channel.calibration.lock()
This function prevents further calibration on the currently unlocked card.
Type TSP-Link accessible
Affected by Where saved Default value
Function Yes
Usage
channel.calibration.lock()
Details
Calibration data is locked during normal operation. To perform calibration, calibration must be
unlocked (
channel.calibration.unlock()
) for the card.
Only one card can be calibrated at a time. Therefore,
channel.calibration.lock()
works only
on the currently unlocked card. Once locked, you must unlock calibration to perform it again.
This command locks calibration on the card being calibrated, but does not save calibration data.
Calibration data is lost if it is not saved before locking. Refer to
channel.calibration.save()
for more information.
An error is generated if this command is issued when calibration is already locked.
Example
channel.calibration.unlock("slot1","KI3706")
-- Perform operations to generate the calibration data
channel.calibration.save()
channel.calibration.lock()
Unlock the card calibration for slot 1 using the default password.
Use the
channel.calibration.step
command to generate the calibration data.
Save the calibration data for the card in slot 1, if no errors occurred while generating the calibration data.
Lock the calibration data for the card in slot 1.
