Dionex VWD-Related Audit Trail Error Message
VWD-xxxx@USB-xxxxx - Device not found on the USB.
The Warning threshold must be higher than the Limit
threshold.
The Warning threshold must be lower than the Limit
threshold.
Wavelength calibration failed.
You do not have the privilege to change the
performance limits.
You do not have the privilege to change the
qualification intervals.
You do not have the privilege to approve the module's
qualification.
The counter UVRelIntensity (value: x%) has fallen below its
limit (x%). Module should no longer be used. Replace the UV
lamp.
The counter VISRelIntensity (value: x%) has fallen below its
limit (x%). Module should no longer be used. Replace the VIS
lamp.
This error occurs if the relative intensity of the deuterium or tungsten lamp (as
compared to the reference intensity) falls below the value set by the
UVRelIntensity.Limit or VISRelIntensity.Limit parameter.
To troubleshoot:
1. If your application is not overly sensitive to noise, reduce the value of the
lamp relative intensity limit (UVRelIntensity.Limit or
VISRelIntensity.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
tungsten lamp (P/N 066348) (see
