2.3.1.3 Item AVERAGING
Setting averaging factor.
Permitted values 1, 2, 4, 8, 16, 32, 64.
It is recommended to use averaging factor 16, as it is optimal in terms
of measurement time in relation to reliable results. In order to increase the
result accuracy and the reliability it is recommended to increase the averaging factor, especially when the signal-to-noise ratio is
not sufficient (strong attenuation, structural material noise or other background noise).
The item AVERAGING is indicated on the screen, see Figure 13.

2.3.1.1 Item MODE
Select the measurement mode:
- DIGITAL: measuring the velocity or the propagation time of the ultrasonic waves within the material and numeric indica-
tion of the result;
- WAVEFORM: measuring the velocity or the propagation time of the ultrasonic waves within the material and numeric
indication of the result and the signal waveform (А Scan plot);
The ENTER button: successive cyclical selection of operation modes.
The item MODE is indicated on the screen, see Figure 11.

2.3.1.2 Item RESULT TYPE
Selecting the type of the indicated result:
- TIME: measuring the time of the propagation of the ultrasonic
waves within the material.
- VELOCITY: measuring the velocity of the propagation of the ultra-
sonic waves within the material.
The ENTER button: successive cyclical selection of result types.
