5 I-TECH D. Check Condition and Requirements: It is to check the thermal profile of the test unit,and also test unit can work under different environment temperature condition. The highest temperature /position, lowest temperature /position and the average temperature value will be display at the thermal profile record. The equipment in its high temperature mode, shall exposed to daily high-low temperature cycles between 30 C * 40 C and 55 C The equipment shall withstand the required environmental conditions and shall meet, without any functional damage, all performance requirements after being exposed to 1 cycles of high temperatures, as illustrated in Figurel. E. Test Result: Examine the appearance of specimen(s) by visual check and perform functional check after this test. Connect the specimen with rated power then examine whether the display function of specimen could be work normally or not. Functional Check & Mechanical Structure : Normal Appearance check(visual check) :No visible damage Temperature of Test Point: Temperature rise C of part: 30 C 40 C 55 C 1.
