Compensate for trigger
I believe the answer is:
set off
I believe this clue is a double definition.
'compensate' is the first definition.
(thesaurus)
'trigger' is the second definition.
('set off' can be a synonym of 'trigger')
'for' is the link.
(Other definitions for set off that I've seen before include "'Leave on a journey (3,3)'" , "Begin journey or explode bomb" , "Depart" , "Begin journey or cause to ignite" , "contrast" .)
