SETUP
The SO
2
span
concentration values
automatically default to
400.0 Conc.
To change this value to
the actual concentration of
the span gas, enter the
number by pressing the
key under each digit until
the expected value
appears.
EXIT ignores the new setting
and returns to the previous
display.
ENTR accepts the new setting
and returns to the
previous display..
NOTE
For this Initial Calibration it is important to independently verify the PRECISE CO
2
Concentration Value of the SPAN gas.
If the source of the Span Gas is from a Calibrated Bottle, use the exact concentration
value printed on the bottle.
