Teledyne T100 Manuale Utente

An important factor in accurately determining SO

2

 concentration is the amount of UV 

light available to transform the SO

2

 into SO

2

* (refer to Section 13.1.1).  The T100 

compensates for variations in the intensity of the available UV light by adjusting the SO

2

 

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 5-16), then press:
