Trigger
Actuating the trigger freezes an image prior to storage. While in a regular measurement
mode, pull the trigger momentarily, release it, and the thermal image on the display will be
frozen so you can evaluate it for storage. If you don’t want to store it, simply pull the trigger
again and the unit will go back to measurement mode.
