Contact check programming example
The command sequence for a typical contact measurements is shown below. These commands
set the contact check speed to fast and the threshold to 10Ω. A contact check measurement
against the threshold is then made. If it fails, a more accurate contact check measurement is
made, and the test is aborted. Otherwise, the output is turned on, and the test continues.

Set threshold to 10Ω.
if (not smua.contact.check()) then
--One/both contact resistances are not
