recorded high
and low
values.
A
multimeter
function
change
disables
Peak
mode
and
retains
peak
values.
At
any
time, reentry into the
Peak
mode
(toggle
PEAK
again)
erases
previously recorded
values.
Both Peak
mode
and peak
values are
lost
during
a
Power-Up
or
Reset condition.
2-119.
LIMITS
2-120.
The
Limits
mode may
be
employed
to display a
pass-fail
indication of
measurement
values.
The
mode
is
entered
when
a
single
high or
low
limit
value
is
stored, or
when
the
LIMITS
button
is
pushed.
A
second
store
sequence must be used
if
both
high
and
low
limits
are
desired.
Either the regularly displayed value
or
programmed
numerics
may
be used
for the
limit
values.
For
example, high
and low
limits
of 12.05 and
11.95
would
be
programmed
as follows:
STORE
1
2
.
0
5
HI
STORE
1 1
.
9 5
LO
In
this
example, the
multimeter
enters the Limits
mode
when
either the
HI
or
LO
button
is
first
pushed.
Mode
entry
is
verified
by a display of HI,
LO,
or
PASS.
In
this
case,
readings higher
than
12.05 yield a
HI
display,
readings lower
than
1
1
.95
yield
LO, and
all
other read
ings
yield
PASS. The
limit value(s) are
compared
to the
now
transparent display reading with
all
other parameters and
operations
still
in effect.
2-121.
A
display
reading can
also be stored as a
limit
value.
Use
the following sequence:
STORE
HI
(or
LO)
2-122.
Use of Limits
mode
does not
interrupt other uses
of the
multimeter.
No
measurement parameter
or
mathematic operation
is
changed:
The
other special
operation (Peak)
may
be used simultaneously with Limits
mode.
Any
of the
measurement parameters
or operations
may
be enabled,
changed, or
recalled
while
in
the
Limits
mode:
the
display responds
in
the standard fashion during
this
process
and
automatically
reverts to limits
indications
once
the process
is
complete. Limits values
may
be
recalled at
any time (Limits
mode
enabled or
disabled).
The
recall
sequence does not change
the state of
the Limits
mode.
The
following
recall
sequence
is
used:
RECALL
HI
LIMITS
RECALL
LO LIMITS
The
recalled
value
is
latched
in
the display as
long
as
the
LIMITS
button
is
held depressed.
2-123. Pushing
the
LIMITS
button
toggles the
multimeter
into
or out of
the
Limits
mode
whether
or not
limits
values
have been
entered.
A
function
change
disables the
Limits
mode,
but
retains
any
existing
limit
values.
Once
stored, limits
values are retained during
all
but
Power-Up and
Reset sequences.
2-124.
Remote
Control
2-125.
The
multimeter
may
be
equipped with any
of
three
remote
interface
modules.
These modules
are
fully
explained
in
Section
6.
When
the
IEEE Remote
Interface
(Option
05)
is
installed,
the front panel
LCL/RMT
push
button
can
be used
to
enable
local control,
but cannot be
used
to
enable remote
control.
Remote
control can only
be
commanded
from
the
remote
location with
this
interface.
2-126.
The
LCL/RMT
push button
may
be used
to
toggle into/
out of remote
control
when
either the
Bit
Serial
Remote
Interface
(Option
06)
or the
Parallel
Remote
Interface
(Option
07)
is
installed.
Whenever
the
multimeter
is
in
remote
control,
whether
commanded
locally
or
from
the remote, the
REMOTE
annunciator
is
lighted.
2-127.
When
in
remote, only the
POWER
push
button
remains operational
in
all
circumstances.
The
LCL/RMT
push button
may
remain operational, but
is
disabled
by
a
local
lockout or
display off
command
from
the
remote
(refer
to Section
6).
A
power
interruption,
whether
caused
by
line failure
or toggling of the
power push
button,
returns the
multimeter
to local control.
2-128. Calibration
Mode
2-129.
DESCRIPTION
2-130.
The
rear
panel
calibration
switch
is
used
to
enable or disable the Calibration
mode
(remove
calibration
seal for access).
The
AVG/(CAL)
annunciator flashes
when
the Calibration
mode
is
enabled, or
is lit
steadily
when
the
Averaging
mode
is
enabled.
Regular multimeter operation
is
significantly
altered
while
in
the Calibration
mode:
1.
Power
must
not be cycled on or
off
when
the
Calibration
mode
is
activated (rear panel
Calibration Switch
on).
2.
Overrange
conditions
no
longer cause
a special
flashing
"HHHHHH"
indication.
3.
Underrange
conditions
in
V
AC
functions
no
longer cause a "flashing
L"
indication.
4.
Averaging
mode
is
locked
out:
the Calibration
and Averaging modes
are
mutually
exclusive.
However,
pushing
the
AVG
button
when
Calibration
mode
is
on
does enable or
disable
latching error
indications.
5.
All
mathematic
operations
and
special
operations are disabled.
6.
7-1/2
digits
are displayed
on 10V
dc range and
6-1/2
digits
are displayed
on
all
other functions and
ranges.
A
sign
(±) is
displayed
for
all
functions to
facilitate
potentiometer adjustment.
