smuX.cal.adjustdate = caldate
smuX.cal.date = caldate
smuX.cal.due = caldue
smuX.cal.lock()
smuX.cal.password = "newpassword"
smuX.cal.polarity = polarity
smuX.cal.restore([calset])
smuX.cal.save()
calstate = smuX.cal.state
smuX.cal.unlock("password")
smuX.measure.calibratei(range,
cp1measured, cp1reference,
cp2measured, cp2reference)
smuX.measure.calibratev(range,
cp1measured, cp1reference,
cp2measured, cp2reference)
Set calibration adjustment date for 2635A/2636A only.
Set calibration date (caldate of 0 indicated date not set).
Set calibration due date (caldue of 0 indicated date not set).
Lock out calibration.
Change password to "newpassword".
Set polarity:
smuX.CAL_AUTO
(auto polarity).
smuX.CAL_NEGATIVE
(negative polarity).
smuX.CAL_POSITIVE
(positive polarity).
Load calibration set of constants:
smuX.CALSET_NOMINAL
(nominal constants).
smuX.CALSET_FACTORY
(factory constants).
smuX.CALSET_DEFAULT
(normal constants).
smuX.CALSET_PREVIOUS
(previous constants).
Store constants in nonvolatile memory as DEFAULT
calibration set.
Request calibration state:
smuX.CALSTATE_CALIBRATING
smuX.CALSTATE_LOCKED
smuX.CALSTATE_UNLOCKED
Unlock calibration (default password: KI0026XX)
Calibrate current measure range:
2
±range (measurement range to calibrate).
cp1measured (Series 2600A measured value for cal. point 1).
cp1reference (reference measurement for cal. point 1).
cp2measured (Series 2600A measured value for cal. point 2).
cp2reference (reference measurement for cal. point 2).
Calibrate voltage measure range:
2
±range (measurement range to calibrate).
cp1measured (Series 2600A measured value for cal. point 1).
cp1reference (reference measurement for cal. point 1).

cp2reference (reference measurement for cal. point 2).
1.
smuX
= smua for the Model 2601A/2611A/2635A;
smuX
= smua (Channel A) or smub (Channel B) for the Model 2602A/2612A/
2636A.
2. Calibration point 1 should be performed at approximately 0% of range; calibration point 2 should be performed at approximately
90% of range. See Table 20-2 or Table 20-3 for calibration points.
