automatically default to
400.0 Conc .
To change this value to
the actual concentration of
the span gas, enter the
number by pressing the
button under each digit
until the expected value
appears.
For this Initial Calibration it is important to independently verify the PRECISE CO
If the source of the Span Gas is from a Calibrated Bottle, use the exact concentration value

printed on the bottle.
STEP THREE: Perform the zero/span calibration. Zero and span checks using
the zero/span valve option are similar to that described in Section 5.5, except that
zero air and span gas is supplied to the analyzer through the zero/span valves
rather than through the sample inlet port.
The zero and cal operations are initiated directly and independently with
dedicated buttons (CALZ & CALS).
