4Using the Detector
The Online Plot (Figure 15 on page 56) shows both, the pump pressure and
the detector absorbance signals. Pressing Adjust the signals can be reset to
the offset value and Balance would do a balance on the detector.
13 If both baselines are stable, set the Y-range for the detector signal to
100 mAU.

NOTE
If you start with a new UV-lamp for the first time, the lamp may show initial drift for some
time (burn-in effect).
