In the last article, we talked about the problem that the temperature of the test chamber and saturation tank of the salt spray test chamber could not rise to the set temperature and gave answers. Below we continue to discuss other common problems and treatment methods of the salt spray test chamber.

5. Cannot run after turning on the power

Cause of failure: When the water level in the heating tank is too low, the power supply for operation will be cut off.

Treatment method: increase the water level of the heating tank to normal conditions.

6. When the temperature controller displays HHH, LLL

Causes of failure: temperature controller failure, temperature sensor failure.

Solution: Notify the maintenance company for home repair.
