Tap Stray light test.
The result is displayed as Pass or Fail:
Pass: the UV Monitor is working as it should.
•
Fail: clean, reassemble and secure the UV flow cell and the connected
•
tubing. Make sure that the detector is not exposed to e.g., direct sunlight.
If the test fails again, replace the flow cell and then possibly the UV
Monitor, or contact a GE Service Engineer.
Flush the system with demineralized water so that the Abs value returns
close to zero.
