Details
There is only one password per card. Therefore, channel.calibration.password() 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 instrument. The password is not permanently saved until the
channel.calibration.save() command is sent. Passwords are alphanumeric and case-
sensitive.
This command generates an error if calibration is locked or if the password string length is greater
than six characters.
The default password from the factory is KI3706.
Example
channel.calibration.unlock("slot3","KI3706")
channel.calibration.password("Unlock")
channel.calibration.save()
channel.calibration.lock()
Unlock the calibration for the card in slot 3,
assuming the default password is still valid.
Set the password to "Unlock" for the card in
slot 3.
Save the password for the card in slot 3 for
subsequent unlocks.
Lock the calibration for the card in slot 3.

Usage
channel.calibration.save()
Details
Only one card can be calibrated at a time. Therefore, channel.calibration.save() works only
on the presently unlocked card. An error is generated if this command is issued when calibration is
already locked.
The system must receive this command before the channel.calibration.lock() command or
the calibration data will be lost.
This command saves the present values of the calibration constants and calibration date, and
increases the calibration count by one, regardless of errors in the data. You should not issue
channel.calibration.save() unless the calibration procedure was performed with no errors.
If no calibration date was specified using either channel.calibration.adjustdate() or
channel.calibration.verifydate(), the date is automatically assigned based on the system
date.
