Sensor position, response and load produce different measurements; align measurement purpose and method before comparing.
First align measurement point, sensor position, load and times. A logger may measure air while a product probe measures another point and response; do not treat the difference alone as device failure or product condition. Refer assessment to the authorized process under product requirements.
Air and product readings may represent different points or responses.
Record proximity to plate, wall and door.
State air, surface or product point.
Next trip. Record method and times consistently.
Interpret the difference. Review position, response and load; do not infer automatically.
