Before you begin, ensure the instrument is turned ON and connected to the sensor. Then do the following:
1. Press and hold down the
through the measurement options until the desired FLOW setting appears on the LCD. Choices are:
In - measures incoming (blowing) air flow with a cone.
out - measures outgoing (suction) air flow with a cone.
CUSt - measures air flow without a cone. If you select this option, you must enter the area of the
ventilation register into the DataView Data Logger Control Panel, as explained in step 4 below. The
instrument can then calculate air flow using the speed measurement and ventilation area setting.
2. While continuing to hold down
M3/S (cubic meters per second), M3/H (cubic meters per hour), L/S (liters per second), and CF/M (cubic
feet per minute). When the desired measurement is displayed, release
3. To change temperature units, short-press
4. If you are using an air flow cone: Skip the remainder of this step and proceed with step 5 below.
If you are not using a cone: Connect the instrument to a computer using DataView (§2.2). Select the
instrument in the Data Logger Network and click Instrument -> Configure. Then go to the Anemometer
tab, select Custom, and enter the area of the ventilation register. (Consult the DataView Data Logger
Help system for assistance.) When finished, place the sensor in front of the ventilation register, and go to
step 7 below.
5. Place the air flow measurement cone on the sensor. Depending on the measurement you want to make
(flow in or flow out), place the sensor with the arrow pointing towards the cone (outgoing flow) or away
from it (incoming flow).
6. Place the cone on the ventilation register. The arrow inside the propeller must point in the direction of
the air flow. This will be towards the outside of the cone for a blowing measurement, or towards the inside
of the cone for a suction measurement.

air flow is incoming)
7. The air flow and temperature measurements are displayed on the LCD. (Wait for the measurements to
stabilize before accepting the reading.)
Always hold the sensor by its handle. Keep your fingers away from the sensor propeller.
