Calibration overview
Calibration is an essential operation that completes readhead set-up, with the optimum incremental and reference mark signal settings stored in the readhead's non-volatile memory.
This section is an overview of the calibration procedure for an ATOM system. For more detailed information on calibrating the system see
Manually exit calibration routine.
The readhead set-up LED will stop flashing Blue.
ATOM linear installation guide
Systems are shipped with AGC switched off.
When AGC is switched off the readhead set-up LED will be Green, Orange or Red.
Align the readhead to maximise signal strength over the full length of travel.
Initiate incremental signal calibration routine.
The readhead set-up LED will be single flashing Blue.
Move the readhead along the axis at slow speed (< 100 mm / s).
The readhead set-up LED will start double flashing Blue.
No reference mark
The system is now calibrated and ready for use.
NOTE: If calibration fails (readhead set-up LED continues flashing Blue), restore factory defaults,

29, and repeat the installation and calibration routine.
Ensure AGC is switched off.
The readhead set-up LED will be Green.
Move the readhead back and forth over the chosen reference mark
AGC can now be switched on if required.
