Logging will not start until the value rises above or falls below the set

Pre-trigger
If ‘sensor rises’ or ‘sensor falls’ has been selected as the trigger event
and the selected logging duration/interval is fast enough, an option to
set a pre-trigger will be available [None, 25%, 50%, 75%, and 100%].
Pre-trigger will cause a percentage of samples to be taken before the trigger condition is met and
the remainder to be taken afterwards e.g. if 1,000 readings are to be taken and a 25% pre-trigger
is selected, 249 readings will be taken before the trigger condition is met.
If pre-trigger readings are not required leave the selection as None.
Scroll
through the choices and press the green button to select.

Recording will start as soon as the trigger condition is reached. The bottom line of the LCD .
