Declaration of Conformity Cautions Please carefully read this first 1. Any components of the instrument may not be submerged into water or exposed to rain, which could cause a battery explosion ort he display might be damaged. 2. If the instrument isn’t used for a longer period, it should be stored in dry environment and in its original transport case. The environmental temperature should be within the range of -30°C up to +80°C and relative humidity from (RH) 5% bis 95%. 1. Summary 1.1 Measuring Principle Scope When the test is carried out, an impact body with a tungsten carbide test tip is being impelled by spring force against the surface to be tested, from which it rebounds. Impact and rebound velocities are measured by the following method: a permanent magnet integrated in the impact body passes through a coil and induces an electric voltage during its travel back and forth. These voltages are proportional to the velocities and are processed and displayed as the hardness value “L” at the instrument. Modern electronics with power saving features provide a long operating life. Illustration The big-sized LCD display always shows how the HN-D is configured to test. Variable function keys allow quick changes of common test parameters. No subjective measuring errors are possible, giving highly repeatable results. Internal self diagnostics with error messages assure reliable test results. Readings can be stored automatically in the internal memory or being directly sent to a printer. PC evaluation software enables a data analysis. These conversions to other scales (HRC, HRB, HB, HV, HSD etc.) are programmed into the electronics and can be shown directly on the display as test result. 1.2 Hardness Value „L“ This term, 1978 introduced by Dr. Dietmar Leeb into measuring technology, is the quotient fort he impact body’s rebound and impact velocity, multiplied by 1000. Harder materials produce higher rebound velocities than less harder ones. With reference to a particular material group
