Correct operation of the temperature control system of a salt spray test chamber is extremely important because it ensures the accuracy of the test. Therefore, it is crucial to avoid any improper operations. So, what is the correct way to operate the temperature controller of the test chamber?
Here are some key points regarding the operation instructions for the temperature controller of a salt spray test chamber:
Adjusting the Temperature Setting: Use the up and down triangle keys to adjust the temperature value to the required level for the test. Generally, the controller will automatically determine the set value. If conducting a neutral salt spray test, the chamber temperature should be set to 35°C, and the bucket temperature should be set to 47°C. For an acidic test, the chamber temperature needs to be set to 50°C, and the bucket temperature should be set to 63°C.
Calibrating the Temperature Display: If you notice a discrepancy between the measured temperature and the displayed temperature, press the O key. The controller will then display “ATOFF.” At this point, press the C key to switch, and the controller will show “CN5.” Use the up and down triangle keys to adjust the temperature difference between the displayed temperature and the actual measured temperature.
Stabilizing the Temperature Display: If the displayed temperature shows fluctuations or instability, press the O key. The controller will display “ATOFF.” At this time, press the up triangle key, and “OFF” will change to “ON,” entering the automatic adjustment mode. Note that the power should not be turned off during this process. The equipment will stabilize the temperature in about ten minutes.
These methods can be used to adjust the temperature controller of a salt spray test chamber. The temperature controller of the device mainly relies on the temperature changes in the working environment of the test equipment. It undergoes physical deformation to produce special effects, forming a series of automatic control components, such as opening or closing actions. This is the temperature control switch and temperature protector. The configuration of these components is of great significance for the temperature adjustment of the test equipment. During the test, it is sometimes necessary to heat the salt solution to accelerate the corrosion of the test items. At this time, we need to use the temperature controller to adjust the pressure bucket temperature and the chamber temperature, so that the equipment can achieve accelerated corrosion and improve the test efficiency.
