• 17.020 Metrology and measurement in general

This British Standard gives recommendations for the design of scales and indexes of analogue indicating instruments in which an index moves in relation to a fixed array of scale marks to display the value of a measured quantity, or in which the scale moves in relation to a fixed index. Basic designs are given for scales for single, dual and multi-range fixed or portable instruments.

This British Standard is applicable to scales with:

1. black or dark coloured scale marks on a white or light coloured background;
2. white or light coloured scale marks on black or dark dials;
3. transilluminated scales.

BS 3693 can be applied in the design of both linear and non-linear scales.

No recommendations are given for the design of scales displayed on cathode ray tubes.

This British Standard can apply to non-electrical instruments.

NOTE The title of the publication referred to in this standard is given on the inside back cover.
