EN 61143-1:1994

Electrical measuring instruments - X-t recorders - Part 1: Definitions and requirements

Applies to X-t recorders used for the measurement of voltage and current which measure and record analogue electrical quantities as a function of time. Also applies to non-interchangeable accessories and accessories of limited interchangeability (e.g. shunts, impedance-elements) if they are used with the recorder and the adjustments have been made for the combination. IEC 61143-1 and IEC 61143-2 cancel and replace EN 60484 (1974).

Elektrische Meßgeräte - X-t-Schreiber - Teil 1: Definitionen und Anforderungen

Appareils électriques de mesure - Enregistreurs X-t - Partie 1: Définitions et prescriptions

S'applique aux enregistreurs X-t destinés à la mesure d'une tension ou d'un courant qui mesurent et enregistrent des grandeurs électriques analogiques en fonction du temps. S'applique également aux accessoires non interchangeables ou à interchangeabilité limitée (par exemple shunt, élément d'impédance) s'ils sont utilisés avec l'enregistreur et si les réglages ont été effectués avec l'association des deux. Les CEI 61143-1 et 61143-2 annulent et remplacent la EN 60484.

Part 1: Definitions and requirements
FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
1)
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.
2) They have the form of recommendations for international use and they are accepted by the National
Committees in that sense.
3) In order to promote international unification, the IEC expresses the wish that all National Committees
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
4) The IEC has not laid down any procedure concerning marking as an indication of approval and has no
responsibility when an item of equipment is declared to comply with one of its recommendations.
This part of International Standard IEC 1143 has been prepared by IEC Technical
Committee No. 85: Measuring equipment for basic electrical quantities.
The text of this part is based on the following documents:
Six Months' Rule Report on Voting
85(Ca)15 85(CO)19
Full information on the voting for the approval of this part can be found in the Voting
Report indicated in the above table.

ELECTRICAL MEASURING INSTRUMENTS - X-t RECORDERS
Part 1: Definitions and requirements
1 Scope
This part of IEC 1143 applies to X-t recorders used for the measurement of voltage and
current which measure and record analogue electrical quantities as a function of time.
It also applies to a recorder whose chart scale lines do not correspond directly to the elec-
trical input quantity, provided that the relationship between them is known.
For the measurement of other electrical quantities, the relevant parts of IEC 51 also apply.
This part also applies to non-interchangeable accessories and accessories of limited
interchangeability (e.g. shunts, impedance elements) if they are used with the recorder
and the adjustments have been made for the combination. For controllers with electrical
outputs and containing electrical recorders, this pa rt applies only to the recorder and does
not apply to the control circuit.
rt does not apply to special purpose recorders or to special purpose devices (when
This pa
they are used as accessories) which are covered by their own IEC standards.
This pa rt does not cover safety requirements (for reference, see IEC 1010) and does not
contain either requirements for protection against environmental conditions or the relevant
tests. However, when necessary, tests under conditions approaching those of use may be
selected from IEC 68, to prove protection against environmental conditions.
Further, it does not contain requirements concerning the dimensions of instruments or
accessories (for the former, see IEC 473).

3 Definitions
The values of a.c. quantities given in this pa rt are r.m.s. values, unless otherwise stated.
For the purpose of this pa rt , the following definitions apply.
3.1 General terms
3.1.1 electrical measuring instrument: A measuring instrument intended to measure an
electrical or non-electrical quantity using electrical means.
3.1.2 analogue display instrument: A measuring instrument intended to present or
display the output information as a continuous function of the measured quantity.
3.1.3 electronic measuring instrument: A measuring instrument intended to measure
an electrical or non-electrical quantity using electronic means.
3.1.4 instrument with electric screen: An instrument shielded by conductive material
from the influence of an electric field of external origin.
3.1.5 accessory: An element, group of elements or device associated with the measur-
ing circuit of a recorder in order to confer specified characteristics on the recorder.
3.1.5.1 interchangeable accessory: An accessory having its own properties and
accuracy, these being independent of those of the recorder with which it may be
associated.
NOTE - An accessory is considered to be interchangeable when its rated characteristics are known and
marked and are sufficient to enable its errors and variations to be determined without using the associated
recorder. For example, a shunt whose adjustment takes into account the input current of the recorder and
which is not negligible and which is known is considered to be interchangeable.
3.1.5.2 accessory of limited interchangeability: An accessory having its own properties
and accuracy, which can be associated only with recorders for which ce rtain characteris-
tics are within specified limits.
3.1.5.3 non-interchangeable accessory: An accessory adjusted to take into account the
electrical characteristics of a specific recorder.
3.1.6 shunt: A resistor connected in parallel with a measuring circuit of a recorder.
NOTE - A shunt is generally intended to provide a voltage proportional to the current to be measured.
3.1.7 series resistor (impedance): A resistor (impedance) connected in series with a
measuring circuit of a recorder.
NOTE - A series resistor (impedance) is generally intended to extend the voltage measuring range of a
recorder.
1143-1 ©IEC -15 -
3.1.8 distortion factor (total harmonic distortion factor of a quantity):
r.m.s. value of the harmonic content
The ratio:
r.m.s. value of the non-sinusoidal quantity
3.1.9 ripple content of quantity
r.m.s. value of the fluctuating component
The ratio:
r.m.s. value of the d.c. component
3.1.10 recorder: A measuring instrument which records on a recording medium infor-
mation corresponding to the values of the measurand.
NOTES
1 Some recorders may incorporate indicating devices.
2 Some recorders may record information corresponding to more than one measurand.
3 Some recorders may also include interchangeable plug-in units. In this case, a recorder may have dif-
ferent specifications depending on the plug-in unit being used.
3.1.11 indirect acting recorder: A recorder in which the recording device is driven by a
motor or other device controlled by the measurand and using electromechanical, electrical
or electronic means.
3.1.12 drum chart recorder: A recorder in which the chart is wrapped as a single turn
around a cylindrical drum which is rotated by the chart driving mechanism.
disc recorder: A recorder in which the chart is a disc which is rotated by the chart
3.1.13
driving mechanism.
3.1.14 strip chart recorder: A recorder in which the chart is a strip driven by the chart
driving mechanism.
3.1.15 pen recorder: A recorder in which the record on the chart is made by a pen
supplied with ink.
3.1.16 stylus recorder: A recorder in which the record on the chart is made by a stylus
requiring no ink.
3.1.17 array recorder: A recorder in which the record is produced by energizing one or
more of a series of fixed elements.
NOTE - For example, these may be heated elements producing dots on thermal sensitive paper.
3.1.18 dotted line recorder: A recorder in which the record comprises a series of suc-
cessive impressions which may be points, numerals, etc.
NOTE - Recorders producing a series of dots which are so close to each other that they appear like a line
and the dotting time is short enough to be negligible, compared with the response time of the recorder, are
treated as continuous line recorders.
