UV lamp intensity low.
This error occurs when the intensity of the deuterium lamp is too low,
compared to the reference intensity.
To troubleshoot:
1. If your application is not overly sensitive to noise, reduce the value of the
lamp relative intensity limit (UVRelIntensity.Limit command) in the
Chromeleon 7 Command window or Chromeleon 6.8 Commands dialog
box.
The default limit is 50%. Some applications can be run when the lamp
intensity is as low as 20%. However, other applications are extremely
sensitive to noise and the limit may need to be set higher than the default.
2. Replace the deuterium lamp (P/N 066347) (see
3. If the error appears again, contact Technical Support for Dionex products
