VR Mobile

A tool for vibration test and measurement professionals

VR Mobile connects to an ObserVR1000 dynamic signal analyzer or VibrationVIEW for live vibration test monitoring using a phone or tablet. It also contains engineering calculators, a light strobe, a noise SPL meter, and accelerometer. All of this from your mobile device!

INCLUDED FEATURES:

Connect to nearby ObserVR1000 Dynamic Signal Analyzer & DAQ

- Setup inputs, record and monitor data.

- Live FFT Analysis

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) can output based on the mass added to the system.

Unit Converter:

- Convert Acceleration, Force, Mass, Velocity, and Displacement 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.

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.

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 convenient flashlight during test setups.

- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.
