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.

Usage
channel.calibration.step( channel , step )
channel.calibration.step( channel , step , value )
channel
The channel to be calibrated
step
The number corresponding to the specified step
value
The measured value for the specified step when the step value is even
Details
The specified channel must be on the unlocked slot. Only DAC and totalizer channels can be
calibrated. It is best to calibrate a single channel sequentially to completion before changing
channels.
The card assumes that the given voltage or current value is exactly what it is sourcing for the given
step. This command generates an error if the step is out of sequence, does not exist, or the
calibration is locked. Also, an error is generated if the calibration step does not complete successfully,
if the value passed is invalid or out of range for the step, or not needed.
For DAC channels, a calibration sequence includes these steps:
1. Set voltage,
–12 V to +12 V range, generate negative point 1.
2. Send reading.
3. Set voltage,
–12 V to +12 V range, generate negative point 2.
4. Send reading.
5. Set voltage,
–12 V to +12 V range, generate positive point 1.
