STEP TWO: Set the expected CO Span Gas concentration:
SAMPLE
< TST TST >
M-P CAL
< TST TST > ZERO
M-P CAL
0
For this Initial Calibration it is important to independently verify the PRECISE CO 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.
STEP THREE: Perform the Zero/Span Calibration. Zero and Span checks using the
Zero/Span Valve option are similar to that described in Section 3.3, except that:
Zero Air and Span Gas is supplied to the analyzer through the zero/span
q
valves rather than through the sample inlet port.
The Zero And Cal operations are initiated directly and independently with
q
dedicated keys (CALZ & CALS).

M300E to prompt for the
expected CO span
concentration.
CO =
EXIT
The CO span concentration value
automatically defaults to 40.0 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.
