Shock pulse measurement
Input data for LR/HR and LR/HR HD
Measuring points for the SPM techniques are normally
set up in Condmaster and then downloaded to Leonova.
However, it is possible to open the Leonova default file in
the SPM window and configurate all measuring parameters.
Select ‘LR/HR’ or ‘LR/HR HD’ and open with ENTER.
Transducer
Before starting measurements, make sure that the shock
pulse transducer you are using with your Leonova is
properly selected.
Default transducers for the shock pulse techniques are
set up via the transducer register. Default transducer
is the active transducer when ‘Portable’ transducer is
selected under ‘Measuring point data’. To select a default
transducer, see Chapter A page 15.
You can select other shock pulse transducers from the
transducer register (1) if you switch ‘Transducer’ from
‘Portable’ to ‘Remote’.
When using a DuoTech sensor all fields displays (2) that
normally apply to a vibration transducer. The actual data
for the individual transducer is written on its calibration
card. This data should always be input in the transducer
register. When several transducers are in use, they should
be marked to assurethat the readings are calibrated. Note
that measurements with DuoTech will be performed at
channel VIB-1.
For a normalized reading of bearing condition with the
Leonova default file, go to
MENU > ‘Measuring point
data’ and set the ‘TYPE’ and the ‘NORM’ number.
TYPE number
For ‘TYPE’ no. definition, see the table on page D:25.
Mark the line ‘TYPE’ (3), open it with the ENTER key, set
the number on the keyboard.

NORM number
The default setting for NORM is UN NORMALIZED, which produces the shock values LR and HR only.
If known, the NORM number can be input directly. Mark the line and open it with the ENTER key,
then select the number from the displayed list (4). The first choice on the list (---) also produces an
unnormalized measurement.
Given the rotational speed (rpm) and the mean bearing diameter, Leonova will calculate and display
the NORM number.
There are two alternatives for mean diameter. ‘Input ISO bearing number’ (5) opens a window (6) where
you set the
last three digits of the ISO number using the UP/DOWN arrow keys on the Leonova keypad.
‘Input diameter’ (7) opens the keyboard. Write the mean diameter, then edit RPM and write the rpm
on the keyboard.
The NORM no. will be displayed when the data input is complete.
