This section is a quick-start guide to calibrating an ATOM DX encoder system.
More detailed information on calibrating the readhead is on
page 17
of this installation guide.
The optional Advanced Diagnostic Tool ADTi-100 *

and ADT View software
can be used to aid installation and calibration.

Calibrate system
Ensure the readhead set-up LED is flashing Green along the full axis of travel before system calibration.
See pages 12 to 15
for more information on readhead mounting and alignment.
Cycle the power to the readhead to initiate the calibration routine. The LED will single flash Blue.
Move the readhead along the scale at slow speed (<100 mm/s), without passing a reference mark, until the LED starts double flashing Blue.

mark until the LED stops flashing.
The LED will stop flashing.
The system is now calibrated and ready for use. Calibration values, Automatic Gain Control (AGC) and
Automatic Offset Control (AOC) status are stored in readhead non-volatile memory at power down.
NOTE: If calibration fails (LED remains single flashing Blue), restore factory defaults by obscuring the
readhead optical window on power-up
(see page 17)
then repeat the installation and calibration routine.
