Making an adjustment to the temperature overrides EBTRON’s NIST traceable temperature
calibration.
5.3.7. Average Relative Humidity of the RH Sensors [AVG RH]
The average, non-integrated relative humidity of all properly functioning humidity sensors as %RH.
[Menu path: SETTINGS ↓ DIAGNOSTICS > DEV INFO ↓ LOC DIAG >↓ AVG RH]
Applies to: GTx116e-P/H models only (i.e. models with the /H humidity sensor option).
5.3.8. Average Relative Humidity Offset Adjustment [RH OFF]
A user entered relative humidity offset in %RH.
[Menu path: SETTINGS ↓ DIAGNOSTICS > DEV INFO ↓ LOC DIAG >↓ RH OFF]
Applies to: All models.
Use the ↑ and ↓ pushbuttons to enter a user defined offset. Press the ENT pushbutton to accept the offset or
the ESC pushbutton to keep the previous value.
The relative humidity output of the EBTRON device is velocity-weighted and more accurate than the
simple arithmetic average obtained by a field relative humidity measurement or traverse. A field
temperature measurement will not match the velocity-weighted output shown on the display. The
arithmetic average of the relative humidity sensor(s) is indicated by AVG RH in 5.3.7. If an
adjustment is made to a field measurement, it should be to AVG RH and not the displayed or output
relative humidity of the device.
Making an adjustment to either the temperature or the RH sensor modifies the enthalpy and dewpoint
calculations.
5.3.9. Velocity of each Sensor Node [NODE VELOCITY]
The running average velocity of each sensor node in FPM [m/s]. The running average integration is set to 30
and cannot be modified.
[Menu path: SETTINGS ↓ DIAGNOSTICS > DEV INFO ↓ LOC DIAG >↓ NODE VELOCITY> {sensor node list
1 to n}]
Applies to: All models.
Use the ↑ ↓ pushbuttons to navigate through the sensor nodes.
It is normal for velocity of an individual sensor node to fluctuate. The greater the fluctuation, the
greater the turbulence at the measurement location.
5.3.10. Temperature of each Sensor Node [NODE TEMP]
The non-integrated temperature of each sensor node in °F [°C] without any offset adjustment.
[Menu path: SETTINGS ↓ DIAGNOSTICS > DEV INFO ↓ LOC DIAG >↓ NODE VELOCITY> {sensor node list
1 to n}]
Applies to: All models.
Use the ↑ ↓ pushbuttons to navigate through the sensor nodes.
