READOUT OPERATIONS
DRO 200E
6
On many prints, dimensions are measured
from a datum. By setting the readout’s
absolute display to zero at a well-chosen
edge, you can position the ram based on
dimensions directly from the print.
Setting Absolute Zero (Datum) at the
Current Position
1. Move to desired location.
2. Make sure that the absolute indicator (ABS) is lit.
Press the
A
key if it is not.
3. Press the z key next to the desired axis twice.

key if it is not.
3. Press the z key for the appropriate axis once.
The readout will display the following; “_ _ _ _ _ _ _ 0”.
4. Move slowly until the edge finder touches
the edge of the workpiece. The absolute
position display will automatically be set to
zero at the edge of the workpiece. Refer to
setup to automatically compensate for the
edge finder’s tip diameter.
N ote: You don't have to worry about
overtraveling. The readout
will zero on contact.

finder with your readout, a metallic
surface must be present in order
for the edgefinder to work properly.
