4. Funtzionamendu-argibideak

4.1 Piztu/Itzali

Eduki sakatuta BOTEREA button (labeled with a circle and vertical line) to turn the device on or off. The device will automatically power off after 5 minutes of inactivity to conserve battery life.

4.2 Measuring Wind Velocity and Temperature

1. Ensure the vane sensor is connected.
2. Point the vane sensor into the air flow you wish to measure. The display will show real-time wind velocity and temperature readings.
3. To change wind velocity units (m/s, km/h, ft/min, knots, mph), press the UNITATEA botoia.
4. To switch temperature units between Celsius (°C) and Fahrenheit (°F), press the ° C / ° F botoia.

4.3 Measuring Air Flow (CFM/CMM)

To measure air flow, you need to input the cross-sectional area of the duct or vent.

1. Sakatu VEL/FLOW button to enter CFM/CMM mode.
2. Sakatu UNITATEA button to select between FT² (for CFM) or M² (for CMM).
3. Sakatu SAMPLE AREA button to input the cross-sectional area. Use the arrow keys to adjust the value and AUKERA SARTU baieztatzeko.
4. Once the area is set, the device will display the air volume in CFM or CMM.

4.4 Data Hold, Max/Min/Avg Readings

• Sakatu EUTSI botoia pantailan uneko irakurketa izozteko. Sakatu berriro askatzeko.
• Sakatu MAX/MIN button to cycle through Maximum, Minimum, and Average wind velocity/flow readings.

4.5 Atzeko argia

Sakatu ARGIA button to turn the display backlight on or off. The backlight will automatically turn off after a short period to save battery life.

4.6 Data Recording and PC Connection

The device can record up to 600 groups of wind data. To utilize this feature and connect to a PC for real-time measurement or data download, use the provided USB cable and software (available via CD or download link).

• Sakatu REC to start/stop data recording.
• Sakatu IRAKURRI to view grabatutako datuak.
• Connect the main unit to your PC using the USB cable. Install the provided software to access recorded data and real-time measurements.

5. Mantentzea

• Garbiketa: Garbitu gailua zapi leun eta lehor batekin. Ez erabili garbitzaile edo disolbatzaile urratzailerik.
• Biltegiratzea: Store the anemometer in its carrying case in a dry, cool environment when not in use for extended periods. Remove the battery if storing for a long time to prevent leakage.
• Sentsoreen ordezkapena: The separated wind speed sensor can be replaced if it becomes damaged, extending the service life of the main unit. Contact customer support for replacement parts.

6. Arazoak

• Gailua ez da pizten: Check if the 9V battery is correctly installed and has sufficient charge. Replace if necessary.
• Irakurketa zehaztugabeak: Ensure the vane sensor is clean and free from obstructions. Verify that the correct measurement units and cross-sectional area (for CFM/CMM) are selected.
• Pantaila arazoak: If the display is blank or shows erratic readings, try replacing the battery. Ensure the sensor cable is securely connected.
• Backlight turns off too quickly: This is a design feature to conserve battery. Press the LIGHT button to reactivate the backlight.
• PC konexio arazoak: Ensure the USB cable is properly connected to both the anemometer and the computer. Verify that the software is correctly installed.
