环境试验箱仪器设备仍是一种精密、贵重设备。正确使用和操作环境试验设备不仅能为检测人员提供准确的依据,而且能使环境试验设备长时间的正常运行和延长其设备的使用寿命。

        首先在做环境可靠性试验时,对所需试验的样品性能、试验条件、试验程序和试验技术要熟悉,要对所使用的试验设备的技术性能要熟悉,对设备的构造要有所了解,尤其是对控制器的操作及性能要熟悉。还要仔细阅读试验设备的操作使用手册,这样可以避免因操作失误而引起试验设备的不正常运行从而引起试验样品的损坏,试验数据的不正确。

        其次,合理选择环境试验箱试验设备。为保证试验正常进行,应该根据试验样品的不同情况,选择合适的试验设备,试验样品和试验箱的有效容积之间也要保持一个合理的比例。

对于发热试验样品的试验,其体积应不大于试验箱有效容积的十分之一。对于不发热试验样品其体积应不大于试验箱有效容积的五分之一。比如,一台21`彩电在做温度储存试验时,选用一个一立方体积的环境试验箱就能满足要求,而在通电工作时,它就不能满足要求了,应该换一个更大一些的试验箱,因为电视机在工作时要发散热量。

        第三,正确放置试验样品。试验样品的安放位置,应离开箱壁10cm 以上,对多个样品应尽量放在同一平面上。样品放置应不堵塞出风口和回风口,给温湿度传感器也应留出一定距离。以保证试验温度的正确。

The
chamber equipment is a sophisticated, expensive equipment. The proper use and operation of environmental testing equipment () can not only provide an accurate basis for the testing personnel, and make environmental testing equipment uptime and extend the life of their equipment.
        First
tests on the sample performance of the required tests, test conditions, test procedures and test techniques to be familiar with, to be familiar with the technical performance of the test equipment used to understand the structure of the device. In particular, be familiar with the operation and performance of the controller. Also carefully read the operating manual of the test equipment, to avoid causing damage to the test sample due to operational errors caused by the normal operation of test equipment, test data is not correct.
        Second, a reasonable choice of the environmental chamber (testTo ensure that the test is normal, should be based on the different circumstances of the test sample, select the appropriate test equipment, test samples and the effective volume of the chamber have to keep a reasonable proportion.
Heating test sample test, its size should not exceed one tenth of the effective chamber volume. Not heat the test sample volume should be not more than one fifth of the chamber effective volume. For example, a 21 'color TV in temperature storage test, the choice of a cubic volume the chamber www.jianhutest.com will be able to meet the requirements of work in the power, it can not meet the requirements, it should be a greater some of the chamber, because the TV at work to diverge heat.
        Third, the correct placement of the test sample. The placement of the test sample, should leave the walls of the box than 10cm, multiple samples should be placed in the same plane. Place the sample should not be clogging the outlet and return air temperature and humidity sensor should set aside a certain distance. To ensure that the correct test temperature.
