An induction heating unit adjustment device for an adjustment of at least one field shape of an alternating field of an induction coil of an induction heating unit, having a field forming unit which is configured for a shaping and/or shielding of the alternating field generated by the induction coil, the field forming unit
- comprising an exclusively manually operable field former receiving unit, holding field former elements movably and/or exchangeably in and/or on the induction heating unit
- and
- comprising movably supported field former elements, forming at least a portion of an iris aperture with an iris opening that is variable in size
- or
- comprising different exchangeable field former elements, forming at least a portion of an exchangeable disk of a plurality of exchangeable disks which are exchangeably insertable in the field former receiving unit and which in each case have a differently sized opening, the induction heating unit adjustment device further having an electronic sensor unit, which is configured for sensing a type and/or a position of the field former element that is held in and/or on the induction heating unit by the field former receiving unit, and for outputting an electronic measurement signal,
- wherein the indicator unit comprises at least one color-changing element, wherein the indicator unit is configured to indicate a deviation from a pre-selected type of the field former element and/or a deviation from a pre-selected position of the field former element by means of a deviation signal, and wherein the electronic sensor unit is configured to monitor an adjustment process that influences the type or the position of the field former element and, depending on a matching of the type or the position of the field former element with the pre-selection, to output the deviation signal or the matching signal by means of the color-changing element.
