The two box cold and hot shock testing machine does indeed have a power-off program memory function, which can automatically start and continue to execute the program after power is restored. Here are specific instructions:

1. Power off program memory function: This function is implemented through a built-in controller, which uses high-precision LCD touch buttons or large LCD displays, with data storage and program memory capabilities. During the operation of the device, if a sudden power outage occurs, the controller will automatically record the program status before the power outage, including key parameters such as the currently executed program segment, remaining time, and number of cycles.

2. Automatic restart and program connection: When the power is restored, the testing machine can automatically start and continue to perform unfinished tests based on the program status recorded before the power outage. This process does not require manual intervention, ensuring the continuity and accuracy of the testing. For example, if the testing process is interrupted due to a power outage, the equipment will automatically return to the temperature setting and impact conditions before the power outage after power restoration, and continue to complete the remaining testing cycle.

Technical Implementation and Advantages of Two Box Cold and Hot Shock Testing Machine:

1. Controller performance: Adopting an imported controller with high-precision PID parameter self-tuning function, it can automatically adjust control parameters according to testing requirements, ensuring the stability and accuracy of temperature control.

2. Data storage capacity: Some models have high program memory capacity and can store multiple sets of programs to meet complex testing needs.

3. Convenient operation: By programming the control program through human-machine dialogue, the refrigeration machine can automatically operate by simply setting the temperature. At the same time, it has real-time display of graphical curves, making it convenient for users to monitor the testing process.

Application scenarios and value of two box type cold and hot shock testing machine:

1. Aerospace: Simulate the temperature shock resistance of spacecraft electronic components in the space environment to ensure the reliability of equipment under extreme temperature changes.

2. Electronic appliances: Test the material expansion/contraction and solder joint reliability of products such as mobile phones and circuit boards under rapid temperature changes to improve product quality.

3. Automotive manufacturing: Verify the sealing and thermal management performance of the engine compartment and battery pack under extreme temperature cycling to ensure driving safety.
