1. smuX = smua for the Model 2601/2611; smuX = smua (Channel A) or smub (Channel B) for the Model 2602/2612.
2. Calibration point 1 should be performed at approximately 0% of range; calibration point 2 should be performed at
approximately 90% of range. See

Set calibration date.
Set calibration due date.
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 non-volatile memory as DEFAULT
calibration set.
Request calibration state:
smuX.CALSTATE_CALIBRATING
smuX.CALSTATE_LOCKED
smuX.CALSTATE_UNLOCKED
Unlock calibration (Default password: KI002601, KI002602,
KI002611, or KI002612.)

Calibrate voltage measure range:
±range (measurement range to calibrate).
cp1measured (Series 2600 measured value for cal. point 1).
cp1reference (reference measurement for cal. point 1).
