Example how to use the BCU scaling factor
In case of BCU measurements, the measuring result depends on
various factors, e.g. on the place of the pickup installation, on the
type of connection (e.g. tightening torque of the pickup) etc. The
consequence may be different measuring results with identical
machines and the same bearing condition units.
To enable a clear comparison of the single measuring points
(change of the bearing condition over a longer measuring period),
by means of the BCU scaling factor (parameters J19, J20) the
measuring results can be set to the same initial value (desired
value at the beginning of the measurement) for each measuring
point.
Carry out scaling
Input the scaling factor 1 for the respective measuring points.
Acquire the current measuring result.
From the desired BCU initial value and the current measuring
result of the respective measuring point, the BCU scaling factor
J19 or J20 is calculated with the following formula:
After the parameter input of all scaling factors, the re-spective
measuring point must display the desired BCU initial value.
