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 virtual 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.

smu

X

.measure.rel.enabler = smu

X

.REL_ON 

Enable resistance relative 
offset 

smu

X

.measure.rel.enablev = smu

X

.REL_ON

* smu

X

 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
