MEMORY COMMAND

STORE
Commands
KO
(store
dc
volts
zero)
and
K1
(store
ohms
zero)
can be used
with
either
the
8505A
or the
850SA,
However,
the zero value
is
stored
in
the following
new
fashion:
1. If
Calibration
mode
is
on (G5 response
~
1),
any
zero value entered with
the
KOorKI
command
is
stored
directly
in
the Calibration
Memory
and retained
until
a
new
value
is
stored during Calibration
mode
on.
Software
calibration
uses
this
procedure and
is
fully
described
in
Appendix
7B.
2.
if
Calibration
mode
is
off
(G5 response
=
0),
any
zero value entered with the KO
or
K1
command
is
stored
in
a
separate, temporary
memory. These
values
do
not
affect
the values stored
in
Calibration
Memory. The
temporary
zero values are retained
and
applied
to
subsequent readings
until
the multimeter
is
powered-off or
reset.
The
temporary zero values
are
all
reset to 0
at
power-up
or reset.
3.
Whenever
the
KO
or
K1
command
is
used (Calibration
mode
on
or
off),
a separate zero value can be stored
for
each
range.
a.
If
Calibration
mode
is
on, the zero value
is
stored
for
the range selected without
affecting the
value
for
any
other range.
b.
If
Calibration
mode
is
off,
any
zero value stored
is
applied tothe
existing
range and
all
higher
ranges
in
the
same
function. Therefore, separate values
for
each
range can be entered by
using
KO
(or
K1
The
following additional store
commands
are available for the
8505A
or the 8506A:
1.
K
N
G
:
Keep
gain correction
on
this
range. This
command
is
used when
storing calibration
gain
correction factors with Calibration
mode
on.
Software
Calibration
(Appendix
78) deals with
this
procedure
in detail,
2.
KND:
Keep
the following
six digits
as the
calibration
date or the multimeter
identification.
Any
value
totaling
999999
or
less
can be
entered
(with
Calibration
mode
on).
Zeros are not suppressed
if
less
than
six
digits are entered.
The
full
procedure
is
defined
in
Software
Calibration
(Appendix
7B).
3.
K
3
:
Keep
the error
response message.
This
command
allows the operator
to
specify the response
for
an
error condition.
These
characters
(instead
of
the
actual reading) are
then automatically returned
whenever
an error condition occurs. For example,
the
word
ERROR
or an obviously
illegal
response
value (such as 1E20) can be
programmed
as the
error
response message.
The
desired response
must
be
reprogrammed
after a
power-up
or reset condition occurs.
The
multimeter
returns 0 as the error
message
if
no
other
message
has
been programmed. The
actual error
can
only
be
identified
as the
first
and second
characters
of
the
G1
(Get Status) response.
The
following
rules
must
be followed
when
making
the
K3
entry:
a.
A maximum
of
any
15 characters (excepting immediate and
termination characters)
can be
programmed
following the
K3 command.
Spaces can be used
as
part of
the 15 character
total.
Characters
in
excess
of 15 are ignored by
the
multimeter and do
not
cause an
error condition.
b.
Nulls are
discarded
and
not stored. Nulls are not
counted
for
the 15 character
limit.
c.
Any
immediate character (including
termination characters) terminates
and
executes the
string
normally.
d.
The
$
command
is
an immediate
character only
when
used
with the
Bit
Serial Interface (Option
-
06).
With
the
IEEE-488
Interface (Option
-05) or Parallel Interface
(Option
-07), $
