Digit 8
is
used only
on
the
10V dc range
to yield IVz digit resolution.
On
all
other ranges
and
functions,
6%
digit
resolution
is
used and
digit
8
is
set to
0.
OFFSET
COMMAND
CHARACTERS
When
storing
the previous reading as an
offset,
both the
8505A
and
the
8506A
use
the displayed value
in
the
same
manner
as does the 8502A.
LIMITS
AND
PEAKS
COMMAND
CHARACTERS
When
Limits testing
is
enabled
(U),
an
error
is
identified
by
either of the following responses:
1.
The
standard
error
response message (programmed
with the
K3 command)
is
normally
returned.
2.
If
no such standard
error
response
message
has been
programmed
sincethe
last
power-up
or
reset,
a
"2"
is
returned
to identify
an
error
occurring during
limits testing.

ASCII Data Output Format
Digit 7
is
used with the
8505Aand 8506A whenever
6V2 digits
of resolution are
available.
If
5V2 digits
are
available, digit
7
is
not
needed and
is
consequently
set to
0.
CALIBRATION
CONSTANT
The
Calibration
Memory
is
a standard
feature
of
the
8505A and
8506A. Therefore,
the
M
and
MO
commands may
be used
at
any
time
to inhibit or
enable
all
Calibration
Memory
gain correction
factors:
M:
inhibit
all
calibration
gain correction
factors.
,
MO: enable
calibration gain correction
factors.
The Ml and
M2
commands may
be used
to inhibit
or enable the
temporary zero correction factors stored with the
K0 and
K1
commands
(V
DC
and
OHMS
only).
This
has
the
same
effect
as turning the
Zero mode
off
and on
with the
ZERO
push
button,
except
the
M2
command
does not store zeros;
Ml:
inhibit
zero correction values
(turn
Zero
mode
off).
M2: enable zero
correction values
(turn
Zero
mode
on).
The temporary zero
correction factors are applied
in
dc
volts (V) or
ohms
(Z)
whenever
the
M2 command
is
in
effect
(i.e.,
whenever Zero mode
is
on).
When
the multimeter
is
powered-up
or reset, the
Zero
mode
is
turned
on and
the
temporary
zero correction factors are reset
to
0.
During normal operation
(Calibration
mode
off),
the
"permanent"
zero correction
factors
in
Calibration
Memory
are
always
in
effect,
and
are not affected by the
Ml
and
M2
commands.
Calibration
Memory
allows
for
software
calibration of
all
functions
and
is fully
described
in
Appendix
7B. Although
software
calibration
procedures
are not discussed here, the following
considerations must be observed
if
Calibration
mode
is
turned
on
(the Calibration
mode
is
enabled
or
disabled with the rear panel Calibration Switch
when
the
multimeter
is in
local control):
1.
Calibration correction factors are
always applied
to
readings unless
the
M
command
is
sent. This
is
true
whether
Calibration
mode
is
on
or
off.
2.
When
Calibration
mode
is
on, the
Ml and
M2 commands
enable
and
disable the "permanent"
zero
correction factors stored
in
Calibration
Memory. Temporary
zeros are
not
used
in
Calibration
mode.
3.
When
Calibration
mode
is
on, the resolution available
for
each range
and
function
is
the
same
as
for
Average
mode
(refer
to
RANGE
COMMAND
CHARACTERS).
