Rotary switch memory for digital multimeter

A digital multimeter, comprising:

• a rotary switch having a plurality of positions, wherein each of the positions is associated with a corresponding default primary measurement function and at least one of the positions is further associated with one or more non-default primary measurement functions;
• a processor for modifying an active primary measurement function associated with a particular position of the rotary switch, from (i) a default primary measurement function to a non-default primary measurement function, (ii) a non-default primary measurement function to a default primary measurement function, or (iii) a first non-default primary measurement function to a second non-default primary measurement function;
• and
• a rotary switch memory for storing modifications to an indication of the active primary measurement function;
• wherein, when the rotary switch is rotated away from and then back to the particular position, the processor retrieves the active primary measurement function from the rotary switch memory and causes the multimeter to perform the active primary measurement function.
