Defining a relative offset value
A unique relative offset value can be established for the selected measurement function.
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.
Remote relative offset programming
Relative offset commands
Relative offset commands are summarized in the following table.
Relative offset commands
Command
Description
To set relative offset values:
smua.measure.rel.leveli = relval
Set current relative offset value
smua.measure.rel.levelp = relval
Set power relative offset value
smua.measure.rel.levelr = relval
Set resistance relative offset value
smua.measure.rel.levelv = relval
Set voltage relative offset value
To enable/disable relative offset:
smua.measure.rel.enablei = smua.REL_OFF
Disable current relative offset
smua.measure.rel.enablep = smua.REL_OFF
Disable power relative offset
smua.measure.rel.enabler = smua.REL_OFF
Disable resistance relative offset
smua.measure.rel.enablev = smua.REL_OFF
Disable voltage relative offset
smua.measure.rel.enablei = smua.REL_ON
Enable current relative offset
smua.measure.rel.enablep = smua.REL_ON
Enable power relative offset
smua.measure.rel.enabler = smua.REL_ON
Enable resistance relative offset
smua.measure.rel.enablev = smua.REL_ON
Enable voltage relative offset
Relative offset programming example
The programming example below performs a current measurement, uses it as the relative offset value,
and 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
