F1SCHEDULE 1GAUTOMATIC WEIGHING INSTRUMENTS (MI-006) (Annex VIII to the Directive)
CHAPTER IRequirements common to all types of automatic weighing instruments
Rated Operating Conditions1
The manufacturer shall specify the rated operating conditions for the instrument as follows:
1
For the measurand:
The measuring range in terms of its maximum and minimum capacity.
1
For the electrical supply influence quantities:
In case of AC voltage supply | : | the nominal AC voltage supply, or the AC voltage limits. |
In case of DC voltage supply | : | the nominal and minimum DC voltage supply, or the DC voltage limits. |
1
For the mechanical and climatic influence quantities:
The minimum temperature range is 30 °C unless specified otherwise in the following chapters of this Schedule.
The mechanical environment classes according to Schedule 1A, paragraph 1.3.2 are not applicable. For instruments which are used under special mechanical strain, e.g. instruments incorporated into vehicles, the manufacturer shall define the mechanical conditions of use.
1
For other influence quantities (if applicable):
The rate(s) of operation.
The characteristics of the product(s) to be weighed.
2
Permissible effect of disturbances — Electromagnetic environment
The required performance and the critical change value are given in the relevant Chapter of this Schedule for each type of instrument.
Suitability3
3
Means shall be provided to limit the effects of tilt, loading and rate of operation such that maximum permissible errors (MPEs) are not exceeded in normal operation.
3
Adequate material handling facilities shall be provided to enable the instrument to respect the MPEs during normal operation.
3
Any operator control interface shall be clear and effective.
3
The integrity of the display (where present) shall be verifiable by the operator.
3
Adequate zero setting capability shall be provided to enable the instrument to respect the MPEs during normal operation.
3
Any result outside the measurement range shall be identified as such, where a printout is possible.
