Vibrating Wire instruments are characterized by a nominal reading at zero pressure. This is intrinsic to vibrating wire instruments due to the nominal stress of the wire encapsulated internally. The resonant frequency of the wire vibration is measured in Hertz, or cycles per second, then converted to "digits", which is Hertz2 x 10-3. For
