5 Principle of operation

5.1 Rebound method

Rebound probe consists of an impact body and the capture. The impact body has a carbide tip and
a permanent magnet for generating a voltage pulse; the impact device has a spring mechanism for
loading and impelling the impact body, and an induction coil for detecting the magnet in the impact
body. In the rebound hardness testing method, the speed variation caused by the impact of the
impact body against the material surface is measured.
The impact energy is adjusted via the spring for the measurement. The impact body contained in
the tube of the impact device is impelled against the test surface by means of the release button. In
the course of this, the magnet of the impact body induces in the coil a voltage signal whose height
is proportional to the impact phase speed. The impact causes a plastic deformation of the material
and a permanent spherical indentation is produced in the surface. This plastic deformation leads to
a loss of energy of the impact body and thus to a lower speed after the actual rebound phase.
The speed ratio is determined exactly at the moment of impact/rebound by means of the special
signal processing. The speed ratio is therefore unaffected by the impact direction. As opposed to
this, other rebound hardness testers require presetting of the impact direction in fixed steps
(influence of gravitation on the speed ratio) - which constitutes a considerable disadvantage with
frequently changing test positions.

5.2 UCI method

The Vickers diamond is fixed to the tip of a round metal rod. This metal rod is excited, to its resonant
frequency of approx. 78 kHz, into longitudinal oscillations. When the Vickers diamond contacts the
sample surface, the resonant frequency will change. This change happens in relation to the size of
the indent area from the Vickers diamond. The size, in turn, is a measure for the hardness of the
tested material. Resonant frequencies can be measured very accurately. This is why the UCI
method is suited to make the evaluation of Vickers indents, and thus of the complete test procedure,
so much easier and quicker.
There are also two additional advantages:

- the measurement is made under load. (No impairment of the measurement due to elastic
resilience);

- the hardness measurement is based on the area of the indent and not on the length of the indent
diagonals.
The measurement is thus less affected by surface roughness; even gunmetal-finished surfaces can
be measured.

Concerning the UCI method, the measurement value is also dependent on the Young’s modulus of

the material.

6 Preparations for operation

6.1 Battery supply

The hardness tester PCE-3000U / PCE-3000UL is powered by two 1.2 V Ni-MH batteries (1000

7.2 Selection of measurement method

7.2.1 Rebound method

This method is appropriate for:

- testing objects weighing more than 5 kg and a wall thickness more than 10 mm;

- massive products, products with a coarse-grained structure, forged and cast products;

- testing objects with minimal preparation of the surface.

7.2.2 UCI method

This method is appropriate for:

- testing objects with low mass and small wall thickness;

- testing objects with a glossy surface (with special requirements to the minimum size of the
imprint);

- surfaces of the testing objects with hardened layers.

8 Operation

8.1 Preparation of the test material

The surface must be clean and free of oil, grease and dust.
The surface roughness of the material should meet the requirements of a specific probe (paragraph

3.6).

8.2 Features of the measurement methods

8.2.1 UCI method

Distinct reading variations may especially occur with a mass lower than 0.1 kg and a specimen
thickness of less than 1 mm if the test material is excited to resonance or sympathetic oscillations.
Otherwise, such test materials must be fixed to a solid base, e.g. using a viscous paste. The same
applies to the hardness test blocks.

8.2.2 Rebound method

With smaller and less heavy test objects, the impact effect of the impact device may cause vibrations
which could produce distorted measurement results.

- Test objects weighing less than 2 kg must in any case be fixed to the support using couplant so
that there are no any vibrations.

- Test objects weighing between 2 kg and 5 kg must be placed on a large metal support (e. g. a
table) in such a way that they are not moved or caused to vibrate by the impact.

by using the Up and Down keys. Then press SEL and choose the material.
During the measurement you can select other hardness scale. The displayed measurement reading
will be converted according with the new hardness scale if it is calibrated.

NOTE! Calibration of UCI probe is carried out by the direct method, so the conversion is carried out
on the basis of pre-calibration, and does not correspond to any standard.

Install the probe puck on the sample surface, keeping it in the tough skirt as shown in Figure 3a. By
clicking on the skirt thrust both hands to bring the diamond tip of the probe perpendicularly to the
sample surface to the touch (Figure 3b). Slowly (in about 0.5 seconds) by pressing with a force of
(5 or 1 kg depending on probe type) thrust skirt, push the diamond tip into the metal surface,
preventing swinging (Figure 3c). After the beep, remove the probe from the tested object.
