4263B
Short
K
ey
The
Short
key
executes
the
SHORT correction
measurement to
obtain the
SHORT correction
data
(SHORT
impedance).
The
4263B
uses this
data to
cancel the
measurement errors
due
to
the
residual
impedance
of
the test
xture.
The data
is stored
in non-volatile
memory
(EEPROM).
The
SHORT
measurement
must
be done
with the
high and
low terminals
shorted
together
.
If
you
press
,
The
following
SHORT
correction
menu is
displayed when
is
pressed.
ShortMeas
|
Performs
the SHORT
measurement to
get
the
SHORT
correction
data.
MeasV
al
| Displays
the measured
SHORT correction
data.
When
MeasVal
is selected
and
is
pressed,
the 4263B
displays the
primary parameter
R
(resistance).
Then the
4263B
displays
the
secondary
parameter
X
(reactance)
when
is
pressed again.
Exit
|
Exits
the
SHORT correction
menu.
The
SHORT

is taken

WARNING:
Out

"
This
is
only
a
W
ARNING
message
,
so
the
SHORT
correction
data
will
still
be used.
SHORT
correction
data
is
saved
in
non-volatile
memory
(EEPROM),
and
is
cleared
when
4263B
is
reset.
It
is
not
cleared
when
the
*RST
command was
executed from
GPIB.
Y
ou
cannot
disable
the
Correction
function
using
the
front-panel keys
,but
you can
using the
GPIB
commands
.

Note
When performing transformer measurement (L2-N, L2-1/N, L2-M, or L2-R2),
the SHORT correction function does not work eectively
