Which panel(s) of the MJ-2A hydraulic test stand has most of the operating controls?

The main panel of the MJ-2A hydraulic test stand is designed to house the majority of the operating controls. It serves as the central point for operators, providing easy access to vital controls necessary for conducting hydraulic tests. The layout typically includes gauges, switches, and control levers that allow personnel to efficiently manage and monitor the hydraulic systems being tested. This central placement enhances usability and efficiency during operations, ensuring that the operator can focus on testing without needing to navigate multiple panels.

In contrast, while the front, side, and rear panels may contain some components, they do not provide the comprehensive array of controls found on the main panel, which is specifically designed for this purpose. Understanding the functionality of the main panel is essential for effectively operating the MJ-2A hydraulic test stand and ensuring accurate testing procedures.
