In the latest version of "Vibroscope", the logarithmic scale graph display function has been added. You can change to logarithmic scale by tapping "log" button.

Logarithmic scale display (log)

This is a display mode to detect minute vibration.

In normal use, the graph does not become stable because the vibration does not converge. Graphing extremely small numbers can be affected by errors due to noise and temperature in the operating environment or time variations in sensor calibration.

In addition, if you move the terminal in the middle of measurement, the sensor correction may be wrong, and the acceleration value may converge to a fixed amount, so it is recommended to stop the measurement and re-measure.

Precautions

At the time of the first access to Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos".

In addition, in order to to continue the measuring operation in the background, "Settings > General > Auto-Lock" must be set to "Never". Please set this setting if you want to use the data logging.

Note

The xyz axis of the measurement display is based on the spatial axis of the acceleration sensor installed in the iPhone. In this application, 2 axis display coordinates and time axis coordinates are automatically determined by the terminal state.

- State with terminal vertically: 2 axis graph x - z, time axis y

- State with terminal in landscape orientation: 2 axis graph y - z, time axis x

- State with terminal liquid crystal facing the sky: 2 axis graph x - y, time axis z

Regarding the log data, since it records the data of the acceleration axis xyz itself, it is not related to terminal orientation.

With respect to measurable frequencies, the data sampling period from the acceleration sensor is Fast 100 Hz, Slow 40 Hz. It may be affected by the hardware environment and operating environment of the iOS system. In the FFT display, the frequency up to 1/2 of the sampling period is analyzed and displayed.

This application is not recommended for official measurement because there are variations and accuracy errors for each terminal and sensor. Also, if the vibration is large, errors may accumulate and proper display may not be possible. Therefore, please do not guarantee strict measurements, please use as an auxiliary tool to measure daily vibration level.

Please do not use while driving or operating the machine.

When measuring for a long time, battery consumption may be large.

The logarithmic scale graph is displayed very small numerical value, so it may be influenced by noise and temperature error in your environment or time fluctuation of sensor calibration.
