1. A device for use in a metering device for measuring analyte levels in a sample fluid, said device comprising:

  • a housing;

    a controllable electronic driver;

    a memory coupled to the drive force generator, the memory including time and date of a last selected number of target tissue penetrating events, the memory including a time interval between alarm and target tissue penetrating event, and energy consumed by a penetrating member driver to drive a penetrating member into the target tissue;

    a plurality of penetrating members;

    a cartridge;

    a plurality of analyte detecting members positioned on an analyte detecting member support that is positionable in the cartridge and each of an analyte detecting member being associated with a penetrating member, each of an analyte detecting member providing an indicator of analyte levels in said sample fluid; and

    the analyte detecting member support being moveable in the cartridge so as to be able to move and present new, unused analyte detecting members in sequence with new unused penetrating members of cartridge.
