    50150. Up to 100 000 readings including hardness, date, time and measuring parameter can be stored to the internal memory of the alphaDUR mini. The memory can be divided into sections for use by different users or projects. Saved series of measurements, including statistics, can be readily displayed or printed.

    THE TEST PROBES 3 The test probes 3.1 Probe selection alphaDUR UCI test probes are available with test loads of 10, 20, 30, 49, and 98 N. This corresponds to HV1, HV2, HV3, HV5 and HV10 (1, 2, 3, 5 and 10 kg). So the optimal load for a particular test task can be chosen.

    5 Measurement The measurement can be started with the menu item Measurement. If a probe is connected to the alphaDUR mini, the measurement window will by shown directly after start-up. The test load of the connected probe will be detected automatically.

  • Page 14: Measuring Parameter

    MEASUREMENT To avoid this effect, the specimen has to be thick enough to allow the os- cillations to attenuate before the diamond is reached. With thin speci- men, the mass of the specimen has an effect. If the mass of the speci- men is high enough, a thickness of 8 mm for flat specimen or 10 mm for round stock is sufficient.

    MEASUREMENT meets the requirement already has been saved, you can use the menu item Measuring parameter/Load (see 6.2.3) to reload them. After power-up, the alphaDUR mini restores the measuring parameter which were last used. 5.3 Measuring procedure To take a measurement, put the probe vertically onto the specimen and press it down steadily as far as it will go.

  • Page 24 MATERIAL CALIBRATION A factory-provided standard calibration for steel is preset in the alphaDUR mini and cannot be deleted. The calibrations can be grouped to sections. So a two-level hierarchy is established to keep things clear if lots of calibrations shall be saved. E.g.
  • Page 25 After the calibration parameter have been set, the calibration can be continued by cursor right ►. Now, the measurements for calibration must be taken. The alphaDUR mini sounds a beep at the end of each measurement. The probe should be lowered evenly and steadily.

  • Page 26: Memory Functions

    Now, the new calibration can be selected in Measuring parameter / Edit / Material. 9 Memory functions The alphaDUR mini can store up to about 100.000 readings. These readings are organized in measurement series (groups). When a new series is created, name for it must be entered. By these names the series can be selected for display and printout.

  • Page 31: The Uci Method

    THE UCI METHOD 12 The UCI method The UCI method (Ultrasonic Contact Impedance) is successfully used in hardness testing since many years. A rod is excited into a longitudinal oscillation. At the tip of the rod, a Vickers diamond is placed. This diamond is pressed to the specimen with a discrete test load.
  • Page 32 THE UCI METHOD The advantages of the UCI method are the ease of automation and the very good reproducibility of the hardness readings. The reproducibility of the measurements is better than with optical methods of hardness testing because the total area of contact (proportional to d ) enters into the measurement and not only the diagonal d or a diameter.
