s. Allow the readings to settle, then get both the multimeter and Series
2600 current 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()
t. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
u. 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 = 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 1A range:
smua.source.calibratei(-1,-1e-10,-1e-5,-0.9,-0.892)
v. 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:
smua.measure.calibratei(-range,Z_rdg,DMM_Z_rdg,
FS_rdg,DMM_FS_rdg)
Where: -range = negative of the 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 1A range values:
smua.measure.calibratei(-1,-1e-4,-1e-5,-0.91,-0.892)
Be sure to complete steps a through v for the 100nA to 1A ranges before
continuing with 3A and 10A range calibration (Model 2601/2602) or 1.5A
and 10A range calibration (Model 2611/2612).
Change connections as shown in
the 0.5Ω resistor as shown).
Select the DMM DC volts function.
