When you reset the relays in a slot:
•
Any closed channels open
•
Labels return to default of slot, row, column
•
Delays are set to zero
•
If the channel is forbidden to close, it is cleared from being forbidden to close
•
If any of the slot’s channels are in channel patterns, the patterns are deleted

Scan Builder page
The Scan Builder page allows you to set up and run scans and triggers.
A scan is a series of steps that opens and closes switches sequentially for a selected group of
channels. During each step, actions occur, such as waiting for a trigger, taking a measurement on an
external instrument, and completing a step count. Scans automate actions that you want to perform
consistently and repeatedly on a set of channels.
Triggers are events that prompt the instrument to move from one step to another in a scan. Triggers
can come from a variety of sources, such as a key press, digital input, or expiration of a timer. The
sequence of actions and events that occur during the scan is called the trigger model, described in
(on page 3-1).
Scanning and triggering allow you to synchronize actions across channels. You can set up a scan
using the trigger model to precisely time and synchronize the Model 707B or 708B between channels
and multiple instruments. You can also use triggers without the triggering model to set up a scan to
meet the needs of a specific application that does not fit the triggering model.
If you use Scan Builder to create a scan, use the options in the Scan Builder page to run the scan.
Using the TSB Embedded page may not give you the expected results.
