• from reading and full scale

    from reading and full scale are accuracy specifications and are indicated in %.From reading is used for indirect gauges / below 1 mbar
    • % f.r. (from reading), i.e. % from current pressure reading
    • Example: ± 10 % f.r. when reading is 6.0x10-2 mbar: 6e-2 x 0.10 -> uncertainty ± 6e-3 mbar
    Full scale is used for direct gauges / diaphragm sensors
    • % f.s. (full scale), i.e. % from scale end
    • Example: ± 0.3 % f.s. with measuring range1 - 1200 mbar : 1200 x 0.003 -> uncertainty ± 3.6 mbar
