MOBILE LEEB HARDNESS TESTER
1 General description
1.1 Features
LCD display of 128×64 matrix is use d.
Converts to all common hardness scales (HV, HB,
HRC, HRB, HRA, HS).
English displaying and menu operating, the
operation is easy and convenient.
With RS232 interface, multiple communication
modes are adopted to meet customized
requirements of various users.
Equipped with 7 types of impact devices which need
not to be recalibrated when changing them, the
system can identify the type of impact device
automatically.
Max 600 groups（impact times: 32～1）of data can
be stored at internal non volatile data storage.
Upper and lower limit of hardness can be pres et; If
the tested value exceeds the limits, alarm will be
sent out automatically to make convenient for the
requirements of batch measurements.
Back light display has been used to make
convenient for the use in poor light.
Test values software calibration function.
Material of “cast steel” is added; HB values can be
read out directly when D/DC impact device is used to
measure “cast steel” work piece.
Printer be separated from main unit and copies of
testing results can be printed as required.
Power is two of AA battery. Continuous working
period: approx. 200 h (no back light on).
Software of PC can be installed according to the
requirements of user, the function will be more
powerful to satisfy the more st rict demands of qualit y
control and management.

4.1 Preparation and Inspection prior to testing
4.1.1 The preparation of work piece surface
The preparation for work piece surface should comply with
the relevant requirements specified in table 3
2.2 Testing principle
Let an impact body whose weight is definite rush into the
surface of sample, the hardness value comes from the rate
of rebound velocity and rush velocity at 1mm distanc e from
testing surface. The calculation formula is following:
Fehler! Textmarke nicht definiert.HL=1000×VB/ VA
In which: HL——Leeb hardness value
VB——Rebounding velocity of the impact body
VA——Impacting velocity of the impact body
Output signal diagram of the impact device is as following.
HK-D-BA-e-1311 6
During the preparation for sample, the affect to surface
hardness of sample caused by overheating, cold
processing and etc. should be avoided as far as possible.
If the surface to be tested is too rough, measuring error will
appear. So the surface of the sam ple must have metallic
luster and the surface must be flat, smooth and have no oil
dirt.
Curved surface: it is better that the testing surface of work
piece is plane. When the curvature radius R of the curved
surface to be tested is less than 30mm (for D, DC, D + 15,
C, E and DL type impact device) and less than 50mm (for
G type impact device), a small support ring or non
conventional support ring should be used.

work piece supporting
—— Support is not necessary for heavy test work piece
—— The work piece with medium weight must be placed
on flat and solid plane, and it must be placed stably without
any shaking.
Enough thickness of work piece is necessary, and the min.
thickness should comply with the specification in table 3.
As for test piece with hardened surfac e layer, the depth of
hardened layer should comply with table 3.
Coupling
——The work piece with lightweight must be firmly coupled
with the support; both coupled surface must be flat,
smooth and the coupling agent should not be too much.
The measuring direction must be vertical to the coupled
surface.
——When the work piece is a large area plat e, long rod or
bending piece, it can be deformed and become unst able
even the weight and the thickness is heavy and the test
value may not be accurate. So i t should be reinforced or
supported at the back of the work piece.
Self magnetism of work piece should be less than 30

Specific procedures for setting, refers to 6.9.
4.1.3 Measuring condition setting of tester
Specific procedures for setting, refers to 6.5.
4.2 Testing
A standard hardness block should be used to check the
tester prior to the testing; and the reading value er ror and
repeatability should not be more than t he specification in
table 5.

which had been calibrated; five measurements
should be carried out in direction of vertical down

Press tightly the support ring of impact device on the
surface of test s ample, the direction of impact should be
vertical with testing surface.
4.2.3 Testing
Press down the release button on the top of the impact
device to make a test. At this point, the test sample, impact
device and the operator are all required to be s table; and
the force direction should comply with the axis of the
impact device.
Five measurements should be carried out per measuring
position of test sample. The divergence of dat a should be
not exceeds ±15HL of mean value.
Distance between any two indentations, or the distance
between any indentation centre and the edge of test
sample should be in accordance with the speci fication of
table 6.
For any special material, a comparative test must be
performed to obtain relevant conversion relation if Leeb
hardness value accurately conversing to other type of
hardness value is required. Procedures are as f ollowing:
tests are made on the same test sample via Leeb
hardness tester which recalibrated well and relevant
hardness meter respectively; for each hardness value, fi ve
points which uniformly distributed around hardness
indentation should be chos en to make tests, and test s for
three (at least) indentations should be made; the mean
value of Leeb hardness and the mean value of relevant
hardness will be act as relevant values respectively to
make a comparative hardness curve. Three groups
corresponding data should be included at least in
comparative curve.

Hardness value will be displayed ahead of HL (the symbol
of Leeb Hardness), and type of impact device will be
displayed back of HL. For example, 700HLD expresses
that the Leeb hardness is 700 by means of the
measurement made by D type impact device.
For other type hardness which changed from Leeb
Hardness value, corresponding hardness symbol should
be added ahead of Leeb hardness symbol. For example,

5 Special prompts
Replacing impact device must be performed under the
condition of turn off, otherwise the impact device type can
not be identified automatically, and even it i s possible to
cause the damage of circuit board of the tester.
In normal conditi ons, the current measured value can be
printed or stored if the 【 Impact times】 value which had
been set is not satisfying. If the printing and storing are
required at this point, 【 Average】 key can be pressed to
finish measurement, then printing can be carried out.
The functions of 【 Auto Save】 , 【 Auto Print】 , and 【 Auto

material should be set firstly when measuring, then
hardness scale should be set.
Note: what is called “conversion” refers to the
corresponding relationship of Leeb Hardness and
other hardness for a certain material, which
established on basis of abundant tests. According to
the conversion relationship, the Leeb hardness value
which measured will be changed into other hardness
scale value automatically via calculating by hard ness
tester.

idle.
One time calibration is enough for each type of impact
device which equipped with a main unit; recalibration is not
necessary after the replacement of impact device later.

8 Maintenance
8.1 Impact device
After using the impact device for 1000-2000 times, use the
nylon brush, optional available, to clean the gui de t ube and
the impact body of the impact device. To clean the guide
tube, unscrew the support ring and then take out the
impact body, spiral the nylon brush in the counter-clock
direction into the guide tube. When the brush reaches the
bottom, draw it out. Repeat this action for 5 times and
mount the impact body and the support ring.
Remember to release the impact body after use.
Any lubricating agent is absolutely banned to use inside
the impact device.
8.2 Standard maintenance procedures
If the error is > 2HRC when using standard Rockwell
hardness block to test, maybe the test tip is disabled.
Changing the test tip or impact body should be considered.
If other abnormal phenomena occur, user should not
disassemble or adjust any part which used f or fixing. You
can return the hardness tester to the service department of
our company.
9. Notice of Transportation and Storage.
The tester should be stored in room temperature, away
from vibration, strong magnetic field, corrosive medium,
dampness and dust.
