EMA transducer comes with a protective cap. The cap fitted on a transducer during the testing does not
affect the measurement accuracy.

Figure 1.2 –EMA transducer
The transducer of EMA Thickness Gauge includes the permanent magnet that entails specific
requirements to the device operation:
1. If the device is moved near a sharp metal object, operator should exercise care as it might get
magnetized to the transducer and harm operator.
Note –If the device is placed in proximity of a plastic magnet card, this might lead to the card
failure.
2. If the transducer is placed on a loose and relatively lightweight sample, operator should hold it
with hand.

RDC.ED.UT-3M-EMA.000 OM
Operating manual
EMA Thickness Gauge NOVOTEST UT-3M-EMA
Page. 7
3. If operator puts the device on a test object quickly and carelessly, it might bump against due to
additional acceleration caused by the magnetic field. To save the service life of the transducer,
it is recommended to place it on a test object smoothly and hold the device meanwhile.
4. It is recommended to put the device on the test object at a 60angle. Once the transducer
touches the test object, the transducer should be put upright.
1.6 Structure and functioning
The operating principle of the device is based on measuring the propagation time of an acoustic
wave through the test object. The measured time is converted into thickness using the preset velocity
of the ultrasonic wave propagation.
The acoustic wave is formed through electromagnetic-acoustic conversion directly on the surface
of the test object, bypassing the contact medium between the transducer and the test object. Due to this
conversion, the wave is not distorted in this medium.
The special data processing algorithm allows measuring the thickness of the test object correctly
in the presence of interfering factors such as metal anisotropy, multiple reflectors, and external noise.
The device eliminates the human factor, making thickness measurements fully automatic.
1.7 Operating modes
The device works in the following modes:
1. “MEASUREMENT”:
“AUTO”;
“MANUAL”;
“В SCAN”;
“CONTROL”;
“CALIBRATION”.

thickness gauge that is more than half of its maximum sensitivity.
If the magnetic field of radio noise is strong, the place of operation of the thickness gauge must be
shielded from the external magnetic field.
The device must be used by a person who has read this operating manual.
If the device id carried to the place of operation at sub-zero temperature and placed in a room with
a temperature above zero, it should be kept in a package for at least 6 hours to avoid the moisture
buildup.
2.2 Preparation for the use
2.2.1 Visual inspection
Before an operation, the device must be checked visually, and its parts, processing unit,
transducer, slots, and connection cable must be checked for damages.
2.2.2 Battery charging

The main menu of the thickness gauge consists of four sections:
1. “MEASUREMENT” –entering the measurement mode;
2. “ARCHIVE” –displaying of all the saved measurement results;
3. “SETTINGS”–in this section, the following parameters can be set: language, brightness,
color scheme, sound, type f., clear SD card, transducer, material, scale, time and date;
4. “INFORMATION”–displaying the information about manufacturer and the device.
2.3.2 “MEASUREMENT”mode
To enter the “MEASUREMENT”mode, choose the needed point using “ ” and “ ”, and
confirm the selection by pressing “ ”.
In the MEASUREMENT mode, the display is split into two sections: main and informational (top
part of the display) (fig. 2.5). The main section contains the working section of the mode, and the
informational section features the battery charge, connection to PC, SD card connection, and the
current time.
Figure 2.5 –Display of the thickness gauge
In “MEASUREMENT” mode, the thickness gauge can be operated in the following modes:
“AUTO”;
“MANUAL” mode;
“В SCAN” mode;
“CONTROL” mode;
“CALIBRATION” mode.
To switch the operating mode of the thickness gauge, press “ ”, and select the needed mode
by using “ ” and “ ”, press “ ” to confirm the selection. To navigate through the
parameters, use “ ” and “ ”, and use “ ” and “ ” to change the value.
Operator can change the resolution of the selected parameter by pressing “ ”. The selected
resolution is displayed by a special number ( , , , ) next to the value being changed.
2.3.2.1 “AUTO” mode
In this mode, the device automatically analyses the measured signals, selects the measurement
method, sets the parameters of the receive path, and displays the measured thickness value.

Operating manual
EMA Thickness Gauge NOVOTEST UT-3M-EMA
Page. 12
In the “AUTO” mode (fig. 2.6), the speed of ultrasound velocity in the test object must be set (the
measurement of the velocity). The ultrasound velocity should be set through the calibration, or
manually in the “SPEED” parameter (from 1000 to 9999 m/s).
Caution!
The device employs a transversal wave. The speed of propagation of transversal waves in steel is 3250
m/d.
Figure 2.6 –“AUTO” mode
When testing materials with high attenuation, big objects, and using a big sounding range, the
noise amplitude can be compared to the amplitude of the valid signal and the valid signal can be
difficult to see with strong noise. For these cases, the device implements averaging that can be done by
2, 4, 8, 16, 32, 64 and 128 signals.
2.3.2.2 “MANUAL” mode
In the “MANUAL” mode, the measurement and testing are performed, and also setting of the
device according to a specific task (fig. 2.7). All parameters for the settings of measurement are
divided into categories (tab. 2.1) and depending on the selected category, operator can set different
parameters.
