stores the expected
CO span concentration value.
This sequence causes the
M300E to prompt for the
expected CO span
concentration.
The O3 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.
NOTE
For this Initial Calibration it is important to independently verify
the PRECISE O

Concentration Value of the SPAN gas.
