3.3 DIALS

Dials are available for all standard ratios in both clockwise (D) or anticlockwise (S) configurations. Standard dials give a number which can be translated, by means of conversion tables, to the value of the set-up executed.

On request and for sufficient quantities, special dials with marks or customised graduations can be supplied to have a direct reading.
