smua.contact.threshold
This attribute stores the resistance threshold for the smua.contact.check() function.
Instrument reset
SMU reset
Recall setup
Usage
rValue = smua.contact.threshold
smua.contact.threshold = rValue
The resistance above which contact check should fail (measured in ohms)
Details
The threshold should be set to less than 1 kΩ.
Contact check is not available when the pulser is enabled. If you need to use the contact check
function in a pulser application, you can disable the pulser, run the contact check measurements,
then enable the pulser.
Example
smua.contact.threshold = 5
Set the contact check threshold to 5 Ω.

smua.interlock.enable
This attribute enables or disables use of the interlock signal.
Usage
interlockState = smua.interlock.enable
smua.interlock.enable = interlockState
Enable or disable use of the interlock signal:
â–ª Turn the output off if the interlock signal is not asserted: smua.ENABLE
â–ª Ignore the interlock signal: smua.DISABLE
