1.4 Working Conditions
♦ Working temperature： -10°C～＋50°C;
♦ Storage temperature：-30°C～＋60°C;
♦ Relative humidity: ≤ 90％;
♦ The surrounding environment should avoid of vibration, strong magnetic field,
corrosive medium and heavy dust.
1.5 Safety Instructions
♦ The instrument can only work with the specially designed battery pack and power
adapter (charger) supplied by us. Working with others may result in damage of the
instrument, battery leakage, fire or even explosion.
♦ Do not cast the battery pack into fire and do not short circuit, disassemble or heat
the battery pack, otherwise battery leakage, fire or even explosion may occur.
♦ Do not open the cover of the paper compartment or come into contact with the
heating head of the printer by hand or any part of your body to avoid burns due to
high temperature when the printer is printing.

2.2 Leeb Hardness Testing Principle
The basic principle is: use an impact body of certain weight impacts against the testing
surface under certain test force, then measure the impacting velocity and the rebounding
velocity of the impact body respectively when the spherically test tip is located 1mm above the
testing surface.
The calculation formula is as follows: HL= VB / VA
HL—— Leeb hardness value, VB—— Rebounding velocity of the impact bodyand VA——
Impacting velocity of the impact body

4 Preparation & Testing
4.1 Preparation & Inspection before Testing
4.1.1 Preparation of Sample Surface
Preparation for sample surface should conform to the relative requirement in the Appendix
Table 3.
♦ In the preparation processing for sample surface, the hardness effect of being
heated or cold processing on the surface of sample should be avoided.
♦ Too big roughness of the being measured surface could cause measure error. So,
the surface of the sample to be measured must appear metallic luster, smoothing
and polish, without oil stain.
♦ Support of test sample. Support is no necessary for heavy sample.
Medium-weight parts must be set on the smoothing and stable plane. The sample
must set absolutely equability and without any wobble.
♦ Curved surface: The best testing surface of sample is flat. When the curvature
radius R of the surface to be tested is smaller than 30mm (D, DC, D+15,C, E and
DL type of impact device) and smaller than 50mm (G type of impact device), the
small support ring or the shaped support rings should be chosen.
♦ The sample should have enough thickness, minimum thickness of sample should
conform to Table 3.
♦ For the sample with hardened layer on surface, the depth of hardened layer
should conform to Table 3.
♦ Coupling. Light-weight sample must be firmly coupled with a heavy base plate.
Both coupled surface must be flat and smooth, and there is no redundant coupling
agent existing. The impact direction must be vertical to the coupled surface. When
the sample is a big plate, long rod or bending piece, it can be deformed and
become unstable, even though its weight and thickness is big enough, and
accordingly, the test value may not be accurate. So the sample should be
reinforced or supported at its back.
♦ Magnetism of the sample itself should be avoided.
