4.6.6. LAMP CALIBRATION
An important factor in accurately determining H
2
S concentration, once the H
2
S is
converted to SO
2,
is the amount of UV light available to transform the SO
2
into SO
2
* (see
Sections 10.1.1 and 10.1.2). The Model T101 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 Ratio and UV
Lamp are test functions viewable from the instrument’s front panel.
To cause the analyzer to measure and record a value for LAMP_CAL, press:
