Visual check of the Vickers diamond
Periodically check the Vickers diamond under a micro-
scope.
Make sure that the pyramid-shaped diamond is not
damaged.
Checking the measurement accuracy
All UCI probes are calibrated using hardness refer-
ence plates which are certified by the material testing
institute "Materialprüfungsanstalt MPA NRW" for the
corresponding test load (1 kgf, 5 kgf, 10 kgf). Each
hardness reference plate shows natural variations that
have an influence on the measured value deviations
of the corresponding probe from the plate value.
Under well-defined conditions, as is the case with
measurements using the test support MIC 222 on
Krautkrämer hardness plates with acoustic coupling
(thin oil film or ultrasonic couplant ZG between the ref-
erence plate and base), a deviation by
±
3,6 % of the
average from 5 measurements from the plate value is
still permissible (for a max. range of 5 % with refer-
ence to the average).
Individual deviations from the plate value may occur in
freehand measurements depending on the probe
handling. However, they should not go beyond 5 %
from the plate value for 10 measurements.
You should carefully study the handling of the probe
and train yourself in working with the probe by carrying
out measurements on the hardness reference plates
until you obtain stable readings.
Repeat these reference measurements from time to
time and note down the measured average in order to
check the measurement accuracy of your probe.
Any sudden variations indicate a defective diamond or
maladjustment of the probe.
