Once the analyzer is suitably located, all components serviced and
installed, and sample and electrical connections made, the instrument is
ready for operation.
When power is turned on, power is applied to the cell compartment
heater. The cell operates without applied power, but its output will vary
with changes in ambient temperature.
When the analyzer is initially put into operation, the air in the lines and
sample passages will drive the output indication to the top of the scale. The
time required to sweep out this residual air may be several hours before an
on-scale indication is reached. During this time the cell compartment is
heating and reaching its controlled temperature.
The analyzer is calibrated by adding a known amount of oxygen into
the analyzer by means of a calibrated span gas. The sensitivity of the ana-
lyzer is adjusted until the change indicated by the analyzer is equal to the
amount of oxygen known to be present in the span gas. The span gas must
be composed of the same elements as the specified sample gas if the
analyzer's calibrated flowmeter is to be used. TBE/AI recommends that the
oxygen content of the span gas be between 70–90% of full scale on the
range of interest.
