Vehicle mapping examines how temperature is distributed through the body for a defined load and operating pattern. The unit display, body air and product measurement are different variables; the plan should name them separately.
Prepare a mapping sketch first
Mark the interior dimensions, air supply and return, doors, load layout and sensors. Record a coordinate or description for each point, logger ID, calibration information and sensor type. Do not assume one fixed sensor count or risk location applies to every vehicle.
Use an empty run to assess air distribution and a loaded run to assess conditions around the product. Link representative load, vehicle configuration, starting condition, route, door openings and unit settings to the record. Cover seasonal conditions in a separate run or approved plan.
If product measurement is needed, identify its method and point separately from an air sensor. Record the load's starting condition and packaging; do not assume a body sensor measures product core.
The report should include the sketch, raw data, test conditions, deviation review and proposed permanent monitoring points. Review the scope if load layout, route or vehicle changes.
A specific sensor grid or repeat interval is not universal. The organisation's quality system and applicable product or transport requirements should determine mapping scope.
