1. Open the battery compartment at the rear of the device by
sliding the cover down at the arrow mark.
2. Use the battery clip to connect the 9V battery with correct
polarity.
3. Place the battery with the battery clip into the battery
compartment.
4. Slide the cover back onto the battery compartment.
ðThe cover should click into place.
Switching the device on
Note:
Note that moving from a cold area to a warm area can lead to
condensation forming on the device's circuit board. This
physical and unavoidable effect can falsify the measurement. In
this case, the display shows either no measured values or they
are incorrect. Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out a
measurement.
1. Press the power button(10).
ðThe device is switched on.

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
• inH2O
• mmH2O
• Pa

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).
ðThe measured differential pressure value will be
indicated in the measurement value display(19).
ðA positive measured value indicates that the pressure in
zone1 is higher than in zone2.
ðA negative measured value indicates that the pressure
in zone1 is lower than in zone2.
ðThe 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.

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)

ðThe 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)
