
volts
(V),
ohms
(Z),
and dc
amps
(I).
The
second
variety
includes
all
ac
volts
functions (VA,
VA1
,
VA2,
C,
Cl
,
and
C2).
Four
types
of
configuration
change
are therefore
possible.
Each
of
these
changes
resembles
that detailed
above
for
the
8505A,
with
the following exceptions:
1.
initial
function
was
V,
Z,
or
I
—
New
function
is
V,
Z, or
I:
The 8505A
configuration
is
used.
