6.9.7. Lamp Calibration
An important factor in accurately determining H
2
S concentration, once the H
2
S is converter to SO
2,
is the amount of UV light available to transform the SO
2
into SO
2
* (see Section 10.1.1 and
10.1.2). The model 6200E compensates for variations in the intensity of the available UV light by
adjusting the H
2
S concentration calculation using a ratio (LAMP RATIO)that results from dividing
the current UV lamp (UV LAMP) intensity by a value stored in the CPU’s memory (LAMP_CAL).
Both LAMP Ration and UV Lamp are test functions viewable from the instruments front panel.
To cause the analyzer to measure and record a value for LAMP_CAL, press.
