problem and this error message appears.
To troubleshoot:
1. Locate the source of the leak by visually inspecting the tubing, fittings,
and flow cell.
2. Tighten fittings (or replace tubing and fittings) as required (see
Section
3. If the flow cell continues to leak after resuming operation, replace the cell
(see
Section
4. After fixing the leak, use a cloth or tissue to wipe up all liquid from the
drip tray and dry the leak sensor.
Make sure that you do not bend or damage the sensor.
5. Clear the
Low lamp intensity.
This error occurs when the intensity of the 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 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
noise sensitive and the limit may need to be set higher than the default.
2. Replace the deuterium lamp (P/N 066347) (see
lamp (P/N 066348) (see
3. If the error appears again, contact Thermo Fisher Scientific for assistance.
The detector optics may be defective.
