Section 3: Basic Operation Series 2600A System SourceMeter® Instruments Reference Manual
1. Press the CONFIG key then press MEAS. Choose V-MEAS, and then press ENTER or the
navigation wheel.
2. Select SENSE-MODE, then press ENTER.
3. Choose 2-WIRE or 4-WIRE, as desired, and then press ENTER or the navigation wheel.
Remote sense selection
Use the smuX.sense command to control sense selection by remote. For example, send this
command to enable 4-wire sensing:
smua.sense = smua.SENSE_REMOTE
See Table 3-6 and Section 19 for details.
Remote ohms programming
The following paragraphs summarize basic commands necessary for remote ohms programming
and also give a programming example for a typical ohms measurement situation.
Remote ohms command
Use the following command to obtain a resistance reading:
reading = smuX.measure.r()
See Table 3-6 for more commands necessary to set up source and measure functions, and
Section 19 for more details.
Ohms programming example
The set-up and command sequence for a typical ohms measurement is shown below:
• Source function: current, 10mA range, 10mA output
• Voltage measure range: auto
• Voltage compliance: 10V
• Sense mode: 4-wire
-- Restore Series 2600A defaults.
smua.reset()
-- Select current source function.
smua.source.func = smua.OUTPUT_DCAMPS
-- Set source range to 10mA.
smua.source.rangei = 10e-3
-- Set current source to 10mA.
smua.source.leveli = 10e-3
-- Set voltage limit to 10V.
smua.source.limitv = 10
-- Enable 4-wire ohms.
smua.sense = smua.SENSE_REMOTE
-- Set voltage range to auto.
smua.measure.autorangev = smua.AUTORANGE_ON
-- Turn on output.
smua.source.output = smua.OUTPUT_ON
-- Get resistance reading.
print(smua.measure.r())
-- Turn off output.
smua.source.output = smua.OUTPUT_OFF
