<p>An autoranging instrument having a user selectable range floor includes a controller for receiving data representative of an analog signal to be measured and a function selector for providing range floor information to the controller. In the autoranging mode, the instrument will uprange to a higher range if the measured value is above a predetermined uprange value, and downrange to a lower range if the measured value is below a predetermined downrange value only if the lower range is not below the range floor. A method of limiting display resolution includes the steps of setting a range floor, selecting a measurement range setting having a value at least as high as the range floor, upranging the instrument if the value of a parameter to be measured is above an uprange limit, and downranging the instrument if the value of the parameter to be measured is less than a downrange limit and the range setting of the instrument is above the range floor. <IMAGE></p> |
