- Page 3 Macro Vickers Model No. 900‐398 Tech Support Hardness Tester 1 Introduction Our advanced Macro Vickers hardness tester 900‐398 is a state‐of‐the‐art, precise testing system suitable for hardness analysis of metallic specimens in metallography laboratories or production environments. Designed for the accurate hardness testing of small precision parts, thin materials, case hardened layers and all sorts of steel components. The Phase II 900‐398 is our macro‐vickers hardness tester, covering the load range from 1kg to 50kg, with digital technology. Conforming to ASTM E‐384/92 vickers hardness testers standards, the 900‐398 digital vickers hardness tester will offer unmatched repeatability. A perfect rugged performer suited for any environment, the Phase II vickers hardness testers are offered with a 5 year warranty and free lifetime technical support. The 900‐398 Vickers Hardness Tester is engineered to produce a clear indentation and a more precise measurement. By means of a load cell, closed circuit system for control, the CPU controls testing force to load/dwell/unload, allowing for the highest degree of accuracy. The large LCD shows the measuring methods, the testing force, the indentation length, hardness value, the dwell time of the testing force as well as the number of the measurement on its screen. All information such as diagonal lines length of indentation, hardness values, data statistics and hardness conversions can be displayed on the LCD. The tester can be adapted with a ccd camera for operation and data control via pc. 2 Main Technical Specifications Test forces 9.807N(1 kg), 19.61N(2kg), 24.52N(2.5kg) 29.42N(3kg), 49.03N(5kg), 98.07N(10kg) 196.1N(20kg), 294.2N(30kg), 490.3N(50kg) Test Force Application Method:...

- Page 11 Model No. 900‐398 Tech Support Hardness Tester NOTE: The 900-398 has memory for setting the zero. The only time you need to reset the zero is when the instrument is restarted. Measurement of Diagonal length of indentation: 3.4.12 Observe the indentation in the eyepiece; rotate the handwheel to focus until the image quality becomes clear.
- Page 12 Macro Vickers Model No. 900‐398 Tech Support Hardness Tester The regulation of the hardness tester and the precautions for the operation. 3.5.1 The square pyramidal diamond indenter a.) The diamond indenter and the indenter shaft are important parts of the instrument, and hence it is necessary to take care not to touch the indenter during the operation. b.) In order to assure the precision of the measurement, it is important to keep the indenter clean.
- Page 13 Macro Vickers Model No. 900‐398 Tech Support Hardness Tester 3.5.3 The light source of the micro eyepiece a.) The instrument adopts the cold light source for the lighting. The centrality of the center position of the light source would exert a direct influence on the quality of the image of the indentation. During assemblage of the instrument, the position of the center of the light source is already adjusted, and hence the client does not need to adjust it.
