channel.calibration.lock()
Remarks
This command locks calibration on the card being calibrated, but does not save
calibration data (which is lost if it is not saved before locking). Once locked, you must
unlock calibration to perform it again.
Only one card can be calibrated at a time. Therefore, the lock function works only on
the currently unlocked card.
An error is generated if this command is issued when calibration is already locked.
Also see
channel.calibration.save() (on page 13-32)
Example
To lock calibration:
channel.calibration.lock()
channel.calibration.password()
Function
Sets the password needed to unlock the calibration of a card.
Usage
channel.calibration.password(<password>)
password: A string of characters that protects the command.
Remarks
There is only one password per card. Therefore, the password function works only
on the currently unlocked card.
Make note of the password, because there is no command to query for the password
once it has been set on the system.
This command generates an error if calibration is locked or if the password string
length is greater than six characters. Passwords are alphanumeric and case-sensitive.
The default password from the factory is KI3706. The first two characters in the
password are capital K capital I (for Keithley Instruments).
Also see
channel.calibration.unlock() (on page 13-34)
Example
To set the password to "MyUnlock" after unlocking calibration with the saved
password:
channel.calibration.password = "MyUnlock"
channel.calibration.save()
Function
Saves calibration data after performing a calibration.
Usage
channel.calibration.save()
