3. Check the value of the Gain displayed at the top of the signal intensity
screen. In the straight-through position, the gain should be either 1 or 2.
Otherwise, the system is not aligned properly or the lamp needs to be
replaced and/or aligned. For your specific M-2000 intensity distribution
of all channels please refer to the system test report. A hard copy is
shipped with each system and a soft copy is included on the backup CD.
4. If part of the UV-VIS signal, optional NIR, or both is “Overloading” as
shown in Figure 4-22, the iris(es) or filter position on the Receiver unit
may need to be closed down until the signal is no longer “Overloaded” as
shown in Figure 4-21. If the system is equipped with the Source ND filter
wheel, this can also be adjusted to avoid the overload (see Neutral
Density Filter Wheel section, page 16).
