  • Means for adjusting the zero point setting of a meter
    Patent number: 4206406
    Abstract: Adjustment of the zero point of an instrument is achieved by rotation of a rotary element extending through the casing of the instrument. The rotary motion of the rotary element is translated into a lateral motion of an intermediate adjustment element. The lateral motion is a side to side motion within the instrument relative to the sides of the instrument casing. The lateral motion of the intermediate element is in turn translated into a pivot motion of a suspension element of the instrument. The pivoting of the suspension element causes deflection and adjustment of the indicating element of the instrument from which readings of the instrument mechanism are taken.
