Test Procedures
Fill the corrosion-resistant ceramic tank with water or saline solution to the required level.
Install wire samples on the support rack.
Set the test temperature using the digital PID controller.
Activate motor-driven stirrer to ensure uniform temperature distribution.
Connect DC voltage if required, and monitor current and voltage drop.
Start test and monitor automatically; system maintains water level and temperature.
After completion, stop the system, remove samples, and record test results.
