Main menu
The A4300 VA3 Pro instrument can be configured according to your requirements by choosing measuring modules. There are three free modules included in every VA3: Meter, Fasit and Strobo. Other modules are optional: Analyzer, Route, Balancer, Recorder, Run Up or Ultrasound.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Meter - Free Module!
The Meter module includes basic vibration measurement screens:
- Overall Vibration Values (RMS, 0-PEAK)
- FFT Spectrum
- Time Signal
- Frequency Bands
- Displacement
- Temperature

---------------------------------------------------------------------------------------------------------------------------------------------------------------

FASIT - Free Module!
FASIT (Fault Source Identification Tool) is an expert system for automatic detection of possible machine faults:
- Unbalance
- Misalignment
- Looseness
- Bearing faults

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Strobo - Free Module!
Switch on the stroboscope to visually “freeze” the machine movement and check its rotating parts. The speed of the machine can be detected.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Analyzer
Select the type of the measurement (from simple overall values through FFTs and time signals to more advanced measurements with Proximity probes such as Orbits), set up the measurement settings according to your requirements (frequency range, sampling, units etc.) and take all the predefined measurements simultaneously.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Route
The route module is used for day to day data collection of your factory machinery. Simply create your route tree with measurement points location in the DDS software (possible also in the free DDS version) and take the measurements regularly. Transfer the collected data to DDS software to watch the trends and analyze the data.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Balancer
The balancer allows you to perform one or two plane balancing job of rotating parts such as industrial fans, blowers, spindles etc.

------------------------------------------------------------------------------------------------------------------------------------------------------------------

Recorder
A unique measurement mode with unappreciated value. Recorder “records” the raw signal from the sensor, means raw signal from the machine. This allows to make a post processing of the signal later on your PC. You can play this record again and again and apply any measurement setting to it.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Run up
Similar to Analyzer mode where you can setup any measurement which you like. RunUp allows you to control the saving of data for example as soon as possible, or by speed change, time change etc.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

Ultrasound
Measurement of sound inaudible to the human ear – ultrasound. Typical application are air leak detection, electrical arcing or early bearing fault detection.
