Section 16: Calibration Series 2600 System SourceMeter® Instruments Reference Manual
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)
4. 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
2611/2612/2635/2636).
5. Change connections as shown in Figure 16-3 (use 4-wire connections to the 0.5Ω resistor
as shown).
6. Select the DMM DC volts function.
7. Repeat steps a through v for the 3A and 10A ranges (Model 2601/2602) or 1.5A and 10A
ranges (Model 2611/2612/2635/2636). Compute the current reading from the DMM voltage
reading and characterized 0.5Ω resistance value: I = V/R.
8. Select auto polarity mode:
smua.cal.polarity = smua.CAL_AUTO
