The problem of the inability of the high and low temperature impact test chamber to heat up may be caused by various factors. The following are some common reasons and corresponding solutions:

Temperature probe malfunction:

Possible reason: The temperature probe is damaged or malfunctioning, which makes it impossible to accurately detect the temperature inside the box, thereby affecting the heating process.

Solution: Check if the temperature probe is intact. If it is damaged, replace it with a new one.

Aging or damage of heating tube:

Possible reason: The heating tube may experience aging or damage after prolonged use, resulting in a decrease in heating efficiency and inability to reach the expected temperature.

Solution: Check the condition of the heating tube. If it is aging or damaged, replace it with a new one.

Temperature acquisition system delay:

Possible reason: The delay time of the temperature acquisition system is too long, causing the system to be unable to respond to the temperature rise command in a timely manner.

Solution: Optimize the settings of the temperature acquisition system, reduce delay time, and improve response speed.
