| During the illumination, the temperature in the chamber should rise to the setting temperature control value with an almost linear speed and keep it stable (the typical setting value is + 55 ℃ and 40 ℃). During no illumination, the temperature in the chamber should drop to the setting temperature control value with an almost linear speed and keep it stable (the typical setting value is +25℃). Under different test procedures, the relations between the temperature, irradiation and time during testing are shown in Chart 2. | ||||||||||
