VibroMatrix - Questions & Answers

Q:

How can I test VibroMatrix?

A:

On our download page we offer a free trial version of the VibroMatrix software. This is the full software package including all instruments. If you click the icon InnoMaster Trainer in your program menu, the software starts in the training mode. Instead of connecting the InnoBeamer hardware you may use simulated signals. The simulation menu opens after a right mouse click in the measuring channels window.

Q:

Can I calibrate VibroMatrix?

A:

Yes. The system includes a calibration function which allows to calibrate the entire measuring chain from the sensor to the display in one step using a vibration calibrator.

Q:

Can the system be operated for a longer period on an unattended PC?

A:

Yes. The VibroMatrix software is characterized by high stability. Particularly suited for long-term measurement are the instruments InnoPlotter and InnoLogger. Even after an abnormal system end the measurement will proceed normally. All you need to do is putting a link to VibroMatrix into the autostart folder of your PC and selecting the checkboxes "Save settings at end" and "Restore sensor connections" in the Workspace settings of the InnoMaster.

Q:

Why do I get unstable or too high results when I measure displacement?

A:

Set the high pass filter to at least 3 Hz, to suppress low frequency noise. Low frequencies are amplified by the integrators.

Q:

How can I export measuring results from VibroMatrix into other software?

A:

To make VibroMatrix as stable and simple as possible we decided to limit the number of export formats to a minimum. Most instruments with graphical output feature an export function for the graphics as Bitmap, PNG, EMF or text file.
The InnoLogger records the measured values on hard disk which allows to process them later by external data analysis software, for example FlexPro. The logger data can be exported either as binary file or in text format.

Q:

How can VibroMatrix display time graphs of vibration signals?

A:

Slowly changing vibration signals may be recorded as rms or peak values by the InnoPlotter in the way a strip chart recorder does. Real-time recording of the instantaneous value for short vibration events can be performed using the InnoScope.

Q:

Can I use VibroMatrix on several PCs although I have only one software license?

A:

Yes. The software key is installed inside the InnoBeamer hardware and will be recognized by the system as soon as you plug in the device, provided the VibroMatrix software was installed.

Q:

How many InnoBeamer devices can I connect to one PC?

A:

Tests have been made using up-to-date PCs with up to 20 InnoBeamer devices, i.e. 40 measuring channels. Several instrument windows can be opened for each measuring channel without data loss or delay. Such multi-channel systems are set up with active USB hubs.

Q:

How does offline measurement work?

A:

From version 1.5 VibroMatrix can save the real-time signal of the InnoBeamer on hard disk. You only need to enter a file name and to activate a checkbox in InnoMaster. After switching on a software instrument, VibroMatrix will save the raw signal on hard disk. This happens in the background while you measure as usual.
To recall stored data, start VibroMatrix as InnoMaster Replay. You will see a time bar graph for each channel that was saved.
As known from other play-back devices you will find the buttons play, fast forward, rewind and stop. After clicking the play button, all activated software instruments will start measuring with the data from hard disk.

Q:

Does the InnoBeamer L2 measure with the full sampling rate when both channels are active?

A:

Yes. Both channels are sampled with 10 kHz and have a bandwidth of 2 kHz.

Q:

Are there InnoBeamer drivers for other software?

A:

No.

How many InnoBeamer devices can I connect to one PC?

A:

Q:

The rotary speed detection of my InnoBalancer does not work reliably at higher speed. No rpm value is displayed.

A:

The photoelectric reflex switch needs a certain pulse length  for detection. If the reflective sticker is very small, the impulse duration may be too short. Use a longer strip of the material to cover a larger portion of the rotor circumference.

Q:

My photoelectric reflex switch does not work. The InnoBalancer does not display the rpm value although the LED at the rpm sensor flashes...

A:

The power supplied from your PC via the USB interface may be too low. This problem so far only occurred when a USB extension cable was used and the cable resistance became too high.

Q:

I want to see low frequencies in high spectral resolution but also observe higher frequencies. Why does InnoAnalyzer (Pro) not have a logarithmic frequency axis?

A:

An FFT produces equidistant spectral lines. If you plot them logarithmically, only few lines will appear in the range of lower frequencies. The upper frequencies are displayed in high resolution. The a.m. problem can be solved much better by means of the clone function:

• Display the entire frequency range in one InnoAnalyzer window.
• Open a second window by using the clone function.
• Display the lower frequency range with high resolution in the second window.
