Connecting an Optional Pitot Probe or Airflow (straight
pitot) Probe
When connected to a pitot probe, air velocity or air volume can be
measured. A pitot probe can be connected to the “+” and “-”
pressure ports on the Model TA465-P using two pieces of tubing
of equal length. The total pressure port of the pitot probe
connects to the “+” port on the meter, and the static pressure port
of the pitot probe connects to the “-” port on the meter.
For information on how to perform a duct traverse, refer to
Application Note AF-106 .

The pitot velocity needs a valid temperature to perform the
standard or actual velocity correction. This is accomplished
in the “Actual/Std Setup” menu. If no probe capable of
measuring temperature (plug in probe or thermocouple) is
connected, the
“Temp Source” must be set to “Entered”.
The duct air temperature must then be manually inputted by
the user using the “Entered Temp” setting. If the “Temp
Source” is set to Probe or Thermocouple 1 or 2, and no
probe is connected, dashes (------) will appear on the
display.
For more information on entering the temperature manually,
refer to the
Actual/Standard Setup section of this manual.
