2.3.2 FLAW DETECTOR mode

The instrument allows to operate with two strobes.
The strobes are used for setting the inspection zones, sensitivity levels, AFAS actuation, measurement of the flaw locations 

and signal amplitudes from the reflectors the required intervals.

Measurements can be performed both in automatic and manual modes.

Automatic 

mode is a measurement mode with one or two active strobes. The measurement of amplitude value of the 

point above the level of the strobe with the maximum amplitude within the strobe is being performed. When the echo-signal 
gets into the strobe time interval and when the amplitude of the signal exceeds the level of the strobe, the cursor will be au-

tomatically set into the actuation place and indication of the measured 
parameters will be performed. Additionally event of the signal exceeding 
the strobe level is accompanied by the sound signal and red LED blinking 
on the front panel of the instrument. If the signal is below the strobe, then 
neither registration nor measurement will be performed.

Manual

 mode is a measurement mode with the inactive strobes. 

The signal measurement is performed by moving the cursor by means of 
the 

 keys.

A marker having a shape of the shaded triangle will be displayed 

on the screen besides the cursor. The marker is always automatically 
set onto the maximum amplitude value amplitude of the signal within 
the strobe.

2.3.2.1 The screen in the FLAW DETECTOR mode

The screen in the FLAW DETECTOR mode is presented in the Figure 48.
The measurement results panel consists of three blocks (Figure 49)
Parameters displayed in the blocks depend on the operation mode 

of the instrument.
