1. When installing a constant temperature and humidity test chamber, its enclosure must be grounded; failure to do so may pose a risk of electric shock in the event of a leakage current. 2. Do not start the equipment hastily; ensure it is installed securely before operating it. 3. If the test samples in the studio are to be tested under electrical voltage, it is best to use an external power supply for connection, rather than drawing power directly from the test chamber. 4. Do not move the machine while it is in operation or when test samples are stored in the workroom, to prevent the samples from tipping over or falling. 5. After placing the machine, check whether the casters are secured; that is, adjust them so that they are in contact with the ground. Otherwise, the machine may move when subjected to external forces. 6. The installation of the constant temperature and humidity test chamber requires it to be in a horizontal position; otherwise, it may trigger alarms or result in unstable humidity control. 7. During operation, do not open the box door unless it is necessary for alignment; this could cause hot air to escape and result in burns to personnel. If opening the door is unavoidable, appropriate protective measures must be taken. 8. When connecting or disconnecting the communication interface cable between the test chamber and the computer, it is necessary to turn off the computer first; plugging in or unplugging it while it is powered on is not allowed, as this may damage the controller or the computer’s communication module. 9. Do not open the box door right after the test is completed; pay attention to the temperature inside the box to avoid burns or frostbite. 10. Flammable and explosive hazardous materials are prohibited from being placed in the constant temperature and humidity test chamber for testing.
