Optical Brinell Scan System
Model No. PHT-5000
*Laptop not included
In case of measurement by circle, mouse press on one end of the indentation
diameter and drag to the other end. If the indentation shape is elliptical, then
measurement by major-minor axes applies, mouse press on one end of the
indentation major axis and drag to the other end, and then do the same on the
minor axis. Enter the known HB value of the sample at the prompt; the system
should be calibrated and ready for measurement. To re-calibrate the system, it is
necessary to unload the calibration. To do so, select menu Calibration-
>Calibration viewer, enter password if set or click OK to pass, click Unload
button and close the viewer, the system should be at un-calibrated state. Do
calibration as described above. Note: the formula to calculate HB is: HB = 2 X F /
(πX DbX (Db– (Db2– Di2)1/2)), where F is the test force in Kg, Dbis the indenter
ball diameter in mm, and Diis the indentation diameter in mm. To obtain better
accuracy, user may re-calibrate with the average of multiple indentations on the
calibration sample, to do so click on the Re-calibrate with sample average button
in the Settings tab, and enter the HB value of the calibration sample. The re-
calibrated data is activated and saved automatically.
6. Measure: If the camera is still (e.g, after a measurement), push the camera
button, or press the Space key on the keyboard, or click on the Video Preview
button to start camera preview. Move the camera or the sample to make the
indentation appear in the middle of the preview. Make the measurement as
described above.
7. Correct the measurement: If correction of measurement is needed, mouse press
and drag the label circle (in case of Measure by circle) or the four vertices (in case
of Measure by major-minor axes) to align the label with the indentation, and
release. Measurement value and statistics etc will update automatically.
8. Report: Click on the Generate Report button to generate report in Word
format. User may opt not to report the indentation images or the data by checking
the Report Settings on the HB measurement settings dialog.
9. Start a new sample: Click on the New Sample button to clear the measurement
results to start the measurement on a new sample.
