Functional Check by the User
The UCI tester is a precision instrument and, with appropriate care, should operate properly for a
long period of time. Nevertheless, it is advisable to carry out the following system checks:
◼
Measuring accuracy and reproducibility check as described in DIN 50159-2 using Hardness
Reference Plates. Only use Hardness Reference Plates that are suitable for UCI hardness
measuring (we exclusively recommend our Yamamoto or Buderus reference plates). For this
purpose, at least 3 measurements (distributed over the entire range of the Hardness
Reference Plates) should be carried out. The permissible deviation of the average value from
the nominal reference plate value may not exceed 4% for testing forces HV5 to HV10; for
HV1, up to 7% is permissible, depending on the range. For the low load range from HV0.1 to
HV0.8 the max. measurement uncertainty amounts up to 9% (
chapter 2.1, Measurement
methods, Page 8
)
◼
The penetration diamond must be checked for damage under the microscope.
If any damage to the probe and/or tester is noticed, the device should be switched off immediately
and returned to our service department for verification. This also applies to excessive measuring
value deviations.
i
NOTE!
We recommend an annual inspection of the system at our service department or at any authorized
NewSonic Sales and Service Partner.
