8.4.12 Averaging test
The influence of averaging
shall not exceed 7 % of the in-
strument reading.
This is in complete compliance with
the performance criteria stipulated in
Standard DIN EN 14626.
yes 99
8.4.13 Difference sam-
ple/calibration port
The difference in response of
the analyser to feeding through
the sample or cali
shall not exceed 1 %.
This is in complete compliance with
the performance criteria stipu
Standard DIN EN 14626.
yes 102
8.5.4 Long-term drift
The long-term drift at zero shall
not exceed 0.5 µmol/mol (i.e.
0.58 mg/m³).
The long-term drift at span lev-
el shall not exceed 5 %
certification range (i.e. 4.
µmol/mol
in a measuring range
of 0 to 86 µmol/mol).
The maximum long term drift at zero
Dl
,z
is -0.23
-0.47
µmol/mol for system 2. The
maximum long term drift at span point
Dl
,s
is 0.64
-0.9 % for system 2.
yes 104
8.5.6 Period of unattend-
ed operation
The maintenance interval shall
be at least 2 weeks.
The maintenance interval is subject to
the necessary maintenance tasks and
is 4 weeks.
yes 109
8.5.5 Reproducibility
standard deviation
for CO under field
conditions
The reproducibility standard
deviation under field condi
shall not exceed 5 % of the av-
erage value over a pe
three months.
The reproducibility standard deviation
for CO was 3.45 % of the average
over a period of 3 months in the field.
Thus, the requirements of Standard
DIN EN 14626 are met.
yes 107
8.5.7 Period of availability
of the analyser
The availability of the measur-
ing system shall be at least
90 %.
The availability is 100 %. This com-
plies with the requirements of Stand-
ard DIN EN 14626.
