Using SCPI:
Send the following code:
*RST
SENSe:FUNCtion "VOLT"
SENSe:VOLTage:RANGe:AUTO ON
SENSe:VOLTage:UNIT OHM
SENSe:VOLTage:OCOM ON
SOURce:FUNCtion CURR
SOURce:CURRent 5e-6
SOURce:CURRent:VLIM 10
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 commands:
Send the following code:
reset()
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.autorange = smu.ON
smu.measure.unit = smu.UNIT_OHM
smu.measure.count = 5
smu.source.func = smu.FUNC_DC_CURRENT
smu.source.level = 5e-6
smu.source.vlimit.level = 10
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
