Step 3 - Review Quality of calibration:
Calibration Quality Check Procedure
Step Number Action Comment
1. Scroll the TEST
function menu until
the NO
x
SLOPE is
displayed.
The SLOPE value for NO
x
should be 1.0 0.3. If the value is
not in this range, check Section 7.1 or 9. If the SLOPE value is
in the acceptable range the instrument will perform optimally.
2. Scroll the TEST
function menu until
the NO SLOPE is
displayed. The SLOPE value for NO should be 1.0 0.3. If the value is
not in this range, check Section 7.1 or 9. If the SLOPE is in the
acceptable range the instrument will perform optimally.
NOTE:
The NO and NO
x
slopes should be equal within 0.3.
4. Scroll the TEST
function menu until
the NO
x
OFFS is
displayed.
The M9110AH will display the OFFSET parameter for the
NO
x
equation. This number should be near zero. A value of
0.0 50 indicates calibration in the optimal range. If the
OFFSET value is outside this range, check Section 7.1 or 9.1
for procedures to correct the OFFSET value to near zero.
5. Scroll the TEST
function menu until
the NO OFFS is
displayed. The Instrument will now display the NO OFFSET value. It
should also have a value near zero (0.0 50).
Step 4 - The M9110AH is now ready to measure sample gas.
