This sequence causes the
analyzer to prompt for the
expected O
3
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.
