Measurement Wizard - Proceq Equotip 550 Operating Instructions Manual

6.1

Measurement Wizard

This particular wizard helps define the best measurement principle e.g.
impact device to fit the application, simply based on sample geometries
and surface conditions. To start, some basic information must be provid-
ed to define the test piece. When information is evaluated by the device
a series of recommendations are displayed in order of their relevance to
the application in question.
After the initial process is complete, the device recommends the appro-
priate probe, scope of application and preparation information. Settings
will then be adopted and the intelligent measurement process begins.
NOTE! Please verify that correct series number, impact direc-
tion, material group, scales and limits are defined as well as
sub file and folder name.
6.2 Device Verification
During the verification process, the user will be guided through the en-
tire procedure. At the end of the procedure the instrument is considered
verified and the data is stored in the device memory. Verification data is
also stored as the verification is performed, therefore any discrepancies
occurring over time will be noticeable.
NOTE! This wizard can also be started from the menu Sys-
tem  Probes.
NOTE! A Proceq reference test block is required to complete
this wizard successfully.

6.3 Impact Direction Calibration (Leeb only)
Each Leeb impact device requires a calibration in order to automatically
compensate for impact direction. This is easily achieved using this wizard.
NOTE! All impact devices are already factory calibrated when
shipped, however based on the usage and application it is
recommended to recalibrate the impact direction prior to
verification process chapter "6.2 Device Verification". If this
process is not completed currently inaccurate data may be
obtained.
NOTE! This wizard can also be started from the menu Sys-
tem  Probes.
6.4 Conversion Curve Creation
When default conversions are not suitable for the material being tested,
it is recommended to create a customized conversion/correlation. This
wizard guides the user through the complete process in a simple man-
ner and provides all the necessary information on comparative measure-
ments.
This creates a brand new conversion curve which is used for any future
measurements on the material in question.
6.4.1 Minimizing Conversion Errors
Conversion errors will not normally exceed ±2 HR for Rockwell scales
and ±10 % for Brinell and Vickers provided the material group is se-
lected correctly. In most cases, the conversion error is significantly lower.
If higher accuracy is required or if the alloy under test is not covered by
one of the standard conversions, the Equotip 550 provides a variety of
methods to define material-specific conversions.
