Test the formulas prior to use
Always test formulas thoroughly to confirm their correct operation
before using them for inspection.
In this example, the ND 2100G encoders are positioned against the
side and end of a rectangular block. The DRO screen displays a side
dimension of 1.759 mm and an end dimension of 1.255 mm. The
resulting perimeter is calculated to be 6.028 mm, which is correct and
confirms that the formulas are ready to use.
Long formulas
Complex formulas can be entered that require more than a single
formula line. When formulas exceed a single line, the formula is
continued on subsequent lines. It is rare that a single formula cannot
be displayed on a single screen. However, if a formula cannot be
displayed on a single screen, the formula can be scrolled using the UP
or DOWN ARROW cursor keys.
Deleting formula elements
Unwanted formula elements can be deleted from the formula line.
To delete formula elements:
U Use the arrow cursor keys to place the cursor directly to the right of
the formula element to be deleted in the formula line
U Press the CANCEL key. This deletes the function to the immediate
left of the cursor.
U Repeat these steps until all desired formula elements are deleted
