7.2.2. Set Expected NO and NO
X
S pan Gas Concentrations
SAMPLE RANGE = 500.0 PPB NOX= X.X
< TST TST > CAL SETUP This sequence causes the
analyzer to prompt for the
expected NO
x
span
concentration.
The NO
X
& NO span concentration
values automatically default to
400.0 Conc.
To change this value to the
concentration of the span gas, enter
the number by pressing the key
under each digit until the value is
set.
EXIT ignores the new setting and
returns to the
CONCENTRATION MENU.
ENTR accepts the new setting and
returns to the
CONCENTRATION MENU..
