12 TROUBLESHOOTING
This section suggests solutions to potential issues that may be encountered when operating the
Cornerstone monochromator. If the tips in this section do not restore the instrument to working condition,
contact Newport to arrange for technical support or repair. Contact information can be found in the
Warranty and Service section of this user’s manual.
12.1 CORRUPTED MEMORY
The monochromator comes with calibration parameters which are stored in a file on the memory
stick shipped with the instrument. If these parameters were corrupted from, possibly, performing
an incorrect field calibration, they will need to be reset. Other possible causes include electrostatic
discharge or other high field radiation near or in contact with the instrument.
The instrument parameters need to be reloaded from the calibration parameter sheet. Use the
utility program and select the first grating. Update the parameters for this grating. Then go to the
second, third, and fourth grating (if equipped) to also update these parameters.
