key will display measurement/position
information in inches, fractions or millimeters . With each key press, the
DRO will cycle through decimal inches, fractions (16ths, 32nds, 64ths) and
millimeters.
When the DRO is in 1/16 or 1/32 inch fraction mode, a series of “bars” in the
upper right corner of the LCD, each
representing 1/64th of an inch, may
appear. (ie. When in 1/16 inch mode and three bars are showing, the
measurement displayed is rounded down to the closest 1/16 inch and each
illuminated bar indicates an additional 1/64 of an inch of additional
measurement.) For better resolution, switch to 1/32 or 1/64 mode. For the
best resolution switch to a decimal mode.
