I don't know of an operating instruction "specifically" for the camera itself or a deeper Anafi lesson, but if you google "ASTM ROOFING C1153" you should be able to find the actual industry standard practice instructions which pertain to IR Roof Inspections.
Terminology, Techniques, Instrument Requirements, Required Conditions, etc. are covered. A must have if you are doing inspections. You will need to have this as reference in case there are any discrepancies with a customer.
There are also standard instructions for electrical and building inspections.
