The system works (fan, cooling, dehumidification, heating, humidification) by touch screen man-machine The interface is centrally controlled. The whole assembly is carried out on the customer side, the transportation is convenient to arrange, and on-site commissioning and acceptance are carried out on the customer side to ensure the performance of the use on the customer side; The degree of structural integration is high, the assembly and debugging time is short in the client; the scientific air circulation design makes the indoor temperature and humidity uniform, avoiding any dead angles; the complete safety protection device avoids any potential safety hazards and ensures long-term reliability of the equipment. Sex; each product is customized according to customer requirements, ensuring efficient and energy-saving equipment. In order to avoid mechanical failure in the constant temperature and humidity test chamber, please pay attention to the following items: 1. To avoid machine failure in the constant temperature and humidity test chamber, please provide power supply within the rated voltage range. 2. In order to prevent electric shock or malfunction and malfunction, do not turn on the power before installation and wiring are completed. 3. This product is a non-explosion-proof product. Please do not use a constant temperature and humidity machine in the environment with flammable or explosive gas. 4. Please try not to open the test box door during the operation of the instrument. If it is opened at high temperature, it may cause burns to the operator. Opening at low temperature may cause frost damage to the staff in the morning, and may cause the evaporator to freeze and affect the cooling effect. If you must open it, please do some protection work. 5. It is forbidden to disassemble, process, modify or repair the constant temperature and humidity machine without authorization, otherwise there will be danger of abnormal action, electric shock or fire. 6. The ventilation holes of the body should be kept open to avoid malfunction, abnormal operation, reduced life and fire. 7. Do not use the machine if it is found to be damaged or deformed when unpacking. 8. Be careful not to let dust, thread, iron filings or other things enter during machine installation, otherwise malfunction or malfunction will occur. 9. Wiring must be correct and must be grounded. Failure to ground may result in electric shock, malfunction, abnormal display, or large errors in measurement. 10. Check the terminal screws and holder regularly, please do not use them loosely. 11. During the operation of the instrument, the power input terminal cover must be installed on the terminal block to prevent electric shock. 12. Before the instrument is in operation, the safety should be fully considered before the operation of modifying the setting, signal output, starting, stopping, etc., and the wrong operation may cause the working equipment to be damaged or malfunction. 13. Please wipe the meter with a dry cloth. Do not use alcohol, gasoline or other organic solvents. Do not splash water on the meter. If the meter is immersed in water, stop using it immediately, otherwise there is danger of electric leakage, electric shock or fire. 14. The internal parts of the instrument have a certain life span. For the continuous and safe use of the instrument, please carry out regular maintenance and maintenance. When disposing of this product, please dispose of it according to industrial waste. Then how does the constant temperature and humidity test chamber be maintained, cleaned and maintained in daily work? 1. Cleaning and maintenance of the inside and outside of the constant temperature and humidity test chamber (1) The constant temperature and humidity test chamber should be cleaned of internal impurities before operation. (2) The power distribution room should be cleaned at least once a year. Above, you can use a vacuum cleaner to remove indoor dust during cleaning. (3) The outside of the cabinet must be cleaned more than once a year. When cleaning, first wipe it with soapy water. 2. Check and maintenance of constant temperature and humidity test chamber humidifier The water storage in the humidifier should be replaced once a month to ensure the water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow. 3. Constant temperature and humidity test chamber Check the over-temperature protection device. When the constant temperature and humidity test chamber is running, the over-temperature protection setting is set to a high value of 20 ° C ~ 30 ° C. When the temperature in the test box rises to the set point of over-temperature protection, the power supply of the heater will stop. The "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is running for a long time and unattended, please check it before running. Over temperature protector, is set properly [the wet bulb over-temperature protector is set to 120 ° C]. 4. Constant temperature and humidity test chamber Condenser dust removal The condenser should be regularly maintained monthly, using a vacuum cleaner to remove the dust attached to the condenser heat sink or use high pressure air to spray dust. 5. Constant temperature and humidity test chamber Wet ball test cloth replacement When the test cloth surface is not clean or hardened, or after the temperature control is completed, the test cloth must be replaced before continuing to do the temperature and humidity sphericity control. The test cloth should be replaced once every three months. When replacing the cloth, wipe the temperature measuring body with a cleaning cloth. When replacing the new test cloth, it should be cleaned first. 6. Check and adjust the water level of the wet bulb in the constant temperature and humidity test chamber. The water level of the water tank should not be too high, so that the water overflows the water tank or the water level is too low, so that the wet bulb test cloth absorbs water abnormally, affecting the accuracy of the wet bulb. You can fill it up. The water level of the water tank can be adjusted to adjust the level of the water tank. 7. The constant temperature and humidity test chamber will not be used for a long time, and the equipment should be energized regularly every month. The power-on time is not less than 1 hour.
