2. Set the expected O3 span gas concentration:
SAMPLE RANGE = 500.0 PPB O3 =
< TST TST > CAL SETUP
M-P CAL RANGE = 500.0 PPB O3 =
< TST TST > ZERO CONC EXIT
M-P CAL 03 SPAN CONC:
400.0 Conc
0 0
4 0 0 .0 ENTR EXIT
M-P CAL RANGE = 500.0 PPB O3 =
SPAN EXIT
This sequence causes the
analyzer to prompt for the
expected O3 span
concentration.
The O
3
span concentration value automatically
defaults to
400.0 Conc
.
Make sure that you input the ACTUAL
concentration value of the SPAN Gas.
To change this value to meet the actual
concentration of the SPAN Gas, enter the
number sequence by pressing the key under
each digit until the expected value is set.
EXIT ignores
the new setting and returns to the previous
menu.
ENTR accepts the new setting and returns to the
previous menu.
NOTE
For this Initial Calibration it is important to independently verify
the PRECISE O
3
Concentration Value of the SPAN gas.
