B-23
Typical values for the 100 mA range:
smua.source.calibratei(-100e-3, -1e-30, -1e-6, -90e-3, -89.2e-3)
22. If this step is not on the CALA sense mode, send the measure calibration command using the
multimeter and 2606B readings, and range setting for the parameters:
smua.measure.calibratei(
-range, Z_rdg, DMM_Z_rdg, FS_rdg, DMM_FS_rdg
)
Where:
-range
= The negative of the present calibration range
Z_rdg
= The zero 2606B measurement
DMM_Z_rdg
= The zero DMM measurement
FS_rdg
= The FS 2606B measurement
DMM_FS_rdg
= The FS DMM measurement
Typical 100 mA range values:
smua.measure.calibratei(-100e-3, -1e-5, -1e-6, -91e-3, -89.2e-3)
23. Change connections as shown in the following figure.

24. Select the DMM DC volts function.
25. Repeat the above steps for the 3 A range. Compute the current reading from the DMM voltage
reading and characterized 0.5 Ω resistance value: I = V/R.
26. Select automatic polarity mode:
smua.cal.polarity = smua.CAL_AUTO
