Abstract:

A system and method that configures a measurement device to a correct measurement range. The system and method implements an autoranging technique, preferably in software, that automatically determines a measurement range based on a measurement. Once an initial measurement is received, the initial measurement is compared with the current measurement range. If the current measurement range is the correct measurement range for the initial measurement, then the measurement device is already configured at the correct measurement range. However, if the current measurement range is found not to be the correct measurement range, then a new measurement range is determined based on the initial measurement. A new measurement is then taken using the new measurement range to ensure the new measurement range is the correct measurement range. The process repeats itself by comparing the new measurement with the new measurement range to see if the new measurement range, is the correct range.
