Abstract: Proposed is a device for the adjustment of parameters and/or operating conditions in electric shop apparatuses, in particular for transmitting frequency adjustment in transmitting modules for the transmission of measured values. For the power supply, the shop apparatus (31) is equipped with a chargeable storage battery (21), which can be charged via charging equipment (20) and a separate charger (22). Charging equipment (20) and charger (22) are designed for the additional transmission of adjustment signals from an adjustment unit (32). Furthermore, a control unit (16) is provided, which converts the received adjustment signals to electric switching signals for adjusting the respective parameter and/or operating conditions. With this, parameters and operating conditions can be adjusted without having to provide manual switches at the shop apparatus (31).
