摘要： PROBLEM TO BE SOLVED: To perform a calibration operation and the control of maintenance data according to a pressure transmitter at the field occasionally for rationalization and saving power, by incorporating a pressure calibration control unit and a communication unit in a handy personal computer in a portable structure, and automatically performing a calibration operation while operating the units at the field. SOLUTION: An automatic pressure-adjusting device 1 incorporates a communication unit 12. A communication unit 17 of the handy personal computer 2 communicates, for example, calibration data and measurement values with the automatic pressure-adjusting device 1. A pressure calibration control unit 18 of the handy personal computer 2 takes out current and past calibration data of a pressure communication equipment 3 being retained in a calibration database 20. Pressure being applied by a calibration control part 19 is determined, and a set pressure is transmitted to the automatic pressure-adjusting device 1 via the communication unit 17, thus setting calibration data on the spot and retaining data after calibration operation without returning to a measurement room for the pressure transmitter 3 being mounted to the field.
