11    Automatic Startup and Stop (Standby) of                                                                             14    Rapid and Precise Sample Setting
                  Device is Possible

            The X-ray unit can be automatically started up by registering                                                             The swing arm system sets a sample precisely within 5 seconds,
            the device startup date and time in advance.                                                                              in a single motion. This simple design minimizes down time and
            Automatic stop (standby) can be set in the same way.                                                                      ensures stable performance even in high-duty operation.
