VR Mobile - Sound & Vibration Testing

VR Mobile is a tool for vibration test and measurement professionals created by Vibration Research Corporation – Innovators in Sound & Vibration. It contains engineering calculators, a light strobe, a noise SPL meter, accelerometer, and remote control of VibrationVIEW and ObserVR1000 portable DAQ. All of this from your mobile device!

INCLUDED FEATURES:

Strobe Light and Flashlight
- Strobe your device's screen and/or flash LED from 1 - 30 Hz. Strobing helps one to see objects vibrating too fast for the eye to see.
- Turn your device's screen and/or flash LED into a flashlight; this makes a conveinient flashlight during test setups.
- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.

Connect to Device:
- Connect to nearby ObserVR1000 portable DAQ - setup inputs, record and monitor data.
- Remotely control VibrationVIEW from within the VR Mobile App (while on the same network).
- Start/Stop tests
- View graphs
- Adjust amplitude and frequency

Max Acceleration Calculator:
- Calculate the maximum amount of acceleration that a shaker (from a database or user input) can output based on the mass added to the system.

Unit Converter:
- Convert Acceleration, Force, and Mass units to and from common units.

Sine Calculator:
- Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.

Shock Calculator:
- Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.

Noise Meter:
- Measure minimum, current, and maximum dB from your mobile device's microphone. Note: A device must have a microphone in order to use this feature.

Accelerometer:
- Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes.
- Zero out acceleration to calibrate for an uneven surface.

Contact VR:
- See Vibration Research's building on Google Maps (or any other map application installed on your mobile device).
- Call, fax, or email VR directly from the app.
- Watch YouTube videos from VR.
- Visit VR's website.

VR Products:
- View VR's 9500 Revolution Vibration Test Controller, and the ObserVR portable DAQ.
