Pressure measurement system for judging power supply from terminal device to control section
Pressure measurement system has inside a main body to be mounted on an object to be measured: a sensor section; a control section processing an input from the sensor section and outputting a predetermined signal; a vacuum gauge provided with power supply circuit sections for providing the control section and the sensor section with power; and a terminal device being connectable to the control section, through a communication line, in a manner to be freely communicated with each other and being capable of supplying the power circuit section with power. The vacuum gauge is arranged to be able to judge the power supply from the terminal device to the control section. When power is supplied from the terminal device to the control section, the control section and the terminal device are connected together through the communication line so as to be freely communicated with each other.
