1.6 Design and functioning
The principle of operation of the hardness tester depends on the type of the connected probe.
When using the Leeb probe, the hardness is measured by the dynamic method of Leeb, and when
using the UCI probe - by the ultrasonic contact impedance method.
The dynamic method of measuring hardness is used to control:
hardness of objects weighing more than 5 kg and wall thickness of more than 10 mm;
hardness on solid products, products with coarse-grained structure, forged and cast
products;
hardness, if minimal surface preparation is required.
Ultrasonic contact impedance -resonance method for measuring hardness is used to measure:
hardness of objects with low mass (from 0,1 kg) and wall thickness (over 1 mm);
hardness on products with a glossy surface (if the minimum print size is required);
hardness of the surface hardened layer at the inspection site.
1.6.1 Modes
The hardness tester works in the following modes:
1. <MEASUREMENTS>:
Main scales mode (HRC, HRB, HB, HV, HS, HL, MPA);
User scales mode (U1, U2, U3);
A mode of measurement of hardness of basic materials (steel, alloy steel, stainless
steel, gray cast iron, high-strength cast iron (<CHARG>), aluminum, brass, bronze,
copper);
A mode of measurement of hardness of user materials (<USER 1>, <USER 2>);;

1.6.2 Leeb measurement principle (Leeb)
The dynamic principle probe (rebound method) is a separately executed device connected to the
electronic unit by means of a cable.
The principle of measuring hardness is based on the determination of the ratio of the velocities of
impact and rebound of the striker inside the probe. Carbide ball is located at the end of the impact
body, directly in contacting with the material at the time of impact. Inside of the impact body is a
permanent magnet. The striker, after pressing the trigger button, is ejected onto the surface to be
measured by a pre-charged spring. While this, the striker moves inside the inductor coil and, with its
magnetic field, induces an electromotive force (EMF) in it. The signal from the output of the induction
coil is fed to the input of the electronic unit, where it is converted into a hardness value of the selected
scale and displayed.
This method is particularly suitable for hardness measurements on solid products, coarse-grained
products, forged and cast products.
The design of the dynamic probe allows user to make more measurements per unit of time, and
working with it does not require special skills, such as with an UCI probe.
1.6.3 Ultrasonic Contact Impedance method
Ultrasonic probe (UCI ultrasonic contact impedance method) is a separately executed device
connected to an electronic unit by means of the cable.
The probe basically uses a steel rod with a diamond pyramid at the end, which is an Acoustic
Resonator (Oscillating Rod) of the built-in self-oscillator of ultrasonic frequency. When the diamond
pyramid is introduced into the tested object under the action of the fixed load of the calibrated spring,
the resonant frequency of the resonator changes, determined by the hardness of the material. The
relative change in the frequency of the resonator is converted by the electronic unit into the hardness
value basing on the selected scale and displayed.
NOVOTEST.ED.Т-UD3.000 OM
Operation Manual
Hardness Tester NOVOTEST T-UD3
Page. 13
This method is suitable for hardness measurements on products of various weight and thickness,
and especially on finished products with a glossy surface, since it leaves a minimally visible imprint
after measurements.
The design of the ultrasonic probe makes it possible to carry out measurements in hard-to-reach
places (for example, the surface of gear teeth, etc.), as well as on thin-walled structures (eg. pipelines,
etc.) that can not be measured dynamically by the probe.
It should be taken into account that the result of the measurement by the UCI method depends on
the Young's modulus of the tested product.
1.7 Means of measurement, tools and accessories
The efficiency of the device is evaluated by checking the measurement of hardness on the
reference hardness test blocks, reference hardness blocks should be grounded to the grinding plate
weighing not less than 5 kg through a layer of grease. Mismatch readings must not exceed the
permissible error (Table. 1.2). If the permissible error is exceeded, calibrate the instrument in
accordance with 2.3.7.
The manufacturer should make adjustment and tuning of the device in the case of faults.
1.8 Marking and sealing
On the front panel of the device is a symbol of the device with the trademark of the manufacturer.
On the rear panel, under the battery compartment cover the serial number is printed.
1.9 Packing
The electronic unit and the probe are delivered in a package (case), excluding their damage during
transportation.
To avoid mechanical damage to the cable and connectors of the device, it is necessary to
disconnect the sensor from the device before packing it into the package.

2 INTENDED USE
2.1 Operational limitations
Operation of the device should be carried out under the influence of factors and taking into
account the parameters of the monitored objects in accordance with the specified technical
characteristics, and the device must be used within its technical characteristics.
Only qualified personal, familiar with the operation manual is allowed to use with this device.
After transporting the device to the place of operation at a negative ambient temperature and
placing it into a room with a positive temperature, it is necessary to keep the product in its packaging
for at least 6 hours in order to avoid failure due to condensation of moisture.
2.2 Preparing the device for use
2.2.1 Visual inspection
Carry out visual external inspection of the device; make sure that there are no mechanical
damages to the electronic unit, the probe, the connector and the connecting cable.
2.2.2 Installing the batteries
Install the batteries into the battery compartment by unscrewing the two fixing screws and
removing the battery cover. Batteries are to be installed according to the polarity indicated on the
device (Figure 2.1). Close the battery compartment cover and screw in the screws.

2.2.3 Connecting the Probe
Using the connecting cable connect the probe to be used to the probe socket on the electronic unit.
Connect the connecting cable making sure that the red dot on the plug and socket are in line (Figure
2.2).
Figure 2.2 - Connecting the probe
2.3 Using the device
2.3.1 Preparing the object of testing
Prepare the needed surface area of the material, removing moisture, contamination (oil, dust, etc.),
grease, scale, oxide film, and rust from it. Grind it with a grinder or sandpaper and wipe the ragged
surface.
The roughness and radius of curvature of the measured surface, as well as the weight and
dimensional characteristics of the product, should correspond to the parameters specified in the
technical characteristics of the hardness tester (Table 1.3), consider the type of probe (UCI or
dynamic) used for the measurement.
The results of measurements by the UCI method are affected not only by the properties of the
metal during plastic deformation, but also by the Young's modulus (modulus of elasticity). It entails
the need to adjust the instrument when working with products that have the Young's modulus different
from the Young's modulus of structural and carbon steels.
To determine the additional error presence, compare the results of measurements with the
measurements of the hardness of the static measurement principle. If the difference in the results does
not exceed the error of the instrument, it means that it is possible to carry out measurements on the
characteristic written in the memory of the instrument upon delivery. If the measurement error exceeds
the required accuracy, a two-point or one-point calibration of the device on the product or sample (see
2.3.7) is necessary.
If the product or measure of hardness does not meet the requirements of Table. 1.3 (mass and / or
thickness), the instrument will make measurements with additional error. It will be as big, as the
NOVOTEST.ED.Т-UD3.000 OM
Operation Manual
Hardness Tester NOVOTEST T-UD3
Page. 16
discrepancy from these requirements is. The sign of the additional error may be, either positive or
negative, depending on the specific conditions.
The reason for the additional error emergence is the parasitic oscillation at the point of contact of the
indenter with the material at the moment of measurement. This is due to the vibration of the whole
product, if its weight is low, either because of deflection product if its thickness is small.
To determine the presence of additional error compare the measurement results with the results of
measurements of hardness using a bench hardness tester.
There are three methods to eliminate the additional errors.
The first method – to make the one-point or two-point correction of the current user setting in
accordance with clause 2.3.7. It is used if an additional error of not more than 15%, and the results in a
series of measurements are stable.
The second method – by eliminating parasitic oscillations gripping articles in a vise (clutches mass
should be clearly greater weight than the indicated in Table 1.3.). To prevent damage to the product is
allowed to use on overhead jaws of a softer metal vice.
The third method (recommended) – eliminating parasitic oscillations by grounding the object to a
massive polished plate. The plate should have roughness Ra not greater than 0.4 microns, obviously
greater weight than indicated in Table 1.3, non-flatness not less than 0.005 mm, a Young's modulus of
the material from which the plate is made should be close to the Young's modulus of the product. The
lower portion of the object is to be plane-polished with a roughness Ra not greater than 0.4 microns
and flatness no more than 0,005 mm. To install the product on the plate on its support surface a thin
layer of lubricant to be used. The product is to be grinded to the plate surface so that between the
surfaces and plates were no stains of even small air gaps. Grind must be tight enough so that the
product and the plate form a single monolithic.
Also, the cause of the error may be fingerprints of different depths. The values of these depths
may differ, depending on the measured hardness (Table 2.1.). It is recommended to measure the
hardness of the layer that is 20 times greater than the indentation depth. For the reasons stated above,
the measurement result is influenced by the properties of the surface layer. The depth of penetration of
the indenter into the material is substantially smaller than with the instrument of the static type: Brinell
and Rockwell. This can lead to misalignment of the measurement results in the case of hardening,
decarbonized layer, burn marks, and martensitic spots.

Hardening can be formed in the surface layer after the turning and milling and rough polishing.
The softer the metal, the greater the difference between the hardness of the top layer and the inside.
Decarbonized layer with low hardness is formed by the high-temperature heat treatment. This may
be hardening, normalization, hot rolling, forging, etc. The thickness of this layer is typically less than
0.2 mm.
When heat treated steels with good hardenability by the average hardness in the surface due to
overheating may occur martensitic stains with high hardness.

coefficient of variation of a random variable;
number of measurements.
Fig. 2.22 shows an example of work in the statistics mode, in which the table lists all the
parameters of a series of measurements.
Figure 2.22 - Statistics mode
2.3.6.4 Intelligent mode
The accuracy of the instrument is influenced by many external factors, which introduce an
additional error in the measurements. It can be:
jiggle of hand;
move of the tested object;
swaying of the probe;
surface cleanliness;
surface roughness.
For ultrasonic probe additionally:
the load is too short or too long;
probe is pressed too lightly or too hard;
low batteries.
Intelligent mode allows to determine the overall sequence of measurements. Select the first three
series of measurements that do not exceed the specified tolerance. After that, the following
measurements, which exceed the specified tolerance, will be excluded from the series, and will not be
taken into account when calculating the average value of the measured hardness from this series
(Figure 2.23).

To set the tolerance for Intelligent Mode, go to the <Settings> menu, set the tolerance values in
percentages from 1 to 10 (Figure 2.25).
Figure 2.25 - Setting the tolerance for the intelligent mode
Also, in order to reduce the influence of external factors in the device settings, you can include the
Kalman filter or the Median filter.
In order for the instrument readings to be most accurate, the user needs to select the proper filter
for the particular case.
Kalman filter
The Kalman filter is a linear filter, which is used to obtain the truest value. Also, the Kalman filter
can be defined as a filter giving the least mean square error.
NOVOTEST.ED.Т-UD3.000 OM
Operation Manual
Hardness Tester NOVOTEST T-UD3
Page. 28
The main idea of the filter is to find the coefficient C that will correct the received value so that it
would differ from the real value the least.
Kalman filter is recommended to be used when measuring on a product with heterogeneous
structure, where hardness jumps can be observed, which must be taken into account when assessing
the hardness of the product. Kalman filter can reduce the influence of external factors on the
measurements, while not distorting the jumps in hardness.
Median Filter
The median filter - is a nonlinear filter that is applied to signals subjected to pulse interference.
The medial filter is recommended for measuring homogeneous products, in which should be no jumps
in the value of hardness. If, due to external factors, the probe changes the readings, the filter will
smooth it to the normal value.
2.3.6.5 SIGNAL
The mode is active only for the dynamic probe and shows the voltage. M - represents the
maximum value that corresponds to the signal (Figure 2.26).

2.3.7 Calibration
2.3.7.1. Calibration of scales
To calibrate the probe, 3 samples of material with known hardness value are needed. The hardness
range should be wider than the hardness of the material that will be measured in the future (the value
should be a maximum or more, a minimum or less, and an average).
1. Select <CALIBRATION> from the main menu. Each cell in the table corresponds to a specific
calibration scale for a particular material (Figure 2.27). All calibrations can be calibrated for
any materials and any scales, and are thus separated only for the systematization of a set of
calibrations.

2.3.7.2 User (additional) graduation
Each of the stored calibrations can be further adjusted.
The user grading of the hardness tester in the inter-service calibration interval is recommended in
the following cases:
if, while checking the hardness tester with the reference hardness measure, its readings are
stable, but differ from the value of the reference hardness measure;
after long-term storage (more than 3 months.);
after intensive use;
if the operating conditions (temperature, humidity, etc.) change significantly.).
To graduate the hardness tester, one (one-point graduation) or TWO (two-point calibration)
reference hardness measures with the maximum and minimum values are required at the controlled
portion of the hardness scale.
For example, we have two samples of steel with a known hardness value of HRC, and the
instrument shows a stable deviation when measuring the hardness on it.
