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.
When all installed optical filters (in positions “A” to “E”) have been
zero-point, humidity-interference, span and cross-interference
calibrated (if necessary) then the Monitor is able to perform accurate
measurements.
