9.6. CALIBRATING THE IZS OPTION O
3
GENERATOR
The following procedure calibrates to output of the O
3
generator that is included in the
IZS calibration valve option ( OPT-50G). This function:
Drives the IZS O
3
Generator to output a series of O
3
levels between zero and full
scale;
Measures the actual O
3
output at each level, and;
Records the generator lamp drive voltage and generator’s O
3
output level in a
lookup table.
Whenever a certain O
3
output level is requested, the instrument’s CPU uses the data in
this table to interpolate the correct drive voltage for the desired O
3
output.
Note Because the instrument waits 5–7 minutes at each step for the O3 level to
stabilize, this calibration operation often takes more than one hour to
complete.
