Xi) Determination of trends and undesirable characteristics of main machinery under varying conditions. (xii) The acquisition of accurate operational data permits better performance analysis for current and future maintenance and provides a firm basis for studying future machinery design. A diagram of a typical data logging system is shown in Fig. 2. The sensing/transducing devices, which must provide an electrical output, are connected to a scanning system whose function is to switch each line in turn to a common channel for transmission to the next sub unit.

When red or green lenses or filters are used the difficulties are considerably less than with blue, orange or clear lenses. This is because most lamps emit yellow light which, for example, will mix with blue to give a greenish rendering. (b) Data Logging Even with all the above "information assimilating,, aids the watchkeeper's task of digesting all the information presented by a large number of instruments may be very great. Moreover, and what is often more important, human operators make mistakes.

V) To display the value of any selected variables in illuminated decimal digits. 38 CENTRALIZED AND AUTOMATIC CONTROLS IN SHIPS (vi) To provide a reduction in the number of conventional indicating and recording instruments. The advantages of data logging equipment may be summarized as: (vii) Early warning of potential breakdown. (viii) Factual records of performance. (ix) Watchkeeping staffis relieved of routine logging and recording duties. (x) Increased operating efficiency due to the close tolerance supervision of the machinery.
