Abstract
A vibration severity indicator has been developed which permits an operator to determine the severity of instantaneous vibration of a vibrating body in accordance with a vibration scale which is appropriate to the vibrating body. A DC ammeter is provided with a single scale divided into uniform segments. A selection switch is provided to permit the operator to indicate the category of the vibrating object so that the single meter scale will accurately reflect standards applicable to the category of the vibrating object. The result is accomplished by delivering an electrical signal corresponding to the instantaneous vibration level through a chain of resistance separated by contacts corresponding to the switch positions.
