PURPOSE: A digital power meter provided with a module type remote probing function is provided to subsequently display the amount of data on the display unit by pushing one button by once with connecting to 8 number of a gauge at maximum. CONSTITUTION: A digital power meter provided with a module type remote probing function includes a current detection sensor(1), a first buffer(2), a display unit(3), a microprocessor(4), an infrared rays communication unit(5), an RS485 communication unit(6), a wireless communication unit(7), a power line communication unit(8), a second buffer(9), an analog to digital converter(10), one button(11), a data collection device(12) and a gauge(13). The digital power meter stores the amount of usage inputted from various gauges, displays the amount of the usage and transmits the amount of usage when the data request signal is transmitted from the external remote data collection device(12). In the normal mode, the amount of used power is displayed, and if the one button(11) is pushed, 8 number of data are subsequently displayed at maximum. At the external data collection device, the data request signal is received, the data is transmitted to the external data collection device by using the communication module.
