Figure 9.18 Vis Typical Energy Level at 546nm
NOTE: In the above, if the sample energy is at maximum (>6000000), then there is no energy
reaching the Detector board. Check the light path for blockage or misalignment. If these
are not a problem, then replace the Detector board.
When the voltage gain is increased by an increment of 1, the gain steps and gain ratios for the Vis
(sample detector) and UV (sample and reference detectors) models should be:
