Smux.contact.threshold - Keithley 2601B Reference Manual

Section 7: TSP command reference
Details
This setting controls the aperture of measurements made for contact check. It does not affect the
smuX.measure.nplc aperture setting.
The speed setting can have a dramatic effect on the accuracy of the measurement (see specifications).
Example
smua.contact.speed = smua.CONTACT_SLOW

smuX.contact.threshold

This attribute stores the resistance threshold for the smuX.contact.check() function. This attribute is not
available on the Models 2604B/2614B/2634B.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
rValue = smuX.contact.threshold
smuX.contact.threshold = rValue
rValue
X
Details
The threshold should be set to less than 1 kΩ.
Example
smua.contact.threshold = 5
