About RMS Displacement Meter APK
Table Of Contents
Description
Measures displacement by double integrating the acceleration from your device's linear acceleration sensor.Note, that this app requires a linear acceleration sensor in your device for it to work. Not all devices with an accelerometer will have the linear acceleration sensor capability.
Any drift or error in the accelerometer and/or other sensor readings is quickly magnified in the double integral, such that even a stationary device will quickly show displacement readings going wild. Therefore this App is for measuring alternating displacements. i.e we apply a drift reduction algorithm to remove any DC component and then measure the AC displacement by means of a Root Mean Square (RMS) value, or perform a Fast Fourier Transform (FFT) to obtain the frequency spectrum.
• Gauge to show the RMS displacement in the X,Y or Z directions, or its magnitude.
• RMS graph to show the gauge readings over time.
• Lower display shows time series data or a FFT from it.
• Peak indicators for the frequency spectrum.
• Save graph data to file.
• Units of cm, mm, m, inches or feet.
An example: Move the device in a circle along two of its axis. You should see two sinusoidal traces 90 degrees out of phase in the time series graph, determine the rotation frequency in the frequency spectrum and obtain an estimate of the diameter of the circle from the gauge or its corresponding graph (when set to peak to peak mode in settings).
Linear acceleration sensors will vary in sampling speed, resolution and accuracy from one device to the next. For indication only.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
