4.8.7. LAMP CALIBRATION
120
An important factor in accurately determining SO
light available to transform the SO
compensates for variations in the intensity of the available UV light by adjusting the SO
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, access the Signal
I/O from the DIAG Menu (refer to Figure 4-17), then press:
