Where:
-range
= The negative of the present calibration range
src_Z
= The -zero Series 2600B programmed source output value
DMM_Z_rdg
= The -zero DMM measurement
src_FS
= The -FS Series 2600B programmed source output value
DMM_FS_rdg
= The -FS DMM measurement
Typical values for the Model 2601B/2602B/2604B 1 V range:
smua.source.calibratev(-1, -1e-30, -1e-4, -0.9, -0.896)
Typical values for the Model 2611B/2612B/2614B/2634B/2635B/2636B 2 V range:
smua.source.calibratev(-2, -1e-30, -1e-4, -1.8, -1.805)
22. If this step is not on the CALA sense mode, send the measure calibration command using the
multimeter and Series 2600B readings and range setting for the parameters:
smua.measure.calibratev(
-range, Z_rdg, DMM_Z_rdg, FS_rdg, DMM_FS_rdg
)
Where:
-range
= The negative of the present calibration range
Z_rdg
= The -zero Series 2600B measurement
DMM_Z_rdg
= The -zero DMM measurement
FS_rdg
= The -FS Series 2600B measurement
DMM_FS_rdg
= The -FS DMM measurement
Typical Model 2601B/2602B/2604B 1 V range values:
smua.measure.calibratev(-1, -1e-4, -1e-6, -0.89, -0.896)
Typical Model 2611B/2612B/2614B/2634B/2635B/2636B 2 V range values:
smua.measure.calibratev(-2, -1e-4, -1e-6, -1.81, -1.805)
D. Be sure to complete each of the 22 steps of C for all six voltage steps in
Step sequence
(on page
B-22) before performing current calibration.
E. Select automatic polarity mode:
smua.cal.polarity = smua.CAL_AUTO
Step 3. Current calibration adjustment
A. Connect the Series 2600B SMU to the digital multimeter (see the following figure), and then
select the multimeter DC current function.
B. Send this command to initialize current calibration:
smua.source.func = smua.OUTPUT_DCAMPS
