Your controller surely uses a different set of buttons, but this may give you a place to search the manual …
On my KT332N, the jog buttons can run in either Manual or Continuous mode, as shown by the indicator in the lower right of the display:
The big button in the middle of the arrows sets the mode. In
Manual mode, the axes move one step per push, which is probably what you want.
However, setting the exact distance is a major pain. It’s tucked away in Menu → Manual:
Then you apply the arrow keys to each digit, which is why I leave it set to 0.2 mm: I jog into the neighborhood in Continue mode, then sleaze up to the exact spot ±0.1 mm in Manual mode.
You could do that while watching the coordinate display on the main screen, but I’m generally locating something like a Print and Cut target.
