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 4.8.7)
will compensate for this until the lamp output becomes too low to function at all.
Note
As the lamp degrades over time, the software for the CPU compensates for the loss of UV
