The manufacturer shall specify the rated operating conditions for the instrument as follows:
For the measurand:
The measuring range in terms of its maximum and minimum capacity.
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. |
For the mechanical and climatic influence quantities:
The minimum temperature range is 30 °C unless specified otherwise in the following chapters of this Annex.
The mechanical environment classes according to Annex I, point 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.
For other influence quantities (if applicable):
The rate(s) of operation.
The characteristics of the product(s) to be weighed.
The required performance and the critical change value are given in the relevant Chapter of this Annex for each type of instrument.
The conformity assessment procedures referred to in Article 17 that the manufacturer can choose between are:
For mechanical systems:
B + D or B + E or B + F or D1 or F1 or G or H1.
For electromechanical instruments:
B + D or B + E or B + F or G or H1.
For electronic systems or systems containing software:
