Section 17: Calibration
21. Send the source calibration command using the -range, -zero and -FS multimeter readings, and
-zero and -FS source values for the parameters:
smua.source.calibratei(-range, src_Z, DMM_Z_rdg, src_FS, DMM_FS_rdg)
Where:
-range
src_Z
DMM_Z_rdg
src_FS
DMM_FS_rdg
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
Z_rdg
DMM_Z_rdg
FS_rdg
DMM_FS_rdg
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.
