Conguration
K
ey
The
Conguration
key
allows
you
to set
the beeper
mode,
choose the
power line
frequency and
to
execute
service
functions
and
the self-test.
Beep
|
Comparison
results
output
to the
beeper are
classied into
following modes:
OFF
Does
not
emit
a
beep (no
output to
beeper).
PASS
Emits
a
beep
when
the comparison
result is
IN.
FAIL
Emits
a
beep
when
the comparison
result is
HI, LO
,or
N.C..
(default)
Note
In
the
OFF
mode,
the
4263B
does
not
emit
a
beep
when
the
system
error
or
operation
error
occurs
.

After
the
test,
the
4263B
resets
the
instrument's
settings
.
EEPROM
T
ests
EEPROM.
The
data
stored
in
EEPROM
is
not
aected
when
no
error
is
detected.
If
errors
are
detected,
the
4263B
clears
the
data
and
restores
the
default
data.
Test
(Self-test)
|
The
self-test
tests
the
4263B
's
basic performance
and displays
the
results
as
the
sum
of
the
error
codes
of
each
existing error
.The
4263B
also
executes
its
self-test
when
it
is
turned
ON
(power-on
test).
The
settings
of the
4263B are
not
aected
by
the
self-test,
except
when
errors
occur
(See
below).
