CCD Introduction

Two types of calibration: optical calibration and (manual/automatic) hardness block calibration. The hardness block supports multiple averaging and any number of standard blocks segmented calibration for optimal measurement.
In addition to automatic measurement, there are three types of manual measurement: quadrilateral measurement, diagonal measurement, and four point measurement (the order of selecting the four vertices can be arbitrary).
L supports three types of indentation marking forms: "rectangular box", "red cross", and "circle".
When manually measuring, it has a magnifying glass function to facilitate finding the position of the indentation vertex; The unique keyboard shortcut function allows for quick movement of selected vertices, making measurement operations more efficient.
Provide the pixel distance and physical distance of the indentation diagonal, and calculate the HV/HK value in real-time under the current load.
Support multiple video capture devices, digital cameras with resolutions of 1.3 million and 5 million; The standard configuration is 5 million, which displays indentation videos on the computer and can capture and store images.
L can display and update the current status of the hardness tester in real time, including the current indenter/objective lens, holding time, loading force, etc.
L can manually measure the distance between two points; Multiple sets of distances can also be displayed simultaneously on the video or image.
The software will automatically select the optimal calibration coefficient for different resolutions, objectives, and loads.
All test point information can be identified and marked separately or according to customer needs. The identification information of the test points will be displayed in the test value sequence table and indentation chart for easy query. This function is very important for subsequent analysis and processing.
Referring to hardness conversion standards such as GB, DIN, ISO, ASTM, etc., it can achieve Vickers HV, Knoop HK; Rockwell: HRC, HRA, HRB, HRD, HRE, HRF, HRG, HRK; Surface Rockwell: HR15N, HR30N, HR45N, HR15T, HR30T, HR45T; The mutual conversion between hardness values such as Brinell HBS and Brinell HBW.
When measuring the path sequence of the hardened layer, there are multiple flexible initialization settings modes that automatically save and import the previous path sequence; The measurement path can also be saved as desired for reloading.
The measurement results of the path sequence automatically generate the corresponding hardening layer depth values and hardness change curve graphs.
Multiple analysis modes are available for measuring data; All results can be included in graphic and textual reports. The report content and format can be flexibly set, and Word and Excel documents can be automatically generated.
L can set passwords and management permissions: Ordinary operators can only measure hardness according to the pre-set settings.
Built in tools for converting various standard hardness values, which can automatically convert the measured hardness values according to the table and include them in the result table.
Software available: Chinese or English version.
