To establish a unique relative offset value from the front panel:
1. Press the
CONFIG
key and then the
REL
key.
2. Select the measurement function (
CURRENT
,
VOLTAGE
,
OHMS
, or
WATTS
), and then press
ENTER
or the
navigation wheel
. The present relative offset value is displayed.
3. Set the relative offset value.
4. With the relative offset value displayed, press the
ENTER
key or the navigation wheel
, and
then press the
EXIT (LOCAL)
key to back out of the menu structure.

Relative offset commands
Relative offset commands are summarized in the following table.
Relative offset commands
Command*
Description
To set relative offset values:
smu
X
.measure.rel.leveli = relval
Set current relative offset value
smu
X
.measure.rel.levelp = relval
Set power relative offset value
smu
X
.measure.rel.levelr = relval
Set resistance relative offset
value
smu
X
.measure.rel.levelv = relval
Set voltage relative offset
value
To enable/disable relative offset:
smu
X
.measure.rel.enablei = smu
X
.REL_OFF
Disable current relative offset
smu
X
.measure.rel.enablep = smu
X
.REL_OFF
Disable power relative offset
smu
X
.measure.rel.enabler = smu
X
.REL_OFF
Disable resistance relative
offset
smu
X
.measure.rel.enablev = smu
X
.REL_OFF
Disable voltage relative offset
smu
X
.measure.rel.enablei = smu
X
.REL_ON
Enable current relative offset
smu
X
.measure.rel.enablep = smu
X
.REL_ON
Enable power relative offset
smu
X
.measure.rel.enabler = smu
X
.REL_ON
Enable resistance relative
offset
smu
X
.measure.rel.enablev = smu
X
.REL_ON
Enable voltage relative offset
*
smu
X
: For Models 2601B, 2611B, and 2635B, this value is
smua
(SMU Channel A); for Models
2602B, 2604B, 2612B, 2614B, 2634B, and 2636B, this value can be
smua
(for SMU Channel A) or
smub
(for SMU Channel B).
Relative offset programming example
The programming example below performs a current measurement, uses it as the relative offset
value, and also enables current relative offset:
-- Measure and set present current value as the relative offset.
smua.measure.rel.leveli = smua.measure.i()
-- Enable current relative offset.
smua.measure.rel.enablei = smua.REL_ON
