Measuring the air velocity
In the measuring mode for air velocity measurements the
current air velocity is measured with defined standard
conditions (temperature 21.1°C / 70°F, air pressure 14.7psi /
1013mbar).
The air velocity can be indicated in 5 different units:
• metres per second (m/s)
• feet per minute (ft/min)
• kilometres per hour (km/h)
• miles per hour (mph)
• nautical miles per hour in knots (kn)
1. Connect the white tube to the +input(4) of both the device
and the Pitot tube.
2. Connect the black tube to the -input(15) of both the device
and the Pitot tube.

3. Press the HOLD/ZERO button(9) for approx. 2s to reset the
measurement to zero.
4. Press the P/V/Fbutton(11) until VEL appears in the
measuring mode display(35).
5. Press the Unit
button(13) to select the desired unit for
the measurement.
ð The selected unit appears in the velocity unit
display(34).
6. Point the upper end of the Pitot tube towards the air flow. In
doing so, make sure that the Pitot tube is not inclined more
than 10° with regard to the air current.
ð The measured value will be indicated in the
measurement value display(19).
If a negative measured value or the message Error is displayed,
please check the connections at Pitot tube and device for proper
fit and correct polarity.
Measuring the air volume flow
In the measuring mode for air volume flow measurements the
air volume flow is measured with defined standard conditions
(temperature 21.1°C / 70°F, air pressure 14.7psi /
1013mbar).
To achieve a measurement that is as accurate as possible, you
can indicate round and angular current cross-sections incl. the
precise cross-sectional areas.
The air volume flow can be indicated in 2 different units:
• CFM (cubic feet per minute)
• CMM (cubic metres per minute)
1. Connect the white tube to the +input(4) of both the device
and the Pitot tube.
2. Connect the black tube to the -input(15) of both the device
and the Pitot tube.
