2.3.1.4 Item PRR

Setting the pulse repetition rate of the transmitted pulses.
Permitted values from 2 to 25 Hz.
The item PRR is indicated on the screen, see Figure 14.
For the increasing testing speed, please select the highest repetition rate of the transmitter pulses.
Note however, when inspection objects have small dimensions (the measurement base is less than half a meter) and low 

ultrasound attenuation value, the multiply reflected ultrasonic waves may cause ghost echoes and incorrect measurement 
values. In this case please reduce the repetition rate of the transmitter pulses, down to minimum.
