5.2.4 Oxygen Damping<br />

The oxygen measurement can be damped if there are annoying fluctuations in the process gas. Of course<br />
any damping will slow down the reaction time of the transmitter. The larger the number selected here, the<br />
steadier the measurement will be.<br />
The damped oxygen value is also used in the calculation of all other parameters that are based on the<br />
oxygen value. This figure is also used to damp the fluctuations in the external oxygen input if this is used.<br />
RANGE: “No Damping” to 5 minutes<br />
(5 seconds is set after a COLD-START)<br />

This function allows the operator to automatically suppress spike suppression caused by condensation.<br />
Due to the high levels of moisture in some environments it is not unusual to experience condensation buildup<br />
on the inner and outer sheath of the probe. When this occurs the condensation will often drip back onto<br />
the hot sensing area of the probe causing rapid thermal expansion which causes the probe to read incorrect<br />
levels for some period of time.<br />
This menu allows the operator to set the maximum duration of time that the analyser can automatically<br />
suppress these condensation related spikes.<br />
In normal operation a value of ~2 minutes is acceptable<br />
