3.3.9. Uni or Bidirectional Measurement [DIRECTION]
Uni or bidirectional measurement applies to the -B probe type only.
[Menu path: SETTINGS >↓ GENERAL >↓ DIRECTION]
Default: BI
Optional Settings: UNI
DIRECTION=BI. The sensor measures airflow or equivalent pressure in both directions. The positive
direction is in the direction of the airflow arrow.
DIRECTION=UNI. The sensor measures airflow or equivalent pressure in the direction of the airflow arrow
only.
3.3.10. Temperature Averaging Method [TEMPMETH]
The method used to determine the average temperature of multiple sensor nodes.
[Menu path: no menu item]
Default: WGT (velocity weighted average)
Optional Settings: None
TEMPMETH=WGT. The velocity weighted average of each sensor node is used.
In a moving airstream, the actual temperature of air with a velocity and temperature profile is not
equal to the arithmetic average of the individual sensor node measurements. The true average
temperature should be weighted by the velocity at each sensor node.
The velocity-weighted temperature is used to calculate velocity-weighted relative humidity and
enthalpy, thus compensating for velocity and temperature profiles and improved relative humidity and
enthalpy measurement.
An averaging temperature probe will not match the weighted temperature output if there is both a
velocity and temperature profile. Use the non-weighted temperature readings provided in the
diagnostics menu to compare temperature readings when verification is required.
3.3.11. Relative Humidity Sensor Configuration [H CONFIG]
The configuration of the relative humidity sensor.
The relative humidity sensor configuration parameter is only visible with Advantage IV GTx116e
remote transmitters that have the humidity sensor option, /H, provided with the -P sensor probe type.
[Menu path: SETTINGS >↓ GENERAL >↓ H CONFIG]
Default: RH (relative humidity)
Optional Settings: ENTH (enthalpy), DPT (dew point)
H CONFIG=RH. The calculated velocity-weighted relative humidity based on the relative humidity sensor and
velocity-weighted temperature.
H CONFIG=ENTH. The calculated velocity-weighted enthalpy based on the relative humidity sensor
dewpoint calculation, velocity-weighted temperature and barometric pressure (see Pb CORR).
H CONFIG=DPT. The calculated dewpoint based on the relative humidity sensor and adjacent sensor node
temperature.
