Operating manual – dynamic pressure anemometer TA400
Measuring the differential pressure
In the measuring mode for differential pressure measurements
the differential pressure of a zone1 can be determined with
regard to a reference environment (zone2 / equipment
location).
The differential pressure can be indicated in 5 different units:
• PSI
• mbar
• inH
2
O
• mmH
2
O
• Pa
1. Connect the white tube to the +input(4).
ð The -input(15) will not be connected to a tube.

2. Press the P/V/Fbutton(11) until PRESS appears in the
measuring mode display(35).
3. Press the Unit
button(13) to select the desired unit for
the measurement.
ð The selected unit appears in the pressure unit
display(33).
4. Press the HOLD/ZERO button(9) for approx. 2s to carry out
a zero point reset.
5. Position the free end of the tube in the area (zone1) the
differential pressure of which is to be determined with
regard to the measuring device (zone2).
ð The measured differential pressure value will be
indicated in the measurement value display(19).
ð A positive measured value indicates that the pressure in
zone1 is higher than in zone2.
ð A negative measured value indicates that the pressure
in zone1 is lower than in zone2.
ð The measured value 0 indicates an identical pressure in
both zones.
Note:
Additionally, you can connect the black tube to the -input(15).
Bear in mind that in that case the reference environment zone2
is equivalent to the end of the black tube, not the device
location.
