Abstract:
In a microprocessor-based instrument gauge comprising:B) a microprocessor comprising,i) input means for receiving data,ii) memory means for storing data,iii) processing means for processing data,iv) and output means for delivering processed data;C) means supplying gauge programming data to said input means and means supplying gauge signal data to said input means;D) said memory means storing gauge programming data that is used by said processing means to create gauge movement data at said output means;E) gauge movement drive circuit means operatively coupling said output means with said gauge movement for causing said gauge movement to be operated by said gauge movement data;F) said microprocessor being configured to store as gauge programming data, one or more various parameters relevant to operation of the gauge movement;the improvement which comprises:G) said means supplying gauge programming data to said input means comprising means supplying to said input means movement speed data defining speed at which the gauge movement is to move when the microprocessor acts on gauge signal data commanding a change in the position of the gauge movement;H) said microprocessor memory means comprising an EEprom that is programmed from said means supplying gauge programming data for erasably storing as one of said various parameters, the movement speed data supplied to said input means; andI) said processing means acting on the movement speed data stored in said EEprom of said memory means to create gauge movement data at said output means for causing the gauge movement to move at speed determined by the stored movement speed data when said processing means acts on gauge signal data commanding a change in position of the gauge movement.
