The rules allow easy and accurate readings thanks to a 15x lupe (1962) for the 1972-Lite and 1972 series, and two lupes 10x equipped with dioptric regulation and mounted on a carriage to allow an easy slide for the 1972-S series; in this last series the two lupes are used to point on zero and on the final interest point.
