Introduction
ACU-RITE’s DRO 100 readouts provide features for you to obtain increased
efficiency and productivity from your manual machine tools. They are designed
specifically for grinding applications, but they are also particularly useful for X-Y
tables, height gages, and other applications.

Displays
At the top of the display window is a row of indicators. These tell you the current
state of the readout.
In addition to the lighted indicators along the top of the display, the top axis
display will scroll longer messages that will help you step through some of the
procedures.

Power-On Position Recovery
Position-Trac
Certain ACU-RITE encoders, such as the ENC 150, contain closely-spaced
reference marks that enable the display to show the correct position after a power
interruption. The readout will tell you when power has been lost, and will prompt
you to move each axis until a reference mark is located. By traversing the
reference marks once in each axis, you will re-establish the display position
relative to the last known zero. The most you will ever have to move an axis is
about one inch. You must move in the positive count direction. A flashing decimal
point indicates that the last position has not been recalled.
If you use an encoder without Position-Trac, the procedure for recovering your
position is slightly different. Reference marks on these encoders are about 8”
apart. You must find a convenient reference mark and then use the same mark
every time.
1. Move near the desired reference mark.
2. Press and hold the ABS
INCR key until the decimal point starts to flash.
3. Move slowly past the reference mark until the readout recalls its position.
You must move in a positive direction.
