RReegguullaarr CChheecckk
A comprehensive check must take precedence if it coincides with a regular check.
A regular check is intended only to demonstrate the STO is functional. It will not always detect the loss of a single
channel. It is therefore important for the user and / or machinery builder to determine the frequency of the
comprehensive checks based on their knowledge and application of the machine.
