icture 54 Separated Signals
If you de-activate the auto-window –e.g. in order to separate signals
manually- please always check the measured speed of sound of the
separated signal. When having the (separated) desired signal within the
measuring window the speed of sound (parameter vs in diagnostic menu)
should be /- 20% of the expected speed of sound (e.g. when
measuring water at 20°C speed of sound should be within 1400….1500
m/s). If vs exceeds the expected values you most likely have separated the
wrong signal (e.g. pipe wall signal, then vs is showing speed of sound of
pipe material)
