Measurement Instrumentation With A Rolling Display

摘要

A method for displaying sensor readings in a measurement instrument having an array of display elements initially divides the range of interest of the sensor reading into a plurality of consecutive sub-ranges and determines a scaling function for displaying sensor readings for each sub-range. For each sensor reading, the appropriate sub-range is determined into which the sensor reading falls (where N is the number of this sub-range). The scaling function for the Nth sub-range is applied to display the sensor reading using N consecutive display elements. Optionally, the system may include a visual or audible indicator for the use when the display rolls from one sub-range to another. The display may also include feature indicating the peak sensor reading encountered.

1. A method for displaying sensor readings in a measurement instrument having a sensor with a range of interest and a display with an array of display elements, said method comprising:
dividing the range of interest of the sensor into a plurality of consecutive sub-ranges; determining a scaling function for displaying sensor readings for each sub-range using the display elements; and iteratively receiving a sensor reading and: (a) determining the sub-range in which the sensor reading falls, where N is the number of this sub-range; and (b) displaying the sensor reading on the display as a set of N display elements based on the value of the sensor reading within the Nth sub-range and the scaling function for the Nth sub-range.
