3. Let the instrument stabilize by allowing it to run for one hour.
4. Adjust the UV Lamp. (See Section 10.3.2.1 of this addendum)
5. Perform a LAMP CALIBRATION procedure (see Section 6.9.7 of the T100 Manual).
6. Locate the Preamp board (see Figure 3-4 of this addendum).
7. Locate the Following Components On the Preamp board (see Figure 10-5 of this addendum):
