    摘要: The display glass of an indicating instrument which is placed in front of a displaying front plate is heated by the absorption of radiating heat which is emitted by the heating of the displaying front plate by PTC electrical resistance elements which are advantageously fastened at the displaying front plate's rear side. By way of this device that is simple and cost-effective in regard to construction, fogging is removed on a display glass of an indicating instrument and a repeated fogging is reliably avoided.
