Response Coefficient The O
3
Response Coefficient screen is used to change the response of the
ozonator lamp feedback circuit. The larger the number, the more rapid the
response and the higher the noise. Smaller numbers have slower response
times and less noise. Normally, this coefficient should be set to 1.0. Valid
coefficients range from 0.5 to 1.5. The O
3
response coefficient is visible
only when the calibrator is in service mode and if the ozonator option is
installed. For more information on the service mode, see “Service Mode”
earlier in this chapter.
Note This adjustment should only be performed by an instrument service
technician. 

output concentration by adjusting the ozonator lamp intensity. In this
mode, the automatic feedback control of the ozonator is defeated. This is
