Troubleshooting
Raman
RunTime
indicates a
failure during
wavelength
calibration
Stray light from
connected probes is
entering spectrograph
during calibration.
Wavelength calibration is performed with a light
source internal to the Raman Rxn2 base unit. If stray
light from connected probes can enter the
spectrograph, it may interfere with the internal
calibration lamp.
Cover all unused but
connected probe optics
to prevent any stray
light from entering the
spectrograph.
Also, ensure that probes
being used for sampling
are protected from stray
light.

The filter needs
attention.
Clean or replace the filter.
The ambient
temperature is above
35 °C (95 °F).
Lower the ambient temperature to a temperature within the specified ambient
temperature range.
