of the installed optical filter is the same as the UA number

appearing on the “Calibration Chart” for the optical filter in

position “A”.

Under the headings CALIBRATION DATA IN FILTER

BANK:1; CALIBRATION DATA IN FILTER BANK:2;

CALIBRATION DATA IN FILTER BANK:3; CALIBRATION

DATA IN FILTER BANK:4; and CALIBRATION DATA IN

FILTER BANK:5 check the following information:

b. Zero-point calibration performed: if a date appears here

(year-month-day) this is the last time the zero-point

calibration data in this filter bank was updated.

Concentration offset factor: if a number appears here this

means that this filter bank contains calibration data obtained

during a zero-point calibration of filter “A”.

d. Hum. Interference Calibration performed: if a date

appears here (year-month-day) this is the last time the

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”.

Cross Interference Calibration performed: if a date

appears here (year-month-day) this is the last time cross

interference calibration data in this filter bank was updated.

“Gas name” interference on Filter B, C, D, E: if a number

appears after these headings this means that this filter bank

contains calibration data collected during cross-interference

calibration for this named gas.

h. 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.

However, if the Gas name: is given as “Gas UA number”

then the filter has only been checked to see that it is
