2.3.3 The MEMORY mode
In the MEMORY mode the screen is divided into two parts: in the upper part the measurement information is shown (thick-
ness, signal level, measurement method, velocity of the ultrasonic wave in the current material), in the lower part the informa-
tion on the previously recorded results (groups, cells of the groups and thickness measurement results) is shown (Figure 54).
To perform the measurements, install EMAT on the inspected object. The ultrasonic contact level indicator
and the measurement method indicator will be displayed in the upper left corner.
If the acoustic indication is on in the menu of the Mon-
itor, the changes of the readings will be accompanied by
quick signals.
The screens Monitor-INSIDE or Monitor OUTSIDE are
shown in the Figure 55 (the measurement result is dis-
played in red if the actuation condition of the monitor is
fulfilled, or in white if the actuation condition of the monitor
is not fulfilled).
Active keys:
: changes the velocity of ultrasonic
waves in the material.
If acoustic signals are emitted and the readings are
changing on the screen, keep the EMAT calm for 2-3 sec-
onds and wait for stable readings.
