6.6.1 Measurements
Measurement settings contain all the settings to configure measurements. Here, you
can set the gas standard, gas type, gas humidity and pressure compensation. In ad-
dition, this setting also makes it possible to configure the filter type and the ventilation
parameter pressure source.
Gas standard FlowAnalyser PRO supports various gas standards. The gas
standards are listed under
Gas type The gas that is to be measured must be set on FlowAnalyser

Dynamic Pressure The Dynamic Pressure Compensation setting only affects
Compensation the displayed PChannel value. When the Dynamic Pres-
sure Compensation setting is enabled, a virtual pressure is
calculated, to be found downstream in the device (hence the
measurement is independent of the orientation of the device.).
This replicates the behaviour of the FlowAnalyser PRO. When
the Dynamic Pressure Compensation setting is disabled, the
displayed pressure value is the value which is measured by
the pressure sensor in the flow channel.
Filter type To make the parameters easier to read, the readings are
filtered. Readings are recorded every 1 ms. The following four
options are available:
