What are the operations that cause the constant temperature and humidity chamber test results to be incorrect?

In fact, before using a constant temperature and humidity chamber, it's essential to provide proper training to the users. This step is crucial because improper operation can significantly affect the accuracy of test results. Below are some common mistakes that can lead to incorrect outcomes: 1. Ensure all samples are evenly distributed within the chamber’s effective testing area. Uneven placement can cause inconsistent temperature and humidity readings across different parts of the chamber. 2. Avoid opening the chamber door frequently during the test. Each time the door is opened, it disrupts the internal environment, which may lead to inaccurate or unreliable results. 3. When connecting or disconnecting the communication interface between the test chamber and the computer, always turn off the computer power first. Hot plugging can potentially damage the controller’s communication module or the computer itself, leading to system failures. 4. Never cut off the power supply while the equipment is operating at high temperatures, especially if there is a thermal load inside. Doing so can cause localized overheating, which might result in internal components being damaged or even burned out. It's also important to regularly check the chamber’s calibration and ensure that all sensors are functioning properly. Maintaining a clean and controlled environment inside the chamber is equally vital for accurate testing. Always follow the manufacturer's guidelines and keep detailed records of each test procedure. These practices not only help prevent errors but also extend the lifespan of the equipment.
