Page 4: Introduction
Manual Introduction Thank you for purchasing a PCE-2500 hardness tester from PCE Instruments. Forewords 1.1.1 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. -
Page 5: Notation Of Leeb's Hardness
Manual Notation of Leeb’s Hardness 1.1.3 When measuring the hardness of a sample material using the traditional static hardness testing method, a change of applied pressure will result in a change in the hardness reading. This will also happen during a Leeb’s Hardness test when one changes the impact device. -
Page 6: Features And Application
Manual Features and Application Introduction This instrument is an advanced state-of-the-art palm sized metal hardness tester with many new features which are light weight, easy operation, integrated design, high contrast display, low operating temperature, auto compensating for impact direction and etc. It can be widely used for measuring hardness of almost all ferrous and non-ferrous metal materials for scale of Leeb hardness, Rockwell C, B &A, Brinell, Vickers, Shore and Strength. -

Page 8: Preparation Before Measuring
Manual Preparation before Measuring Requirements for the sample 6.1.1 The surface temperature of the sample should be less than 120 °C. 6.1.2 The sample 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 2 µm. -
Page 9: Supporting The Samples During Testing
Manual Supporting the Samples during testing When measuring hardness with this tester, the following has to be noticed: Despite the low mass of the impact body and low impact energy, a relatively large impact force of short duration is generated when the impact body hits the measuring surface. -

Page 14: Impact Device
Manual 7.6.1 Impact Device There are two kinds of impact device can be selected. Impact device D is for normal application and DL is for some specific situation, such as narrow step or deep blind hole. When you select impact device DL, you need to change impact body D to DL. -

Page 18: Changing Impact Body
Manual Changing impact body This tester has a very unique feature, which impact device can convert between D and DL simply by changing impact body. This two-in-one probe is equivalent to two individual probes. With this optional accessory, you can take measurement at very narrow surface such as slot bottom, gear tooth that probe D cannot match. -
Page 19: Take Measurement
Manual Take measurement Place the tester onto the surface of object to be measured by the support ring. Please note: the proper way of holding is important for obtaining better readings. Attention: the tester must be placed against object surface firmly and perpendicularly. A slight gap between support ring of tester and surface of object will lead inaccurate reading. -
Page 20: Disposal
Manual 11 Disposal For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose. In order to comply with the EU directive 2012/19/EU we take our devices back.
