The displays do not have a Real Time Operating System (RTOS). Because of this the display should not
be used as the master control for any type of safety critical control, or closed loop control system.
Frequency inputs are managed by the operating system. Because of this it should be avoided to use
these inputs for any type of Safety Critical closed loop control as the accuracy maybe affected by
processor load. They should only be used for non-safety critical related functions.
