humidity-interference calibration data in this filter bank was
updated.
e. Humidity gain factor: if a number appears here this means
that this filter bank contains calibration data obtained during
the humidity-interference calibration of filter “A”.
f.
If the following three conditions are found in any filter bank:
·
Gas name: if the name which appears here is the same
as the name of the gas you intend to measure with filter
“A”;
·
Span Calibration performed: if a date appears here;
and
·
Conversion factor: a number appears here;
Then this filter has been properly span calibrated with the
named gas. The filter bank containing this calibration data
is the filter bank, which has to be made active when filter
“A” is to measure this named gas.
g.
However, if the Gas name: is given as “Gas UA number”
then the filter has only been checked to see that it is
functioning correctly, it has not been span calibrated to
measure the gas you wish to measure.
2. Under the heading GENERAL INFORMATION FOR WATER
FILTER – ACTIVE CALIBRATION DATA : check the following
information:
a.
Zero-point Calibration performed: if a date appears here
this is the last time the water-vapour filter was zero-point
calibrated.
b.
Concentration offset factor: if a number appears here
this means that the water-vapour filter has been zero-point
calibrated.
c.
Span Calibration performed: if a date (year-month-
day) appears here, this is the last time span calibration of
the water-vapour filter was performed.
d.
Conversion Factor: if a number appears here this means
that the water-vapour filter has been span calibrated.
When the water-vapour filter has been zero-point calibrated and
span calibrated it is able to measure the absolute concentration of
water vapour in any gas sample in the analysis cell of the Monitor,
and it requires no further calibration.
