The use of constant temperature and humidity chamber precautions

The constant temperature and humidity test chamber has a completely independent system of high temperature and low temperature. It is used to test the heat resistance, cold resistance, dryness and moisture resistance of the equipment in various environments. Widely used in electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical care, aerospace and other fields.

Operating temperature and humidity box should pay attention to:

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

2. To prevent electric shock or malfunction and failure, do not turn on the power until the installation and wiring are completed.

3, this product is non-explosion-proof products, please do not use constant temperature and humidity in the environment of flammable or explosive gas.

4. Please don't open the test box door when the instrument is working. Open it at high temperature may cause scalding to the operator. Opening it at low temperature may cause frostbite to the staff in the early morning and may cause the evaporator to freeze and affect the cooling effect. If you have to open it, please do some protective work.

5. It is forbidden to dismantle, process, reform or repair the constant temperature and humidity machine without authorization, otherwise there will be danger of abnormal operation, electric shock or fire.

6. Ventilation holes of the airframe should be kept unobstructed to avoid malfunctions, abnormal movements, reduced life expectancy and fire.

7. If the machine is damaged or deformed when it is unpacked, please do not use it.

8. When installing the machine, be careful not to allow dust, thread, iron chips or other things to enter. Otherwise, wrong actions or malfunctions may occur.

9, the wiring must be correct, must be grounded. Ungrounded may cause electric shock, malfunction, abnormal display, or large measurement error.

10. Regularly check the terminal screws and holders. Do not use them loosely.

11. During the operation of the instrument, the power input terminal cover must be installed on the terminal board to prevent electric shock.

12. Before the instrument is in operation, before modifying the settings, signal output, starting, stopping, etc., the safety should be fully considered. The wrong operation will cause the working equipment to be damaged or malfunction.

13. Use a dry cloth to wipe the meter. Do not use alcohol, gasoline, or other organic solvents. Do not spill water on the meter. If the meter is immersed in water, stop using it immediately. Otherwise, there is a risk of leakage, electric shock, or fire.

14. The internal parts of the instrument have a certain life span. To use the instrument continuously and safely, please perform regular maintenance and maintenance. When disposing of this product, dispose of it according to industrial waste.
