[Structure] A plurality of measuring devices 11 operating with a common power source are provided with a power carrier unit 15 and a data input / output unit 16 that superimpose a data signal on each measuring device side power line 13 and transmit / receive between the measuring devices 11. At the same time, a tap 12 having an insertion opening 18 through which a power plug 17 provided on each measuring instrument side power line 13 is connected to a common power source side external power line 20 is provided, and a data signal superimposed on the measuring instrument side power line 13 A block filter 19 for preventing the leakage of the power supply side external power line 20 is incorporated into the tap 12.
