▪ 0 or smua.CONTACT_FAST
▪ 1 or smua.CONTACT_MEDIUM

Details
This setting controls the aperture of measurements made for contact check. It does not affect the
smua.measure.nplc aperture setting.
The speed setting can have a dramatic effect on the accuracy of the measurement (see
the specifications).
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.speed = smua.CONTACT_SLOW
Configure contact check for higher accuracy.
