3.1 Relative pulse-echo sensitivity relativepulseechosensitivity
From the specified reflector zoom back before the peak - peak-to-peak voltage applied on the probe - the ratio of peak voltage.
NOTE. pulser/receiver set single transmit/receive mode, the relative sensitivity of the pulse-echo the formula shown in Equation (1).
Srel = 20lg (Ue/Ua) (1)
Where.
Srel --- Relative pulse-echo sensitivity, dB;
Ue --- from the specified reflector zoom back before the peak - peak voltage, V;
Ua --- applied to the peak on the probe - peak voltage, V.
3.2 points angleprobeindex incident angle probe
Beam axis through the bottom surface of the probe point.
Note. This point is usually the side with the probe indicates scale reading.
