Instrument Matrix - Continued

DOE-STD-1052-93

F6 -

instrument monitored on operator rounds

F7 -

provides computer input

NOTE:

Explanation of the types uses of the input

should be noted on the matrix.

F8 -

instrumentation that is used to continuously monitor

system, component, or plant performance or design

parameters (e.g., accumulator pressure indication)

F 9 - used for manual system operation

F10 - required for general indication

F11 - no required function

NOTE:

The functions of the instrument should be

clarified during an interview to ensure the

classification is correct.

Instruments that should be listed on the matrix are those

process devices that sense, switch, convert, indicate, and

transmit such parameters as flow, level, pressure, temperature,

The matrix should be distributed to appropriate operations,

technical support, and maintenance personnel. Each individual

should complete the matrix by placing an "X" in the designated

column if the instrument performs that function. Other

characters may be used to provide additional information on the

instrument's function. For example, it may be helpful to use a

"C", "S", or "P" to denote a component, system, or plant

function. An asterisk (*) may be used if the instrument is found

to provide a significant system function.
