The table above shows the list of units that can be set.
This time, we selected Millimeters as an example.
When you connect the panel, it displays “Millimeters,” confirming that it is set up correctly.
You can also enter texts to set or specify units.
The image above shows an example of combining “Millimeters” with the letters ABCD.
When the characters corresponding to a unit are connected, it indicates that the unit is set or specified.
On the other hand, if you enter a text that does not match, it will display as None, indicating that no data exists.
