computer. If you see that the display is slow, you should increase the query refresh period to e.g.
10 seconds.
The Sample grouping tells how many samples represent 1 pixel. If you set it to 1, the line
displayed represents exactly the signal, but it also goes at the same rate. This means very fast. If
you want to have time to see what's happening, you must increase this value. As a result, the
display is slower, and the line becomes an approximation of the signal – one pixel represents the
mean value of a group of samples – this has the same effect as applying a low-pass filter to the
signal. Behind the line, with the same color but lighter shade, the envelope of the signal (with the
true peaks) is drawn.
The Vertical zooming, or simply zoom, is exactly what its name suggests. A value of 1 means no
zooming; a value of 100 means that signal is multiplied by 100.

Background

This service provides a real-time display of the vibration level of the past (background file). This
presumes that background recording is active (see chapter 4.1.5).
The settings are the same as for the waveform display (Acquisition – see above). Additionally you
can move the display with the arrows. You can see at least one day back in time, probably more. It
depends on the period you set in the background settings. The simple arrows allow you to move
