Scans Won’t Start
You cannot start a scan if the laser is in track mode. Press the
Track
button to switch to scan mode.
Power Display Flashes
In track mode, a flashing power display indicates that the set power is
out of range for the current wavelength.
In scan mode, a flashing power display indicates that the set power is
out of range for at least some wavelengths in the scan range.
Error Codes
The wavelength display will indicate an error code if the controller is
unable to perform its proper functions. The following list describes the
error codes. Switching the laser controller off and then back on can
clear some of these errors. If the error persists, contact New Focus for
assistance.
