STEP TWO: Set the expected SO
The SO
span concentration
2
values automatically default
to 450.0 Conc.
To change this value to the
actual concentration of the
span gas, enter the number
by pressing each digit until
the expected value appears.
The span gas concentration
should always be 90% of the
selected reporting range
EXAMPLE
Reporting range = 800 ppb
Span gas conc.= 720 ppb

This sequence causes the
analyzer to prompt for the

EXIT ignores the new setting
and returns to the previous

ENTR accepts the new setting
and returns to the
