Details
This setting controls the aperture of measurements made for contact check. It does not affect the
smu
X
.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
Configure contact check for higher accuracy
on SMU channel A.

.contact.threshold =
rValue
rValue
The resistance above which contact check should fail (measured in ohms)
X
Source-measure unit (SMU) channel (for example,
smua.contact.threshold
applies to SMU channel A)
Details
The threshold should be set to less than 1 k
Ω
.
Example
smua.contact.threshold = 5
Set the contact check threshold for SMU channel A to 5
Ω
.
