The first line contains the actual g RMS value (re-triggered) and the proportion to initial value in %. Below first
line is horizontal bar,which always reaches a maximum level after procedure start.
You need to slowly start adding lubricant, while monitoring the height of the column on the display. Usually there
is not much going on in the beginning, which means that the lubricant is pushed toward the bearing, however it
is not there yet. At the moment when the lubricant reaches the bearing, the column decreases (usually its red
part disappears and only the green part remains). You need to add a little more lubricant, and if there is no
further decrease, you end the lubrication process.
If, at the beginning of measurement, value of vibrations and oilcan are green, then the signal from a bearing is
very low. We have either new or a very well greased bearing.
The recommendations are also displayed below the bar.
The acceleration spectrum is displayed in the bottom. You can look at the spectrum changes during the
procedure. You can find more detailed information about lubrication in the A4910-Lubri manual.
