6.1 LOGIC TEST PROCEDURE
6.1 逻辑测试程序
DC voltage vi temperature
DC电压对温度
6.1.1Set the E.U.T. power supply output to the DC nominal Voltage EX: 5.0V.
6.1.1 设定待测物电压输出。例如: 5.0 V
传承雷锋精神6.1.2 Run the E.U.T. either with an on line or with an off line diagnostic test.
6.1.2 对待测物加电源，以便ON Line测试或OFF Line测试。
6.1.3 Set the temperature chamber to 25 ℃羊驼多少钱一只 and step the temperature up 10℃ every other hour until the system fails the diagnostic, the system stops functioning, or the chamber reaches a pre-terminal temperature.
(OPTIONAL T EMPERATURE RUN: Step the temperature chamber down in 10 ℃ C increments until the system fails the diagnostic, the system stops
functioning, or the chamber reaches a pre-terminal temperature.) Terminate this quence of temperature / Voltage adjustment and record the temperature and voltage readings.
6.1.3 设定恒温恒湿机到25℃，然后每次上升10℃ 达1 hr，直到产品损坏或至操作温度上限再停止电测，最后记录温度与电压的读值。
6.1.4 Ret the temperature to room ambient and verify that the unit under test is still functional.
6.1.4 温度重设至室温并确认样本在电测下无损坏。
6.1.5 If the system will not operate at this voltage level, to return the output voltage to nominal voltage to e if the system comes back to into operation.
6.1.5 如果系统不能操作在这个电压，则让输出回复至正常值再去看能否正常操作。
6.1.6 Return to Step 6.1 and proceed with the next voltage level.
6.1.6 以下一个电压测试时需重复步骤6.1。
7.0 TEST COMPLETION FUNCTIONAL TEST (完成试验后电测)：
如何正确戴口罩7.1 ANALOG TEST PROCEDURE (模拟的测试程序)：
(AC voltage vi temperature)
7.1.1Set the input voltage to the E.U.T. to the nominal AC Voltage EX: 115.0V. Subquent pass, to adjust the nominal input voltage to 90V and 132V. For Subquent pass, Adjust the nominal input voltage to 90V and 132V. For 220V systems adjust the nominal input voltage to 180V and 264V.
7.1.1 设定待测物的输入电压到正常AC电压
例如： 115V→可调整为90~132V
220V→可调整为180~264V。
7.1.2 Run the E.U.T. either with an on line or with an off line diagnostic test.
7.1.2 对待测物加上电源，以便ON Line西瓜的拼音或OFF Line测试。
7.1.3I Set the temperature chamber to 25 ℃ and step the temperature up
10 ℃ every other hour until the system fails the diagnostic, the system
stops functioning, or the chamber reaches a pre-terminal temperature.
(OPTIONAL T EMPERATURE RUN: Step the temperature chamber down in 10 ℃ increments until the system fails the diagnostic, the system stops functioning, or the chamber reaches a pre-terminal temperature.) Terminate this quence of temperature / Voltage adjustment and record the temperature and voltage readings.
