Function/Application
The anemometer is used to measure air flow rates, volumetric flow rates and wind speeds. Integrated sensors constantly register the ambient temperature, relative humidity and calculate the dew point temperature. The USB interface additionally permits realtime logging on a PC.

Safety instructions
- The device must only be used in accordance with its intended purpose and within the scope of the specifications.
- The measuring tools and accessories are not toys. Keep out of reach of children.
- Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
Calibration
The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
Inserting the batteries
Open battery compartment and insert batteries corresponding to installation
symbols. Ensure correct polarity.
ON/OFF
AUTO-Off (20 min.)
Room climate
When switched on, the ambient temperature and relative humidity are
permanently shown on the display. The dew point or wet-bulb temperature can
also be set in place of the ambient temperature. Change between the different
values by pressing and holding the „DP/WP“ button.
You can set the units °C/°F by pressing and holding the „UNIT“ button.
Please refer to the following instructions for use when determining wind speed or volumetric flow rate:
- Position the device parallel to the flow source
- Place the device as close as possible to the flow source
- Use the MAX function to determine the position with the strongest air flow
- Avoid direct sunlight during measurement
Wind speed
After switching on by pressing the „MODE“ button, activate the „VEL“ function.
Press the „UNIT“ button repeatedly to change the units: m/s (metres per
second), km/h (kilometres per hour), mil/h (miles per hour), ft/m (feet per
minute), ft/s (feet per second), knots.
Press the „MAX/MIN“ button to display the highest and/or lowest value during a
measurement. As its name suggests, the „HOLD“ button enables you to hold the
current measured value.
| The „MODE“, „UNIT“ and „MIN/MAX“ functions are deactivated while the „HOLD“
function is activated. These functions are available again after pressing the
„HOLD“ button once more.

Volumetric flow
The outlet area of the flow source must first be defined before determining volumetric flow.
After switching on by pressing the „MODE“ button, activate the function for
measuring volumetric flow until „AREA“ appears on the display. The first
number begins to flash. Use the „5“ (+) and „SET“ (change decimal place)
buttons to enter the determined area. The area can be set both in square
metres (m²) as well as in square feet (ft²). The end of the input is signalled
by a double beep.
Activate the „FLOW“ function by pressing the „MODE“ button. After selecting
the corresponding unit – CMM (cubic metres per minute), CFM (cubic feet per
minute) and CMS (cubic metres per second) – press the „UNIT“ button to
determine the volumetric flow based on the set area.
| The „MODE“, „UNIT“ and „MIN/MAX“ functions are deactivated while the „HOLD“
function is activated. These functions are available again ! after pressing
the „HOLD“ button once more
---|---
MIN/MAX / HOLD
The MAX function is activated by pressing the „MAX/MIN“ button. The measured value currently displayed corresponds to the largest measured value. Press the „MAX/MIN“ button again to activate the MIN function and show the smallest measured value. To deactivate „MAX/MIN“, press the button again until the value is no longer shown on the display.
Press the „HOLD“ button to hold the current measured value on the display.
Press the button again to deactivate this function.
USB transfer
Measured values can be transferred to a PC in realtime via the integrated USB
interface. The values can then be stored and documented using the supplied
software. First install the software and the corresponding drivers from the CD
to the terminal unit. Follow the instructions for the installation routine.
Once you have successfully installed the software, connect the measuring
instrument to the PC and set up a USB connection.
Start the software and activate the USB function by pressing and holding the „USB“ button. The software now shows the measured values both in numerical as well as in graphic form.
For further information on how to use the software, refer to the Help function
that contains a detailed description of the functions.
