In preparation for taking illumination measurements, operate the vehicle engine by idling or driving the test vehicle, with the vehicle's HVAC system turned off, for a minimum of 20 minutes, after which the engine is turned off. Illumination measurements are then recorded no later than 10 minutes after the time the engine is turned off, with the vehicle in a location where there is no apparent ambient light, and with the sensing element of the measuring device within 50 mm (2 inches) of the platform surface being measured.
