3. Perform each calibration step listed in Table 16-2 (Model 2601/2601) or
Table 16-3 (Model 2611/2612) as follows:
a. Select the range being calibrated with this command:
smua.source.rangev = range
(Note that it is not necessary to set the measure range for calibration.)
For example, for the Model 2601/2602 1V range, the following
command would be sent:
smua.source.rangev = 1
For the Model 2611/2612 2V range, the following command would be
sent:
smua.source.rangev = 2
b. Select the correct sense mode based on the calibration step from Table
16-2 or Table 16-3, for example:
smua.sense = smua.SENSE_LOCAL
c. Select positive polarity, then set the source output to the positive zero
value:
smua.cal.polarity = smua.CAL_POSITIVE
smua.source.levelv = 1e-10
d. Turn on the output:
smua.source.output = smua.OUTPUT_ON
e. Allow the readings to settle, then get both the multimeter and Series
2600 voltage readings at the positive zero value (the Series 2600
measurement is not necessary if this calibration 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 Series 2600:
Z_rdg = smua.measure.v()
f. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
g. Set the source output to the positive full scale value for the present
range, for example:
smua.source.levelv = 0.9 (Model 2601/2602)
smua.source.levelv = 1.8 (Model 2611/2612)
h. Turn on the output:
smua.source.output = smua.OUTPUT_ON
i. Allow the readings to settle, then get both the multimeter and Series
2600 voltage readings at the positive full-scale output value (the Series
2600 measurement is not necessary if this calibration 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 Series 2600:
FS_rdg = smua.measure.v()
j. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
