Smu.contact.threshold - Keithley 2461 Reference Manual

Model 2461 Interactive SourceMeter® Instrument Reference Manual

smu.contact.threshold

This attribute sets the threshold value for contact resistance for the contact check status functions.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
smu.contact.threshold = level
level = smu.contact.threshold
level
Details
The contact check functions indicate a failure when the connection path resistance exceeds the value
specified by this command.
This command can be sent when contact check isn't enabled. However, you must enable contact
check before checking the status of connections.
Example
smu.contact.threshold = smu.THRESHOLD_15_OHM
print(smu.contact.threshold)

Set the contact check function to indicate a
failure if resistance is greater than 15 Ω.
Query the contact check threshold setting.
Output:
