Vibration Measurement is device sensor log tool that enables you to monitor the vibration from your iOS Devices. You are able to preview the vibration data with graphs. Perfect for the casual user with user friendly UI. Features: ∙ Show device acceleration data in X, Y and Z direction. • Show device acceleration data by color. [X - Red, Y - Green, Z - Blue] • Can easily determine vibration direction. • Preview live acceleration data in a graph. • Lightweight app with a small size, optimized for everyday use. Display Data: • Device acceleration in [G] gravity • Maximum Amplitude in [mm] millimetre for each X,Y and Z axis • Average [G] data • Maximum [G] data • Maximum Amplitude in [mm] millimetre • Device Acceleration Data retrieve every 0.1 second [10Hz] • Time and Date show as a reference Formula: v = at Device velocity [v] = device acceleration [a] * time [t] s = vt Displacement/distance [s] = Device velocity [v] * time [t] 1 g-units = 9.8066 Metres per second squared Quick Start Guide: 1. Place your device on top of any surface. 2. Tap reset to start measuring the vibration. 3. You can enable screen recording to record the vibration process. Usage: • Measure the vibration of machine, motor or anything else. • Measure vibration in car/truck while driving/idling. • Record the vibration while riding/driving on difference road condition. • And many more depend on your imagination.
