5. Configuració

Instal·lació de la bateria:

1. Localitzeu la tapa del compartiment de la bateria a la part posterior de la unitat principal.
2. Open the cover by sliding or unscrewing it (depending on the design).
3. Insert a new 9V (NEDA 1604) battery, ensuring correct polarity (+ and - terminals).
4. Tanqueu bé la tapa del compartiment de la bateria.

Connecting the Vane Probe:

The vane probe is typically connected via a cable to a port on the main unit. Ensure the connector is firmly seated to guarantee accurate readings.

6. Instruccions de funcionament

Encès/apagat:

• Premeu el botó ⑂ button to turn the anemometer ON.
• Manteniu premut el botó ⑂ button for a few seconds to turn the anemometer OFF.
• El dispositiu s'apagarà automàticament després de 20 minuts d'inactivitat per estalviar bateria.

Measuring Wind Speed and Air Temperature:

1. Enceneu el dispositiu.
2. Position the vane probe in the airflow you wish to measure. Ensure the airflow passes through the vane freely.
3. The display will show the current wind speed and air temperature simultaneously.
4. Premeu el botó UNITATS button to cycle through different wind speed units (m/s, km/h, ft/min, mph, knots).

Measuring Air Volume (CFM/CMM):

1. Enceneu el dispositiu.
2. Premeu el botó UNITATS button until CFM or CMM is displayed.
3. Premeu el botó ZONA button. Use the arrow keys (NEXT) to input the cross-sectional area of the duct or opening where you are measuring airflow. Confirm the area setting.
4. Position the vane probe in the airflow. The display will show the calculated air volume.
5. The device can perform up to 20-point average measurements for air volume. Consult the full manual for detailed instructions on multi-point averaging.

Mesura de la temperatura per infrarojos:

1. Point the IR sensor (located at the top of the main unit) towards the surface you want to measure.
2. Manteniu premut el botó ▲ (IR Laser Pointer) button to activate the laser for targeting.
3. The display will show the surface temperature. Release the button to stop measuring.
