Zusammenfassung:A digital multimeter can be monitored from a remote location via an on-board light source such as a backlight LED. The digital multimeter has memory, a processor operatively coupled to the memory, a light operatively coupled to the processor and the memory and a light sensitive sensor operatively coupled to the machinery and positioned proximate the light. The processor is configured to produce a first data signal containing information about the machinery, which is then modulated by the light so that the light blinks between an on state and an off state. The sensor is configured to detect the light on state and the light off state and convert the received light into a second data signal representative of the first data signal.
