MEASUREMENT

After switching the

alphaDUR mini

on, the last used combination of

measurement is always parameters active.

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. The hardness value will be determined shortly

before the protective sleeve touches the surface of the specimen. Therefore

vibrations caused by the protective sleeve hitting the surface will not influence

the measurement result. The measurement is completed when you hear the

beep. Within certain boundaries, the lowering speed has no impact on the

measured values. If the test load has been applied too quickly or if the probe is

not raised from the specimen for some time, an error message will be shown.
