Details of Trigger States

These paragraphs use flow charts to explain the decision making rules

inside each trigger state. These rules govern how the instrument

moves between adjacent states. Some of the flow charts reference

commands that have not been discussed yet. These commands

are explained later in this subsection. Keep in mind that this

explanation covers the most general case. Your particular instrument

may not implement all of the commands discussed here.
