You can use scans to perform a user-specified sequence of close and open operations on multiple
channels. Refer to
Close and open channel operations and commands
When you turn on the Model 707B or 708B, relays for all switch cards in the instrument are opened.
When you close channels, you have the option to do an exclusive close for the channel or slot. An
exclusive channel close closes the selected channel and opens any other channels that are closed.

channels that are closed on the same slot as the selected channel. With an exclusive slot close, any
channels that are closed on other slots remain closed.
