Trigger conditions are expressions evaluated by the Signal Signal reader module to control when recorders are started and stopped and when measurement set-up switches are performed. Trigger conditions are boolean expressions, evaluated to either true or false. A number of operators can be combined to for the trigger expression. The allowed operators in trigger expressions are shown in the table below.
