4.1 Pŵer Ymlaen/Diffodd

Pwyswch a dal y GRYM 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 UNED botwm.
4. To switch temperature units between Celsius (°C) and Fahrenheit (°F), press the ° C / ° F. botwm.

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. Gwasgwch y FEL/LLIF button to enter CFM/CMM mode.
2. Gwasgwch y UNED button to select between FT² (for CFM) or M² (for CMM).
3. Gwasgwch y SAMPLE AREA button to input the cross-sectional area. Use the arrow keys to adjust the value and OPSIWN NODWCH i gadarnhau.
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

• Gwasgwch y DALWCH botwm i rewi'r darlleniad cyfredol ar yr arddangosfa. Pwyswch eto i'w ryddhau.
• Gwasgwch y MAX/MIN button to cycle through Maximum, Minimum, and Average wind velocity/flow readings.

4.5 Golau cefn

Gwasgwch y GOLAU 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).

• Gwasgwch REC to start/stop data recording.
• Gwasgwch DARLLENWCH i view data a gofnodwyd.

5. cynnal

• Glanhau: Sychwch y ddyfais gyda lliain meddal, sych. Peidiwch â defnyddio glanhawyr sgraffiniol na thoddyddion.
• Storio: 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.
• Amnewid Synhwyrydd: 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. Datrys Problemau

• Nid yw'r ddyfais yn troi ymlaen: Gwiriwch a yw'r batri 9V wedi'i osod yn gywir a bod ganddo ddigon o wefr. Amnewidiwch os oes angen.
• Darlleniadau anghywir: 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.
• Problemau arddangos: 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 connection issues: Ensure the USB cable is properly connected to both the anemometer and the computer. Verify that the software is correctly installed.
