Table 7.4 – Sample and Ambient Influence
Sample Pressure
Stability
Output may change up to ±1.6% fsd for a ±1% change in
sample (Gas Analysers) pressure. With optional
empirical sample pressure compensation, effect is
reduced to ±1% fsd or less for a 20% change in sample
pressure for most typical samples.
Sample Temperature
Stability
Output may change up to ±0.3% fsd for gases for a ±1°C
change in sample temperature. With optional empirical
sample temperature compensation, effect is reduced to
±1% fsd or less for a 20°C change in sample
temperature for most typical samples.
Sample Flow Stability Depends on cell volume and vent conditions but for
unheated cells the primary effect is less than ±1% fsd
change in output for flow rate changes of ±10%.
Ambient Temperature
Influence
Less than 1% fsd zero drift due to rate of ambient
temperature change of 25°C/hr (45°F/hr) over a
maximum of 25°C (45°F) change.
