1. A method for communicating with a multimeter, comprising:
- applying measurement signals at measurement terminals of the multimeter;
generating communication signals representing information to be extracted by the multimeter;
transmitting the communication signals to the same measurement terminals of the multimeter that were used to apply the measurement signals;
receiving the communication signals and the measurement signals applied to the measurement terminals in the same input circuit; and
extracting the information from the communication signals.
