12.7.2.5. ADJUSTING THE UV LAMP (PEAKING THE LAMP)
There are three ways in which ambient conditions can affect the UV Lamp output and therefore the accuracy of the
SO
2
concentration measurement. These are:
Line Voltage Change: UV lamp energy is directly proportional to the line voltage. This can be avoided by
installing adequate AC Line conditioning equipment such as a UPS/surge suppressor.
Lamp Aging - Over a period of months, the UV energy will show a downward trend and can be up to 50% in the
first 90 days, and then a slower rate, until the end of useful life of the lamp. Periodically running the UV lamp
calibration routine (refer to Section 6.9.7) will compensate for this until the lamp output become
s too low to
function at all.
