  • Page 20: Self-Check Mode

    4.4.2 Self-Check Mode By reversing the accelerometer vibration detection direction in the direction of gravitational acceleration (vertical) and checking the static acceleration of 9.8m/s (±1G), it is possible to determine if there is an accelerometer abnormality in a simplified manner. (1) Connect an oscilloscope or digital voltmeter to DCOUT.

  • Page 21: Averaging

    (6) Since the DCOT Sens is 30(m/s )/V, it is good if approximately 0.327V±5% is output. (7) Next, if the arrow mark of the accelerometer is set horizontal direction for ground, output voltage and acceleration value is approximately zero. Memo When using this mode, regardless of the measurement mode setting (Fig.4-1), the top display is acceleration, and the range is fixed at 20m/s rms (range change is disabled).
