MIL-STD-334 Displayed Messages For Automatic Test EquipmentThis standard sets uniform requirements for written or graphical information delivered to users of automatic test equipment ATE by computer-controlled output devices. Such devices include, but are not limited to, cathode-ray tubes, plasma displays, liquid crystal displays, printers, and plotters. This information, herein called displayed messages, may be directive and/or informative in nature. Displayed messages are included within the definition of official equipment publications.

MIL-STD-334B(TM) w/Change Notice 2

3.1.9  Target audience.  The target audience consists of the users of a given group of test program sets, defined by the Government in terms of specific job-related skills and reading level.

3.1.10  Technical manual (TM).  A TM is a publication that contains instructions for the installation, operation, maintenance, training and support of weapon systems, weapon system components, and support equipment.  TM information may be presented, according to prior agreement between a contractor and the Government, according to applicable TM military specification.

3.1.11  Test program (TP).  A TP is an organized sequence of commands or instructions directing operation of an automatic test system to determine the condition of a UUT or the ATE itself.  It evaluates the UUT's/ATE's performance and may also perform fault isolation.

3.1.12  Test program instructions (TPI).  The TPI provides information needed for testing (e.g., hookup, probe point locations, or other programmed operator intervention) which cannot be conveniently provided by the ATE under control of the TP. Appropriate contents are largely dependent on the ATE being used.

3.1.13  Test program set (TPS).  A collection of hardware, software, and applicable documentation used for testing, fault detection and isolation, maintenance, and any other evaluations of components and equipment.

3.1.14  Test program set documents (TPSD).  The TPSD consists of information necessary to enable the user to execute a UUT TP.  The TPSD consists of the TPI and SD.  The purpose of the TPSD is to provide information necessary to determine the operational condition and perform fault detection and fault diagnostics of a UUT on an ATE.

3.1.15  Unit under test (UUT).  Any unit or module subjected to ATE testing.

4.  GENERAL REQUIREMENTS

4.1     Style and format.

4.1.1  Style.  Messages shall be simple, short, and clear.  The general style (but not format) requirements of MIL-STD-38784 shall apply except when in conflict with this document or the physical constraints of the ATE

4.1.2  Format.  Format shall be uncluttered.  To the extent that format is not constrained by peripheral equipment or pre-existing system software, messages shall be arranged for ease of recognition. Information shall not be crowded so closely nor sequenced so rapidly as to interfere with any necessary operator response..

4.1.3  Format standardization.  Format standardization, such as for a specific ATE system or type of output device, is an important factor in operator usability.  Message formats shall conform to the detailed requirements in this document as well as any additional system-specific requirements imposed by the Government.

4.2.    Content coverage.  Messages shall be displayed for the following reasons:

a.       to provide instructions to the operator.
