Introduction to constant temperature and humidity test cases of the operation of the matters needing attention

Constant temperature and humidity test chamber can be used to assess and clear electric electronic product or material storage and use in the temperature and humidity environment adaptability. Equipment selection of forced air circulation, keep indoor temperature and humidity even work. In the process of test, test samples will not be direct source of heating and cooling equipment components. Following a brief introduction for the convenience of customers to use, the points for attention during the operating equipment. To open the doors of constant temperature and humidity test chamber, put the sample in test chamber sample rack, and ensure the sample and there are certain spacing among the walls, surrounding the sample indoor and ventilated. Check the test chamber lower water tank water level is more than 3/5. If less than 3/5, when drawn the level above the humidifying water tank water. In the process of test, should often check the water level in the tank, to ensure that the trial period has adequate power supply. Constant temperature and humidity test chamber is not explosion-proof type, please do not use in inflammable and explosive gas environment. When operating, please don't open the constant temperature and humidity test chamber door as much as possible. High temperature open is likely to lead to the operator burns, low temperature open is likely to lead to the operator cause frostbite, and is likely to lead to the evaporator frozen, refrigeration effect. If must be open, please do a good job in maintenance. Prohibited to tear open outfit, the production processing, upgrading or servicing of constant temperature and humidity chamber, otherwise an error operation, the risk of electric shock or fire accident. Vents should maintain a constant temperature and humidity test chamber shell smoothly and avoid the abnormal action, reduce the service life of the common faults, and the fire accident. Constant temperature and humidity test chamber split open a case, if the equipment damage or deformation, do not use. In the process of equipment installation and the installation, pay attention to don't let the dust, external thread, iron pin or other items into the, or it will produce error operation or common faults. Laboratory wiring must be appropriate, be sure to grounding device. No grounding device is likely to result in electric shock accidents, errors, operation safety accidents, large display abnormal information or data error. Regular maintenance terminal screws and fixed bracket. Please do not use when they loose them. Instruments and equipment in constant temperature and humidity test chamber work, be sure to install type switch power supply terminals in the terminal board cover, avoid electric shock accidents. Instrument in the process of operation, the changes in the setting, data signal output and start-stop operation process, should take into account the factor of safety, the error will be destroyed or make work equipment is invalid. Please use wet cloth to scrub constant temperature and humidity chamber, without having to use ethanol, motor gasoline, or other solvents, don't sprinkling water on the equipment, if the equipment into the water, please stop immediately, otherwise there are leaks, the risk of electric shock or fire. Equipment internal parts in the constant temperature and humidity test chamber has a certain use. In order to keep the safety use of instruments and equipment, to carry out maintenance on time, please. The interpretation of the above is the constant temperature and humidity test chamber operation considerations, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
