5. Allow the readings to settle, then get both the multimeter and 2601B-PULSE current readings at the
positive zero value (the 2601B-PULSE measurement is not necessary if this step is being done on the
CALA sense mode). The two measurements should be made as close as possible in time. Use this
command for the 2601B-PULSE:
Z_rdg = smua.measure.i()
6. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
7. Set the source output to the positive full-scale value for the present range, for example:
smua.source.leveli = 90e-3
8. Turn on the output:
smua.source.output = smua.OUTPUT_ON
9. Allow the readings to settle, then get both the multimeter and 2601B-PULSE current readings at the
positive full-scale output value (the 2601B-PULSE measurement is not necessary if adjustment is being
done on the CALA sense mode). The two measurements should be made as close as possible in time.
Use this command for the 2601B-PULSE:
FS_rdg = smua.measure.i()
10. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
11. 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
= The present adjustment range
src_Z
= The +zero 2601B-PULSE source output value
DMM_Z_rdg
= The +zero DMM measurement
src_FS
= The +FS 2601B-PULSE source output value
DMM_FS_rdg
= The +FS DMM measurement
Typical values for the 100 mA range:
smua.source.calibratei(100e-3, 1e-30, 1e-5, 90e-3, 88e-3)
12. If this step is not on the CALA sense mode, send the measure calibration command using the
multimeter and 2601B-PULSE readings, and range setting for the parameters:
smua.measure.calibratei(range, Z_rdg, DMM_Z_rdg, FS_rdg, DMM_FS_rdg)
Where:
range
= The present adjustment range
Z_rdg
= +zero 2601B-PULSE measurement
DMM_Z_rdg
= The +zero DMM measurement
FS_rdg
= +FS 2601B-PULSE measurement
DMM_FS_rdg
= The +FS DMM measurement
Typical 100 mA range values:
smua.measure.calibratei(100e-3, 1e-6, 1e-5, 0.089, 0.088)
13. Select negative polarity, then set the source output to the negative zero value, for example:
smua.cal.polarity = smua.CAL_NEGATIVE
smua.source.leveli = -1e-30
