1. Forewords 1.1. History The Leeb measuring method was first brought into measurement technology in 1978. It is defined as the quotient of an impact body’s rebound velocity over its impact velocity, multiplied by 1000. Harder materials produce a higher rebound velocity than softer materials. For a specific group of material (e.g. steel, aluminum.
HARTIP 2000 is an innovative portable Leeb hardness tester with our new patent technology which makes HARTIP 2000 a universal impact direction hardness tester. It is no need to set up impact direction when taking measurement by any angle. Therefore, HARTIP 2000 offers a linear accuracy comparing to the angle compensating method.

5. Preparation before Measuring 5.1. Requirements for the sample The surface temperature of sample should be less than 120 C. The samples must feature a metallic smooth, ground surface, in order to eliminate erroneous measurements brought about by coarse grinding or lathe scoring. The roughness of the finished surface should not exceed 2μm.
5.4. Surface of the test sample should not be magnetic. 5.5. For test sample of curving surface with radius of curvature R less than 30mm, a small support ring should be used. 5.6. Supporting the Samples during Testing Type of impact device Classification of samples heavy medium-weight...

Hardness scale is based on the material selected. Not every single material has same conversion. For example, for steel, it has conversions to HRC, HRB, HB, HV, HSD; but for cast iron, only has conversions to HB. Press key consecutively to enter into the menu until “CONV”...
Press key to confirm the setting or press key again to go to first item of menu. When selecting “PON”, an indicator “ ” will appears on LCD which means the communication function is activated for printing or for PC. (Communication with PC needs special software for downloading.) 6.2.
6.3. Data storing and re-reading Set the storage function of tester to be activated. A “S” displays on LCD. At this time, all measuring values will be stored automatically into the memory. after “MEMR” displays and then the last stored During the tester power on, press key value will display.
Connect the tester to the printer with cable. (The printer and cable will be ordered optionally) Press key , a “R” displays on LCD which means the tester is in the re-readable mode, at this time, the last value will display on LCD. ...
At the mode of calibration, you are asked to take 5 measurements on standard test block in total. Among them, 3 measurements are needed to impact downward and 2 measurements are needed to impact upward . Please follow up the indication on LCD to take measurements. During the measurements, you can delete the unsatisfied reading by press key .
