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.
smua.reset() --Restore defaults.
smua.contact.speed = smua.CONTACT_FAST --Set speed to fast.
smua.contact.threshold = 10 --Set threshold to 10Ω.
if (not smua.contact.check()) then
--One/both contact resistances are not
--below the programmed threshold.
smua.contact.speed = smua.CONTACT_SLOW
rhi, rlo = smua.contact.r()
print(rhi, rlo)
exit()
end

Check contacts against threshold.
Set speed to slow.
Get resistance readings.
Return contact resistances to the host.
Terminate execution.
smua.source.output = smua.OUTPUT_ON --Turn on output and continue.
