Thiết bị đo, phán đoán và ghi lại sự rung động
* Chế độ xác định rung động( Chế độ giá trị Vibration, chế độ Envelope, chế độ giá trị Peak ,chế độ giá trị RMS (root mean square), chế độ hệ số Crest, Chế độ hệ số Form)
* Kế quả đo được so sánh với giá trị giới hạn trên/dưới cài đặt, và xuất tín hiệu phán đoán được thực hiện.(HH・HI・OK・LO・LL)
* Chức năng chuẩn đoán tần số sóng tín hiệu đầu vào nhờ FFT
* Lưu dữ liệu trên thể nhớ SD (các kết quả đo, các dạng sóng, chụp màn hình hiển thị FFT )
* Các kết quả đo và dữ liệu đồ họa có thể lưu trong bộ nhớ trong của thiết bị.

Vibration detect
  • Band pass filter :
  • High-pass filter :1 to 500 Hz
    Low-pass filter :1 to 500 Hz
    (Second-order Butterworth digital filter)
    * However, HPF < LPF
  • Judgment mode :
  • Vib. Val, Envelope, Peak, RMS, Crest, Form
    * Peak, RMS, Crest, and Form are calculated at each half-wave. Due to half-wave processing, a delay of 100mSec occurs in each output, such as judgment. Also, half-wave processing can be performed at 10Hz or more.
