Zusammenfassung:An integrated measuring device is provided to easily detect damage on a gas distribution line by measuring both DC and AC voltages as well as a ground resistance on the gas distribution line. An integrated measuring device includes first and second controllers(120,140), a measuring unit(130) and an LCD(Liquid Crystal Display) display(150). The first controller receives a key input and controls a printer module controller and a range controller. The measuring unit measures at least one of DC and AC voltages, an AC frequency, a DC current, and a ground resistance, and outputs the measured result. The second controller communicates with the first controller and receives the output from the measuring unit. The LCD display displays an output from the second controller.
