2.3 Advanced Setup
The following sections describe the procedures for completing the configuration of your HygroPro transmitter.
2.3.1 Setting Up the Pressure/Temperature Displays
The following steps set the displayed pressure and temperature values to Live (changing with the current
measurements) or Constant (remaining the same, regardless of the current measurements). If the Constant option
is selected, the desired numerical value must be set. Please note there is no indication on the display if either value is
set to Live or Constant.
In the Main menu (press Escape) navigate to Constants and press
Enter.
To set the pressure/temperature display, use the arrow keys to select
Pressure/Temperature. Press Enter.
Use the arrow keys to select either Live or Constant Pressure or
Temperature and press Enter. For example, constant pressure of
70 bar could be selected if the desired measurement output is the
Equivalent DP @ 70 bar.
CAUTION!
Please be careful to select sample pressure and
temperature settings to the best option for the chosen
hygrometry measurement. Certain absolute
measurements like mg/m
3
, g/m
3
and PPMv do not
depend on sample temperature and/or pressure, while
others such as Dew Point, Equivalent DP, and lbs/MMSCF
require an accurate live sample pressure and
temperature reading.
If you selected Constant Pressure, please note the default units, which
can be changed by navigating to the Measurements menu as
described above.
Use the arrow keys to enter the desired pressure value and press Enter.
The screen will be updated to show the new pressure value.
Note: The default value for Pressure is Constant (0.00 PSIg) as the
pressure sensor is optional.
Note: As shown in the Menu map in Figure 16, the default value for
Temperature is Live as all HygroRTE probes include a
temperature sensor.
Use the same procedure to set the temperature mode, and if
Constant Temperature is selected, to enter the constant temperature
value.
