1.3 Nomenclature
CO This is the abbreviation for carbon monoxide.
Span A gas sample of known composition and concentration used to
calibrate/check the upper range of the instrument (carbon monoxide).
Zero Zero calibration uses zero air (CO scrubbed ambient air) to calibrate/check
the lower range of the instrument.
Background Draws air from the background port to compensate for changes in the IR
source and background interferences.
Multipoint Precision Check A procedure to verify the linearity of the instrument.
Calibration The process of adjusting the instrument to ensure that it is measuring the
correct concentration.
Zero Drift The change in the instrument ’s response to zero air over a period of
continuous unadjusted operation.
Automatic Zero The automatic zero performs a zero check at a specified time through a 24-
hour cycle which adjusts the lower limit of the instrument.
Zero Air Is purified air in which the concentration of CO is < 50 ppb with water
vapour of less than 10% RH. The internal CO-CO
2
catalytic converter uses
platinum impregnated alumina beads heated to 90 °C as a conversion agent
to achieve this under ambient conditions.
External Span Source Span gas that is delivered via an external accredited cylinder (e.g.
NATA/NIST).
Sample Air Sample air is defined as the sample before it has entered the Measurement
cell, as distinguished from the exhaust air.
Exhaust Air Exhaust air is the sample air after it has passed through the
reaction/measurement/detection cell and is moving towards being
expelled from the instrument.
ID and OD These are measurements of tubing. ID is the internal diameter of tubing;
OD is the outer diameter.
Multidrop A configuration of multiple instruments connected via the same RS232
cable.
Bootloader A program that checks whether the current firmware is valid and executes
the instrument start-up.
The Bootloader can be entered by pressing the ‘+’
key on the front keypad during the first 1/2 second after power ON and
