Contact check DUT connections
Contact check threshold resistances
There are three different threshold resistances available for contact check: 2,
15, and 50. (The factory default is 50.) These threshold values were chosen
to ensure that contact failures would be detected reliably. Table F-1 summarizes
recommended threshold values based on the resistance of the device-under-test.
