    A4404 SAB is a pocket size vibration analyzer which contains input connectors for sensors. It uses the same DSP board as VA5 Pro but it doesn't contain keyboard and screen. It must be connected with computer via USB. You need to install Virtual Unit application which is the same software used in VA5 Pro. Almost all functions described in this manual work both in the instrument and in the Virtual Unit.

  • Page 69: Fasit

    ADASH Adash 4500 – VA5Pro FASIT There is detailed description in the FASIT module chapter. If the FASIT is measured, the speed detection is done before the measurement itself (see the Speed detection chapter). Overall This is typical example of overall measurement. The RMS value of vibration velocity in frequency range 10-1000 Hz is measured.

  • Page 70: Iso 10816 Overall Measurement

    ADASH Adash 4500 – VA5Pro RMS and true peak measurement are generally independent. The only rule is that the peak value is always bigger then RMS value. Let's change the Avg to 8. The eight individual values (1 sec length) will be taken and the result will be the linear average of them ( RV = (V1+V2+...+V8)/8).

  • Page 71: Spectrum

    ADASH Adash 4500 – VA5Pro If you want to use this function you need to define the correct measurement parameters (RMS velocity measurement in 10-1000Hz range) and the group for machine. The ISO Machine Group is defined in the sensor dialog for the measured AC channel.
  • Page 72 ADASH Adash 4500 – VA5Pro Note! Cursor is displayed on both sides. Different colors are used. Both cursor values are displayed. Attention! The correct setting of channel A and B is critical for correct result. If this setting is wrong then the negative and positive side are interchanged.

  • Page 74: Time Signal Averaging

    ADASH Adash 4500 – VA5Pro Time signal averaging For averaging you need to set some trigger source in the Trigger Setting dialog, because only triggered time signals can be triggered. Then define the number of averages. You see the effect of averaging in decreasing of signal noise. The speed frequency is better seen. With the cursor values are displayed also totRMS and tot0P values.

  • Page 77: Orbit

    ADASH Adash 4500 – VA5Pro Orbit The A1 means, that the channel 1 is used for A orbit channel, similarly B2 means channel 2 is used as B. The position of A1 and B2 matches the sensor angles used for measurement (see Sensors definition). The knowledge of those angles enables to draw the correct shape of the orbit.

  • Page 78: Filtered Orbit

    ADASH Adash 4500 – VA5Pro Filtered Orbit Filtered orbit is built up from two order analysis readings. Correct sensors positions (angles) must be set for correct calculations as for standard orbit graph (see Sensors definition). You can switch displayed orders on or off in Graph Properties menu.

  • Page 79: Acmt

    ADASH Adash 4500 – VA5Pro The speed measurement is taken 8 times in every second. The value is evaluated from 3 tacho events in time signal. When the averaging is required, then more values is used. But keep in mind that only 8 values is taken in one second.

Such approach had one important benefit. You can analyze the signal again and again. When you need to make all required analysis in real-time, you are under time pressure. If additionally the for example runup can be run only once, the pressure is extreme.

    The standards should be rather determined for a narrow range of machines. The instrument uses the Adash limit values. These limits are not rewritten from any existing standard. It’s a result of 20 years of Adash engineering team experiences. It’s difficult to invent critical value definition which would be simple (that means not many parameters such as speed, power, bearing type, machine type and so on) and reliable.
