Diagnostic boundary
This tool does not measure refrigerant charge, determine equipment sizing, verify electrical or combustion safety, or replace professional diagnosis. Temperature readings depend on sensor location, airflow, runtime and instrument accuracy. If you see smoke, sparking, burning odor, severe vibration or water threatening electrical equipment, stop and seek qualified help.
