Using SCPI commands:
To change to 2-wire sensing for current measurements, send the command:
:SENSe:CURRent:RSENse OFF
To change to 2-wire sensing for voltage, replace
CURRent
with
VOLTage
. For resistance, replace
CURRent
with
RESistance
.
Using TSP commands:
For voltage measurements, send the commands:
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.sense = smu.SENSE_2WIRE
To assign a different measure function, replace
smu.FUNC_DC_VOLTAGE
with one of the following:
•
For current measurements:
smu.FUNC_DC_CURRENT
•
For resistance measurements:
smu.FUNC_RESISTANCE
