7.1. Upgrade Measurements
In addition to the above standard delivered measurements it is possible to upgrade VIBER
X5 MkII™ with additional programs. VMI continuously develop analyzing programs for your
instrument, check VMI download page for information on available programs.
Below are some examples of programs to upgrade your VIBER X5 MkIII™:
Synchronous Averaging
This application is useful to reduce background noise in spectra of complex
signals. When you have spectral peaks which are very close to the harmonics of
the machine speed it will average out peaks that are not whole number multiples (non
synchronous) of the running speed, and the signals that is synchronous with the trigger will
be emphasized.
MCSA (Motor Current Signature Analysis)
Motor Current Signature Analysis (MCSA) is used to determine the operating
condition of AC induction motors without interrupting production. MCSA
operates on the principle that induction motor circuits can, in essence, be viewed as a
transducer. By clamping a Hall Effect Current sensor on either the primary or secondary
circuit, fluctuations in motor current can be observed.
7.1.1. How to Upgrade
To upgrade your VIBER X5™ with additional
1
st
Send the serial number (SN) of your instrument (starts with X5 followed by four digits,
example: X50001) to VMI.

nd
Place the file you receive in the SYSTEM folder on the VIBERX5™ SD Card
3
rd
Go to Update (From Main menu select Settings and Update) and press (Ctrl) + (F1)
(LICENSES), the installed licenses are showed in the Update Software menu.
If you have an old Program (Firmware) file in the instrument, you may also need to update
the program file.
7.2. Total Value
The Total Value is used to get a fast judgment of
the severity of the vibration. It is also used to
analyze the largest vibration on a machine or
structure by moving the transducer to different
positions and directions.
From Main menu select, Measure and Total Value .
Total Value RMS, example: If the simultaneous vibration caused by imbalance is (4 mm/s),
by misalignment (2 mm/s) and by the gear mesh forces (5 mm/s) then the total vibration
will be 6.7 mm/s. Total Value =
s mm / 5 , 6 ) 5 2 4 (
2 2 2
  
Notice, if you take away the entire imbalance, total value will be = 5, 4 mm/s
