The measurer goes to the installation location of the steam trap 20 of the steam trap number 1 and firstly inputs various conditions such as the steam trap number, model, working pressure, and pipe size from the input unit 23. The input conditions are stored in the storage unit 25 of the signal processing unit 24 and displayed on the display unit 26. Further, these conditions are separately handwritten on a sheet 27 and attached to a name plate 29 attached to the inlet pipe 28 of the steam trap 20 or the like. Next, the vibration pickup 22 is pressed against the steam trap 20 to measure the vibration. A vibration signal of the steam trap 20 detected by the vibration pickup 22 is input to the signal processing unit 24 as an electric signal,
The processed measurement values are stored in the storage unit 25 of the signal processing unit 24 and displayed on the display unit 26. The above procedure is sequentially performed for other steam traps to be measured, and the measurement is completed. After completion of the measurement, the operation state is determined by printing out the data stored in the storage unit 25 or transmitting the data to the host computer.
