What is one of the functions of the mini test kit in the MK20 system?

The mini test kit in the MK20 system plays a crucial role in ensuring the safety and functionality of the diving equipment by serving the specific purpose of checking for leakage. This function is vital because any leakage in the system could lead to a significant risk for the diver, as it can compromise the supply of air and other necessary resources. By utilizing the mini test kit, divers and technicians can identify potential leaks before the dive, thereby maintaining operational integrity and enhancing safety measures.

This proactive approach to checking for leaks helps ensure that everything operates as intended during the dive, allowing for a more secure and effective underwater experience. Other options, while they might seem relevant, do not pertain specifically to the function of the mini test kit, reinforcing its specialized role in leakage detection as a critical safety measure.
