Step two is to set the expected NO

span gas concentration:
M-P CAL CONCENTRATION MENU
NOX NO CONV EXIT
SAMPLE A RANGE TO CAL: LOW NOX=X.X
LOW HIGH ENTR
SAMPLE RANGE = 500.0 PPB NOX=X.X
< TST TST > ZERO CONC EXIT
M-P CAL CO SPAN CONC: 400.0 Conc
0 0 4 0 0 .0 ENTR EXIT
The expected NO
2
span concentration value
defaults to 400.0 Conc .
Make sure that you specify the actual
concentration value of the span gas. 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 visble.

ENTR
accepts the expected NO

SAMPLE RANGE = 500.0 PPB NOX=X.X
< TST TST > CAL SETUP
This step only appears if the
analyzer’s reporting range is set
for AUTO range mode.
Select LOW and press ENTR .
Repeat entire procedure for
HIGH range.
