Vibroscope app analytics for December 18

"Vibroscope" is a powerful vibration analysis tool to measure various vibrations in real time using iPhone's acceleration sensor. It allows you to monitor by visualizing the very low frequency vibration such as inaudible by ear. This app can detect the amount of acceleration of vibration and display the two-axis coordinates in the horizontal direction and the time-axis waveform in the vertical direction. It is also equipped with the ability to analyze the frequency components of the very low frequency vibration by FFT analyzer. It can be measured by determining the horizontal or vertical direction to suit the attitude of the iPhone, so as to be available in a placement of the floor and desk or handheld. The measurement data can also be saved as a log file, so you can use it as a vibration data logger. Application Examples: - Analysis of the amount of acceleration and frequency components of the floor and walls during car traffic. - Measurement of howling vibration of audio equipment, etc. - Detection of acceleration and vibration of trains and automobiles. - Body balance check (horizontal body shaking detection). - Measurement of vibration acceleration during earthquakes, etc. (displayed value x 100 [GAL]) Features: - Measurement of vibrations (Main): acceleration values (m/s/s) - Real-time display: the horizontal direction (X-Y) - 2-axis vector plane graph, the vertical direction (Z) - the time-axis waveform. - Display scale switching of vibration acceleration graph (Linear/Log): Linear - linear scale display, Log - logarithmic scale display. - 3-axis composite acceleration display (Compo) - Peak level value display (Peak) - Switching of acceleration display (Instant/Average): Instant - instantaneous acceleration, Average - average acceleration per second. - Scaling of measurement display range - FFT analysis for 3-axis directional and composite acceleration, with peak frequency (FFT) - FFT graph display control (Axes/Axis-1/Axis-2) - Switching of sensor sampling period (Slow/Fast): slow, fast - Axis direction (Axis): Swapping the axis direction on the graph display during operation. - Measurement timer function: 1 sec to 1 hour - Start delay timer function: 0 - 20 sec - Reference level setting in FFT mode: 1e-6m/s/s, or 1e-5m/s/s - Snapshot of the measurement screen (Snap): Capture the measurement results and Timestamp to "Photos". - Data Logger: X-axis, Y-axis, Z-axis, saved in a text file (UTF8). It saves the measurement data, timestamp to LOG file. It can be exported by using "iTunes File Sharing". Important settings: - At the time of the first access to Photos after installing the app, you will be asked permission to access them from the iOS system. If you did not enable this setting on this time, it cannot be access from the app by privacy restrictions of the iOS. Please enable slide switch of the app in the access permission of the iOS setting, "Settings > Privacy & Security > Photos". - This app does not support to the background operation, so it needs to set on "Never" in the iOS setting, "Settings > General > Auto-Lock" for a long-time operation. Notes: - In general, there is variation and accuracy error by individual terminals and sensor devices of the iPhone, so this app does not recommend the use in the formal measurement. It is also possible that the accuracy error will accumulate if the vibration is too large, it may not be appropriate to display the measured value. - While driving a car or operating machinery, please do not use this app for safety. - The logarithmic scale graph displays very small numerical value, so it may be affected by noise and temperature error in your environment or time fluctuation of sensor calibration. - Log data can be transferred from an iOS device to a Mac or PC using the iTunes File Sharing feature. macOS Catalina and later can share files between an iOS device and a Mac using the Finder.
