Numeric keypad

It may happen that a number has to be entered; for example, when entering the memory interval. To enter this function, each key changes its function to a specific numerical key. All four cells must always be completed for each entry. A comma key is also available for volume flow measurement.

Switching the meter on and of

To switch the meter on and off, press and hold the on/off key for at least two seconds.

Automatic power off

If no entry is made within five minutes after switching on, the meter switches itself off. To deactivate this function, hold down the Enter key when switching on and switch on the meter. The display shows “no”. The automatic power off function is now deactivated. Now release all keys to make a measurement. The automatic power off function reactivates whenever the meter is switched off.

Making a measurement

To make a measurement, align the flow sensor with the flow direction. An arrow inside the sensor indicates the orientation in relation to the wind flow. Wait for at least two seconds for the reading to stabilise.

Beaufort scale

The Beaufort scale is always active and shows the current wind force category

Wind force| Designation of the wind force| Designation of the sea state (wind sea)
---|---|---
0| Calm| Completely calm, smooth sea
1| Light air| Calm, rippled sea
2| Light breeze| Mildly agitated sea
3| Gentle breeze| Mildly agitated sea
4| Moderate breeze| Slightly agitated sea
5| Fresh breeze| Moderately agitated sea
6| Strong breeze| Rough sea
7| Near gale| Very rough sea
8| Gale| Moderately high seas
9| Strong gale| High seas
10| Storm| Very high seas
11| Violent storm| Heavy sea
12| Hurricane| Exceptionally heavy sea

Setting the flow unit

To set the unit of the flow velocity, press the “UNIT” key. You can choose between m/s, km/h, ft/min, knots and mps. The default setting is m/s.
Setting the flow unit

Setting the temperature unit

To set the temperature unit displayed, press and release “°C/°F” once. You can choose between °C and °F. The default setting is °C.

Volume flow measurement

For a volume flow measurement, first press the “VEL/FLOW” key to select between velocity and volume flow measurement. This is signalled by “VEL” (speed measurement) and “FLOW” (volume flow measurement) on the display. Depending on the entered area and the measured wind flow, the measured value can also be significantly higher than it is possible to display. In this case,”x100″ or “x10” is displayed next to the measured value. The measured value in the display must then be multiplied by 100 or 10 accordingly

Setting the unit of the volume flow measurement

To select the unit FT³ or m³, press and release the “UNIT” key once.

Hint:
The function also has an effect on the area specification.

Area specification for volume flow measurement

In order to perform a volume flow measurement, it is mandatory to perform an area measurement of the flow. To do this, press the “AREA/SAMPLE” key in volume flow mode. Now enter the area. The unit of measurement m2 or FT2 flashes next to the display. Set the corresponding unit of measurement before entering the area.
volume flow measurement

MAX volume flow measurement

During the volume flow measurement, it is possible to display 2/3 of the maximum volume flow. To do this, press the “ENTER” key. 2/3 MAX” appears on the display. Only 2/3 of the maximum measured value will be displayed. Press the “ENTER” key again to exit the mode.

Lowest, highest and average measured value

For velocity and volume flow measurement, the lowest / highest and the average measured value can be displayed by pressing a key. To use these functions, repeatedly press the “MAX/MIN” key until you have reached your desired function.

Highest measured value

When displaying the highest measured value, only the highest measured value is displayed after activating this function. When “MAX” is displayed, this function is active. When the function is changed, the value expires.

Average reading

When the average reading is displayed, the average of the last 10 seconds is displayed. When “AVG” is displayed, this function is active. When the function is changed, the value expires.

Lowest measured value

When the lowest measured value is displayed, it is only the lowest measured value that is displayed. When “MIN” is displayed, this function is active. When the function is changed, the value expires.

Wind direction

For wind direction measurement, there is an additional gyroscope in the wind speed sensor. The wind direction can be determined via this sensor. To do this, hold the sensor vertically to the air flow. Pay attention to the marking inside the sensor for the flow direction. The display shows the current angle degree and the compass direction as letters:

E: East
W: West
S: South
N: North
ES: Southeast
EN: Northeast
WS: Southwest
WN: Northwest

Calibrating the wind direction
The wind direction should be calibrated when the meter is first put into operation, when it is located in a different region and at regular intervals. To do this, switch on the meter and then align the sensor vertically. Now press and hold the “ENTER” key until the wind direction indicator flashes “- – -“. Now rotate the sensor vertically around its own axis twice for 8 seconds each. Then press the “Enter” key. The calibration is complete.
Calibrating the wind direction

Freezing the measured value

To freeze and hold the currently displayed reading, press and release the “HOLD” key once. The reading is now held. HOLD” appears on the display. Press the “HOLD” key again to resume the measurement.
Freezing the measured value

Recording the measured values

To record individual measured values, the storage interval must be set to “0000” seconds. The storage interval can only be set when the air velocity measuring function “VEL” is set. To do this, press the “SAMPLE” key and now set the storage interval accordingly. Then press the “REC” key whenever you want to save the current measured value. The memory location used is shown on the lower display and the “REC” display flashes once briefly above the display.For continuous recording, set a desired storage interval with the “SAMPLE” key. You can select between 1 … 9999 seconds. Then press the “REC” key once. The lower display briefly shows the storage interval. REC” is shown above the display. This signals that the measured values are being recorded. To interrupt saving, keep the “REC” key pressed. If you press the “REC” key again, recording will be restarted.
Date and time are only saved when recording with the software.

Read out data memory
To read out the data memory on the meter, press and release the “READ” key once. “READ” is now shown above the display. All readings displayed are now those from the memory. Each time you press the “READ” key, the next memory value is displayed. Now press the “AREA/SAMPLE” key and type in the memory location you want to read out. To return to normal measuring mode, keep the “READ” key pressed until “READ” disappears from the display

Delete data
The meter has a memory with 960 measuring points. As soon as the memory is full, “FULL” is shown on the display. To delete the measurement data on the meter, press and hold the “DEL” key for at least two seconds until “CLA” is displayed and “DEL” lights up. All saved data have now been deleted.
Delete data

Hint:
Only the entire memory can be cleared.

Software

To install the software, first go to the page:
