(11) Establishing user programs is convenient and fast:A user program that can be established through translation and rotation.

(12) Edit and modify user programs, intuitive and convenient:You can delete or insert any element, including coordinate systems. You can view the edge finding status of a certain element and change the environment for edge finding measurement. If necessary, an element can be remeasured to change its measurement method and environment.

(13) Manual measurement can be performed during the automatic measurement process of the machine:If a customer wishes to manually measure a certain element or elements instead of the machine automatically measuring them, software can easily achieve this. The software provides a breakpoint setting function, which can be set at the element to be manually measured. When the machine reaches that point, it will automatically stop.

(14) When running the user program, data can be automatically aligned and imported into Excel:

(15) When running the user program, data can be automatically imported into professional SPC software:After setting up the workpiece information in our professional SPC software, once a workpiece is measured, the data will be automatically sent to the SPC software without the need for conversion through TXT files or third-party software. The entire process is automated and does not require human intervention.

(16) When measuring anomalies, intelligent processing can be performed:The software provides out of tolerance pause and measurement failure pause functions, for example, if the workpiece accidentally moves during the measurement process. At this point, the machine will pause and allow the selection for further processing

(17) Auto focus function:Provides precise focusing and fast focusing functions, which can measure height values through focusing. At an optical magnification of 2.0X, the focusing repeatability can reach 0.003mm Or obtain the current point coordinates through autofocus. You can also set whether to perform autofocus when running the user program

(18) Auxiliary dimming:The dimming indicator will indicate to the user when the light intensity is at its best, avoiding measurement errors caused by lighting and improving measurement accuracy and efficiency.

(19) Up to 9 motion control modes:The software provides nine motion control modes for users to easily move the workbench, including: using the operation box to move the workbench, clicking the middle mouse button in the image window, holding the right mouse button in the image window to move, clicking the middle mouse button in the drawing window, selecting to move here in the element list window, clicking the mouse in the motion control window area, clicking the middle mouse button in the scanning window, clicking the middle mouse button in the map window, and entering coordinate values to move.
