Contact check programming example
The command sequence for a typical contact measurement 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.
User setup
The Series 2600A can be restored to one of six setup configurations: Five user setups and one
factory default. As shipped from the factory, the Series 2600A powers-up to the original default
settings, which are also saved in the five user setup locations. Original default settings are listed in
the Instrument Command Library found in
Section 19. The instrument will power-up to whichever
default setup was saved as the power-on setup.
