What type of test should be performed prior to running the program in continuous mode?

The step test is critical prior to running a program in continuous mode because it allows the operator to verify each individual command and motion of the robot in a controlled manner. By executing the program step-by-step, any potential issues or errors can be detected early, ensuring that components function as intended and that there are no surprises when the program is run continuously.

This approach enhances safety and reliability, as it minimizes risks such as mechanical failures or improper sequence execution, which could lead to accidents or damage to equipment. Step testing is integral for confirming that all movements, orientations, and tool operations are precise before the program is allowed to operate autonomously without further human intervention.

In contrast, the other types of testing mentioned do not specifically address the need to verify the execution of each program instruction sequentially. A pressure test typically assesses the integrity of systems under pressure, a flow test evaluates the efficiency of fluid movement, and an integrity test checks for overall stability and correctness of the system but does not provide the same level of detail in amendments and verification as step testing does.
