Measure resistance using the resistance function
When the measurement function is set to resistance, the Model 2461 measures resistances by
sourcing current. The instrument automatically sets the magnitude of the current source, voltage limit,
and the measure range.
This mode is the same as the Ohmmeter Quick Setup, which is available by pressing the QUICKSET
key.
The examples below use a 100 k
Ω
device under test. The code makes five readings. Note that the
measurement range is 200 k
Ω
.
Using SCPI:
Send the following code:
*RST
SENSe:FUNCtion "RES"
SENSe:RESistance:RANGe:AUTO ON
SENSe:RESistance:OCOMpensated ON
SENSe:COUNt 5
OUTPut ON
TRACe:TRIGger "defbuffer1"
TRACe:DATA? 1, 5, "defbuffer1", SOUR, READ
OUTPut OFF
The front-panel display will look similar to the following example.

Using TSP:
Send the following code:
reset()
smu.measure.func = smu.FUNC_RESISTANCE
smu.measure.autorange = smu.ON
smu.measure.count = 5
smu.source.output = smu.ON
smu.measure.read(defbuffer1)
for i = 1, defbuffer1.n do
print(defbuffer1.relativetimestamps[i], defbuffer1[i])
end
smu.source.output = smu.OFF
