4.6.6. LAMP CALIBRATION

An important factor in accurately determining H2S concentration, once the H2S is

converted to SO2, is the amount of UV light available to transform the SO2 into SO2* (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 H2S 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:
