ABSTRACT:
A digital multimeter (DMM) includes a microprocessor controller programmed for simulating operation of a plurality of DMM's by providing concurrent and substantially simultaneous displays of results of plural time-shared measurements. The microprocessor controls a single measurement and data conversion system to perform a plurality of separate measurements in a time-shared manner. Results of the plurality of separate, sequentially performed, measurements are concurrently displayed, substantially simultaneously, on a plurality of separate displays of the digital multimeter in accordance with the operation of the controller. The single multimeter of the invention thus simulates operation of a plurality of DMM's.
