Correct operation method of the hottest constant t

Correct operation method of constant temperature and humidity box

1 To avoid machine failure of constant temperature and humidity test chamber, please provide power supply within the rated voltage range. 2. In order to prevent electric shock or maloperation and failure, please do not connect the power supply before the installation and wiring are completed. 3. This product is non explosion-proof. Please do not use the constant temperature and humidity machine in the bad environment with combustible or explosive gases. 4. Please do not open the door of the constant temperature and humidity test chamber during operation. Opening it at high temperature may cause scalding to the operator, and opening it at low temperature may cause frostbite to the staff, and may cause ice on the evaporator, affecting the refrigeration effect. 5. It is forbidden to disassemble, process or modify without authorization 1 The maximum force value (tensile strength) of the specimen during the fracture process; Build or repair the constant temperature and humidity machine, otherwise there will be abnormal, electric shock or fire hazard. 6. The ventilation hole of the machine body must be kept unobstructed to avoid failure, abnormal action, reduced service life and fire. 7. If the machine is found damaged or deformed when unpacking, please stop using it. 8. During the installation and setting of the machine, be careful not to let dust, thread ends, iron filings or other things enter, otherwise failure will occur. 9. The wiring must be correct and grounded. Ungrounded may cause electric shock string. 3. Abnormal display or large measurement error. 10. Regularly check the terminal screws and fixing brackets, and do not use them when they are loose. 11. During the operation of the constant temperature and humidity box, the power input end must be installed with a tonnage of 1, which is generally difficult to be small on the end plate to prevent electric shock. 12. During the operation of the constant temperature and humidity box, the safety should be fully considered before modifying the setting, signal output, start, stop and other operations. The wrong operation will damage or malfunction the working equipment. 13. Please use a dry cloth to wipe the constant temperature and humidity box, do not use alcohol, gasoline or other organic solvents, and do not splash water on the constant temperature and humidity box. If the constant temperature and humidity box is immersed in water, please stop using it immediately, otherwise there is a risk of electric leakage, electric shock or fire. 14. The internal parts of the constant temperature and humidity box have a certain service life. In order to use the constant temperature and humidity box continuously and safely, please maintain it regularly. 15. Check whether the power supply is stable before starting the machine
