FOREWORD
1)
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
International Standard IEC 1187 has been prepared by IEC technical committee 85:
Measuring equipment for electromagnetic quantities.
The text of this standard is based on the following documents:
DIS Report on Voting
85(CO)22 85(CO)41
Full information on the voting for the approval of this standard can be found in the report
on voting indicated in the above table.
This International Standard cancels and replaces IEC 278: 1968 and IEC 278A: 1974.

DOCUMENTATION
1 Scope and object
This standard applies to the technical documentation to be supplied with electrical and
electronic measuring equipment for use in laboratories.
The object of this standard is:
- to achieve an acceptable level of uniformity,
- to prevent the use of incorrect expressions,
- to determine in general terms the basic contents and structure,
of the documentation supplied with the equipment in order to give the user sufficient
information on installation, use, safety, application, technical specification, principle of
operation, testing, servicing and lists of options, accessories and replaceable pa rts.
NOTE - This documentation may be contained in one manual or in a set of separate manuals covering the
various topics. In the latter case, each volume should contain a list of contents of the other volumes.
2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this International Standard. At the time of publication, the
editions indicated were valid. All normative documents are subject to revision, and pa rties

3 Definitions
For the purposes of this International Standard the following definitions apply. Some of
these definitions have been taken from the International Electrotechnical Vocabulary
(IEV), from IEC 359, or from other applicable IEC standards.
3.1 address: A unique code identifying the equipment when it is used in remote control
operations.
3.2 assembly: A number of basic parts or subassemblies, or any combination thereof,
joined together to perform a specified function.
3.3 adjustments: The process of making the equipment conform to its technical
specification.
3.4 block diagram: A relatively simple diagram to facilitate understanding of the
principle of operation. It is a diagram in which the main functional units of the equipment
(or part thereof) together with the mutual relationships between them are represented by
symbols or simple figures without necessarily showing all the connections.
3.5 calibration: All the operations for the purpose of determining the values of the
errors and, if necessary, other metrological properties of a measuring instrument. After
calibration and possible adjustment, the residual errors can be noted to produce correction
values if required.
3.6 circuit diagram: An explanatory diagram intended to facilitate the understanding of
the details of the operation of the equipment. It shows by symbols all the components of
the equipment (or part(s) of the equipment) and all their interconnections, particularly all
the electrical connections.
1187 ©IEC: 1993 - 11 -
3.7 communication protocol:
A formal statement of the procedures (a set of rules)
that are adopted by the interconnected equipment to ensure an orderly and correct
transfer of information between the devices.
3.8 component location illustration: A diagram or photograph in which the elements
are displayed in a possibly simplified, but well recognizable form, showing their places in
the equipment or subassemblies.
3.9 correction table or graph:
Table or graph containing data which provide for
corrections on equipment displays, taking into account errors found during calibration, but
which shall be disregarded when assigning a class index (accuracy) to the equipment.
3.10 data bus (instrumentation bus): A set of signal lines used by an interface system
to which a number of instruments or parts of an instrument are connectable and over
which messages can be carried.
3.11
preset value (default): The initial settings of the equipment or function, for
example, after a "power-on" or a general clear action.
3.12 device dependent codes: The set of codes, specific to a given equipment,
intended for sending and receiving messages to and from the outside world.
3.13
error codes: Codes indicating the possible causes of abnormal operation such as
malfunctioning of the equipment, programming errors or measuring errors.
3.14 flow cha rt: A graphical representation of the definition, analysis, or solution of a
problem in which symbols are used to represent the operation, data flow, sequence of
events and decisions related to the operation of the equipment.
functional drawing of moving parts: A drawing in which, by means of perspective
3.15
and/or conventional pictures, symbols, signs and inscriptions, the functioning of the
moving parts and mechanisms belonging to the equipment is identified and, where
necessary, explained.
3.16 instruction card: A card listing, in condensed form, the operating instructions for
manual and, if applicable, remote control.
3.17
interface: A common boundary between one system and another, or between parts
of a system, through which information is conveyed.
3.18 manual control: A method whereby the equipment is set by means of its local
(front or rear panel) controls in order to enable it to perform its tasks (also called local
control).
3.19 operating manual: A technical document, which may be in more than one volume,
containing the information necessary for the proper operation and application of the
equipment and for a basic understanding of its functions.

Measuring equipment which performs specified
operations on command from the system and may transmit the results of the performed
function to the system.
3.23 remote control: A method whereby the equipment is programmable via its
inte rface connection in order to enable it to perform its tasks.
3.24 repair: Work carried out on equipment which is no longer functioning, or which no
longer complies with its specification, with the purpose of restoring its specified
pe rformance.
3.25 service manual:
A technical document, which may be in more than one volume,
containing the information necessary for both maintenance and repair of the equipment.
3.26 signature analysis: A technique which generates compressed, normally four-digit,
