Abstract
A digital multimeter with a rotary switch having a plurality of positions, each of the positions corresponding to a primary measurement function to be performed. An LCD displays secondary functions or modes corresponding to the positions of the rotary switch and values determined by performing one of the measurement functions. The multimeter includes default functions for each position of the rotary switch that may be changed to other functions or modes. When the other functions or modes are set in a first position, the rotary switch is moved to a second position, and returned to the first position the multimeter restores the functions and/or modes set when the rotary switch was previously in the first position.
