Step 3 - Review the quality of the calibration:
Calibration Quality Check Procedure
Step Number Action Comment
1. Scroll the TEST
function menu until
the SO
2
SLOPE is
displayed.
Typical SLOPE value is 1.0 +/- 0.3. If the value is not in this
range, check Section 7.10 or 9. If the SLOPE value is in the
acceptable range the instrument will perform optimally.
2. Scroll the TEST
function menu until
the SO
2
OFFSET is
displayed.
The 6400A will display the OFFSET parameter for the SO
2
equation. A value between 50mV to 250mV indicates
calibration in the optimal range. If the OFFSET value is
outside this range, check Section 7.10 and 9.
Step 4 - The 6400A is now ready to measure sample gas.
