4.3.4Page Header.Two lines shall be centered at the top of each page: (First Line) HM&E MASTER INSTRUMENT LIST - (Vessel Class). The (Second Line) SORTED BY ________. Up to the first three columns used to sort the data base shall be listed on the SORTED BY line.

4.3.5Header Divider.A dashed line shall appear beneath the data item heading fields across the entire active area of the page.

4.3.6Field Spacing.No less than two character spaces shall be provided between each field allocated for each data item. The field allocation for each data item is defined herein.

4.3.7Page Numbering.Each data page shall be numbered at the bottom right-hand of the page beginning with page 1

4.4Data FieldsThe data fields shall be as follows:

4.4.1Reference number (REF #)The (REF #) for data entries shall range between 0001 and 9999. A sequential reference number shall be assigned to each instrument and control system component placed in the list. After assignment, the REF # identifies a unique instrument or control system component and is used only once. Grouping by systems or location is preferential. The REF # field shall not exceed six characters.

4.4.2Part of.The PART OF field defines the system to which the instrument or control system component is attached. System acronyms shall be as shown in TABLE II. The acronyms shall be consistent with those developed by 10.4.6. The PART OF data field shall not exceed 10 characters.

4.4.3Sub system.The SUB SYSTEM field shall be used, when applicable, to define the secondary system which interfaces with the primary system. The SUB SYSTEM field shall not exceed 10 characters.

4.4.4Location.This field defines the location of the instrument or control system component by compartment area. Compartment designations shall be standardized and abbreviated to minimized field usage. The LOCATION field shall not exceed 10 characters. Examples of typical abbreviations are as follows: a. MMRLL - Main Machinery Room Lower Level b. EOS - Enclosed Operating Station c. RDREQRM - Radar Equipment Room e. FASSTA1 - Fueling at Sea Station 1

4.4.5Location other,When instruments or control system components are not located in specific spaces, the location shall be identified by deck, frame and zone, Examples are as follows: a. 1-223-0 b. 1-151-1

4.4.6Sub location (SUB LOC).The SUB LOC field describes the approximate mounting location of an instrument or control system component within a compartment. The SUB LOC field shall not exceed 10 characters.

4.4.7Model number (MOD NO).This field shall contain the model number of the instrument or control system component and shall not exceed 15 characters.

4.4.8Range.This field shall define the full range capability of the instrument or control system component with the appropriate engineering units. For signal conditioners, the out put voltage of the unit or engineering units shall be defined. For instrument or control system components which measure negative and positive values, the first value given shall be the negative range of the unit followed by a dash-zero-dash (-0-) and then by the positive range in inch units and the pressure range in pounds per square inch, the vacuum range of inches shall be interpreted to be inches of mercury or as specified in the contract. The RANGE field shall not exceed 15 characters.

4.4.9Nomenclature.This field item shall define the instrument or control system component. See Table III for a sample listing. The NOMENCLATURE field shall not exceed 20 characters.

4.4.10Function Expanded (FUNCTION EXPD).This field shall define the parameter being measured by the instrument or control system component identified in the Nomenclature field. The FUNCTION EXPANDED field shall not exceed 45 characters.
