Precautions for the operation of the constant temperature and humidity test chamber - high-altitude test

Constant temperature and humidity test chamber can be used to assess and determine the adaptability of electrical and electronic products or materials in the temperature and humidity of environmental conditions storage and use, with a number of protection systems, in the operation of the equipment, there will be operating instructions, when the failure occurs, the constant temperature and humidity test chamber will take sound and light alarm and other protection. So what are the operating precautions for the constant temperature and humidity test chamber? The following is the introduction of Gao Tianxiao.

1. In order to avoid machine failure in the constant temperature and humidity test chamber, please provide the power supply within the rated voltage range.

2. If the machine is found to be damaged or deformed when unpacking, please do not use it.

3. In order to prevent electric shock or malfunction and failure, please do not turn on the power before the installation and wiring end.

4. This product is a non-explosion-proof product, please do not use a constant temperature and humidity machine in a combustible or explosive gas environment.

5. It is forbidden to disassemble, process, transform or repair the constant temperature and humidity test chamber without authorization, otherwise there will be a risk of abnormal action, electric shock or fire.

6. The ventilation holes of the body of the constant temperature and humidity test chamber should be kept unobstructed to avoid failure, abnormal action, reduced life and fire.

7. When the machine is installed and set up, be careful not to let dust, wire, iron filings or other things enter, otherwise there will be wrong actions or failures.

8, constant temperature and humidity test chamber work, please try not to open the test box door, open at high temperature may cause burns to the operator, open at low temperature may cause frostbite to the staff in the morning, and may cause the evaporator to freeze, affecting the refrigeration effect. If you must open it, please do a certain amount of protection.

9, the laboratory wiring must be correct, must be grounded. Failure to ground may result in electric shock, mismanagement, display abnormalities, or large measurement errors.

10. During the operation of the constant temperature and humidity test chamber instrument, the power supply inlet terminal cover must be installed on the terminal board to prevent electric shock.

11, the instrument in operation, before modifying the settings, signal output, start, stop and other operations, should fully consider the safety, the wrong operation will make the work equipment damage or failure.

12, please use a dry cloth to wipe the instrument, do not use alcohol, gasoline or other organic solvents, do not splash water on the instrument, if the instrument is immersed in water, please stop using it immediately, otherwise there is a risk of leakage, electric shock or fire.

13. Check the terminal screws and retention mechanism regularly, please do not use them in the case of looseness.

14, constant temperature and humidity test chamber instrument internal parts have a certain life cycle, in order to continue to use the instrument safely, please regularly maintain and maintain.

15, constant temperature and humidity test box in the handling, should be careful to avoid damage to the panel on the instrument and other vulnerable parts, refrigeration function of the product handling inclination angle should not be greater than 45 ° C, placed in place, should be placed for 1 to 2 days and then start, is conducive to the refrigeration system can work normally and prolong life.

The above on the operation of the constant temperature and humidity test chamber precautions for everyone to share here, constant temperature and humidity test chamber is aviation, automotive, home appliances, scientific research and other fields of the necessary test equipment, for testing and determining the electrical, electronic and other products and materials for high temperature, low temperature, alternating wet heat or constant test of the temperature environment after the change of parameters and performance.
