Measurements were carried out by means of portable vibrodiagnostic measuring device Adash A4900 vibrio M. Vibrodiagnostic itself was realized as a walk-monitoring of machinery state according to corresponding technical standard ISO 10816-3:2009, and of limit values, which took place at regular intervals in the selected organization.
