Enter the permitted tolerance on the
span concentration calculated by the
analyzer.
This is expressed as a percentage of
the span concentration. For
example, a Validation Pass Level of
5%, with a 21%O2 validation test
gas bottle would correspond to
successful validation if the reported
validation readings would be
between 20%O2 and 22%O2.

cell.
Standard lengths for Servomex
supplied in-line validation cells are
either 0.1m or 0.2m.
You cannot enter a number <0.1m
12 Enter the permitted stability of your
process concentration expressed as
percentage standard deviation of the
span concentration.
At all stages of the validation
process, the analyzer will wait for the
measurement concentration to
achieve this stability before
proceeding refer to section 6.12.3 for
more details of the process stability
measurement.
