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.
4.1.2 System Setting
See 6.9 for details.
4.1.3 Presetting Testing condition
See 6.5 for details.
User´s Manual HardyTest D700®

Use a calibrated hardness tester, test the standard test block
4.2 Testing Program
Verification of the tester is by using standard test block. The error and repeatability of
displayed value should be within the regulation of Appendix table 2.
Note ：
downward vertically for 5 times, the arithmetical average value compare with the
value of standard test block. If this value exceeds the standard value, could use
the function of software calibration to adjusting.
4.2.1 Start-Up
Insert the plug of the impact device into the socket of impact device on the tester.
Press [
4.2.2 Loading
Pushing the loading-tube downwards until contact is felt. Then allow it to slowly return to the
starting position or using other method locking the impact body.
4.2.3 Localization
Press the impact device supporting ring on the surface of the sample firmly, the impact
direction should be vertical to the testing surface.
4.2.4 Testing
♦ Press the release button on the upside of the impact device to test. The sample

5 Advice
♦ Replacing the impact device must be done during Power off. Otherwise the main
body can not identify the type of the impact device, and it can damage the circuit
board of the main body.
♦ You could not save the current test value if the test times are less than the
presetting times value.
♦ Only type D and type DC of impact device have the function of strength measure
option. You can not modify the [Set hardness orбb ]setting when using other
types of impact device. The [Set hardness orбb ]setting would be set to
[Hardness ] automatically after replacing the impact device whether the setting
is [Hardness ] or not before.
♦ Not all materials could convert to all hardness style value. The hardness style is
reset to HL automatically after changing the material. So select material first
before changing the hardness style.

6.15 Battery Charge
The instrument uses a NI-MH battery pack as its power source. When the battery pack
almost runs out, the battery symbol on the display will glint
soon as possible. Try to drain your battery pack as fully as possible before it is charged for
longest battery service.
♦ The battery switch should be at ‘ON’ condition before charging.
♦ Plug the power adapter into the mains supply power socket and then plug the
charger connector into the power jack of the instrument. If the instrument is in
power off condition, it will turns on automatically after the charger plug is inserted
into the power jack. The battery symbol will alternately shows between
when charging. The more of the dark part indicates the more close to full
capacity.
♦ When the battery is fully charged, the battery symbol on the display will glint
.
♦ Please use the configured AC-DC adapter to charge the battery pack.
Warning: When the battery pack is being charged, printing or paper feeding is
unavailable.

6.16 Battery Replacement
When the battery pack fails to be charged, the user should replace the batteries following the
program below:
♦ Power down the instrument.
♦ Take off the battery compartment cover and take out the battery pack.
♦ Insert the connection plug of the new battery pack into the socket on the circuit
board.
♦ Reset the battery cover.
♦ Turn on the instrument to check.
Warning: Please pay much attention to the polarity of the battery during battery
replacement.
6.17 Connection of Data Transmission Cable
Insert one connection plug of the transmission cable into the USB socket on the right side of
main body, and insert the another plug into the USB port on the back of computer box. Refer

8 Servicing & Maintenance
8.1 Impact Device Servicing
After the impact device has been used for 1000--2000 times, please use the nylon brush
provided to clean the guide tube and impact body. When cleaning the guide tube, unscrew the
support ring first, then take out the impact body, spiral the nylon brush in counter-clock
direction into the bottom of guide tube and take it out for 5 times, and then install the impact
body and support ring again.
♦ Release the impact body after use.
♦ Any lubricant is absolutely prohibited inside the impact device.
8.2 Normal Maintenance Program
When using standard Rockwell hardness block to testing, if all the error is bigger than 2 HRC,
it may be the invalidation of impacted ball top caused by abrasion. Changing the spherical
test tip or impact object should be considered.
When the hardness tester appears some other abnormal phenomena, please do not
dismantle or adjust any fixedly assembled parts. Fill in and present the warranty card to us.
The warranty service can be carried on.
9 Calibration Time
Calibration is needed every 1 year.
10 Notice of Transport and Storage Conditions
♦ Keep it away from vibration, strong magnetic field, corrosive medium, dumpiness
and dust. Storage in ordinary temperature.
♦ With original packing, transport is allowed on the third grade highway.
