Troubleshooting
Cause(s) Solution(s)
The OBR and/or the PC is not
plugged in or turned on (and
the laptop battery is dead, if
applicable).
The OBR and the PC require separate power cords. Plug
in the OBR and/or the PC, or replace dead batteries with
charged ones if using a laptop PC. Instructions for the
PC battery are located in the provided PC manual. Make
sure to turn on the OBR power switch on the front of the
instrument, and the PC according to its instructions.
Blown fuse. Replace the fuse. For instructions, see “Replacing
Fuses” on page 198.
Error Message Solution(s)
This message is displayed if a measurement cannot be
calibrated to the wavelength. This simply means that the
data acquired is accurate in terms of the parameter
displayed on the screen, but the data is shifted in either
direction in terms of wavelength. This problem may
occur once in a while, but the occurrences should be
fairly sparse.
First try to scan again or try scanning over a different
wavelength range to see if the warning indicator is
displayed again.
If the error light persists, it generally means that the laser
(not just the instrument) needs to be recalibrated. First,
run the Self-Diagnostic software and send the resulting
text file to Luna (as described beginning on page 211).
Then you may contact Luna Technologies toll free at
866-LUNAOVA (866-586-2682) or by e-mail at
support@lunatechnologies.com.
The detector has been saturated by a strong reflection,
causing “ghost peaks.” To correct this problem, reduce
the Gain setting in the System Control area by one
level and retry the scan.
