Function Yes
Usage
smuX.cal.restore()
smuX.cal.restore(calset)
X
Source-measure unit (SMU) channel (for example, smua.cal.restore() applies
to SMU channel A)
calset
The calibration set to be loaded. Set calset to one of the following values:
0 or smuX.CALSET_NOMINAL: A set of calibration constants that are uncalibrated,
but set to nominal values to allow rudimentary functioning of the instrument
1 or smuX.CALSET_FACTORY: The calibration constants when the instrument left
the factory
2 or smuX.CALSET_DEFAULT: The normal calibration set
3 or smuX.CALSET_PREVIOUS: The calibration set that was used before the last
default set was overwritten
Details
This function overwrites the present set of calibration constants with constants read from nonvolatile memory.
This function is disabled until a successful call to smuX.cal.unlock() is made.
If calset is not specified, smuX.CALSET_DEFAULT is used.
Example
smua.cal.restore()
Restores factory calibration constants for SMU channel A.
