Q&A:
Q1: How to operate the programmable constant temperature and humidity test chamber?
A1: Operating a programmable constant temperature and humidity test chamber usually includes the following steps:

Open the main switch.
According to the experimental needs, check and adjust the water level of the water tank (if it is a humidity experiment), or take out the wet ball gauze (if it is only a high temperature experiment).
When placing the sample, pay attention to maintaining a certain distance between the sample and the box to prevent the sample from being too dense and affecting the air flow.
Turn on the power switch on the instrument panel.
Adjust or set the required temperature and humidity parameters through the touch screen.
During the experiment, do not open the door unless necessary. If you need to observe, you can use lights.
After the experiment is completed, turn off the power of the instrument and the main switch, and ensure that the temperature has cooled to a safe range before opening the door to take out the sample.
Q2: How to maintain the programmable constant temperature and humidity test chamber?
A2: The maintenance of programmable constant temperature and humidity test chamber includes:

The storage environment should be maintained between 5 and 35 degrees, with good ventilation and humidity below 85%.
Check the wet bulb water level regularly to ensure the accuracy of the water level remains within a certain range.
Regularly check and clean the humidification system, including pipes, humidification barrels, water cups and water tanks, using pure or filtered tap water.
The terminal blocks of electrical components should be tightened regularly and by persons with common knowledge as electricians.
Regularly clean the inside and outside of the test box, including the water bottle, the box, the power distribution room and the outside of the box.
Regularly check the refrigeration system pipelines to ensure that the valves are normal and leak-free.
Q3: What are the common faults of programmable constant temperature and humidity test chamber and how to solve them?
A3: Common faults and solutions include:

Panel over-temperature alarm: The compressor may be overloaded due to unstable voltage and current. It is recommended to shut down the machine and wait for the voltage to stabilize before turning it on again.
Heating tube heating alarm: This may require professional after-sales engineers to judge and solve.
Compressor overload alarm: usually occurs when there is water shortage. Check whether the water adding parts are leaking and repair or replace them in time.
