New standards have been established by the short wave therapy unit of the ULTRATHERM® 1008. Ideal energy source, which is a vacuum tube of high performance, is adopted by the device. This tube facilitates both techniques of the coil or induction field and the capacitor or condensor field to be implemented. A graphic display is provided by the device which ensures effective and convenient functioning, along with simplicity in usage. This graphic display, besides steering the user, offers suggestions of indication like pictograms offering appropriate electrode application and different program storage positions. The continuous display of the output power value, which is heat-effective, coupled with the dynamic matching indicator are the mechanisms by which the exclusive output power dosing operation enables greater accuracy in adjustment. This calls for total visual control of the operator over the therapy.
