Series 2600 System SourceMeter® Instruments Reference Manual Section 16: Calibration
13) If this step is not on the CALA sense mode, send the measure calibration command
using the multimeter and Series 2600 readings, and range setting for the
parameters:
14) smua.measure.calibratev(range,Z_rdg,DMM_Z_rdg, FS_rdg,DMM_FS_rdg)
Where: range present calibration range
Z_rdg +zero 2600 measurement
DMM_Z_rdg +zero DMM measurement
FS_rdg +FS 2600 measurement
DMM_FS_rdg +FS DMM measurement
Typical Model 2601/2602 1V range values:
smua.measure.calibratev(1,1e-4,1e-5,0.92,0.903)
Typical Model 2611/2612/2635/2636 2V range values:
smua.measure.calibratev(2,1e-4,1e-5,1.82,1.802)
15) Select negative polarity, then set the source output to the negative zero value, for
example:
smua.cal.polarity = smua.CAL_NEGATIVE
smua.source.levelv = -1e-10
16) Turn on the output:
smua.source.output = smua.OUTPUT_ON
17) Allow the readings to settle, then get both the multimeter and Series 2600 voltage
readings at the negative 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()
18) Turn off the output:
smua.source.output = smua.OUTPUT_OFF
19) Set the source output to the negative full scale value, for example:
smua.source.levelv = -0.9(Model 2601/2602)
smua.source.levelv = -1.8(Model 2611/2612/2635/2636)
20) Turn on the output:
smua.source.output = smua.OUTPUT_ON
21) Allow the readings to settle, then get both the multimeter and Series 2600 voltage
readings at the negative 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()
22) Turn off the output:
smua.source.output = smua.OUTPUT_OFF
23) Send the source calibration command using the range, -zero and -FS multimeter
readings, and -zero and -FS source values for the parameters:
smua.source.calibratev(-range,src_Z,DMM_Z_rdg,
src_FS,DMM_FS_rdg)
Where: -range negative of the present calibration range
src_Z -zero 2600 source output value
DMM_Z_rdg -zero DMM measurement
src_FS -FS 2600 source output value
DMM_FS_rdg -FS DMM measurement
Typical values for the Model 2601/2602 1V range:
smua.source.calibratev(-1,-1e-10,-1e-4,-0.9,-0.896)
