5. Betjeningsvejledning
The YW-561M is equipped with high-sensitivity probes to ensure accurate and rapid measurements of wind speed and temperature.

Figur 5.1: The YW-561M features high-sensitivity probes for faster and more precise measurements, as demonstrated by its responsiveness to airflow.
The device offers multiple functions to cater to various measurement requirements.

Figur 5.2: The YW-561M's display highlights its multiple functions, including wind speed and temperature measurement, LCD backlight, unit conversion, auto power off, and low power indication.
5.1. Tænd/sluk
- Tryk på Power-knap (
) for at tænde enheden. - Tryk og hold på Power-knap for approximately 2 seconds to turn the device off.
- The device features an auto shut-off function, powering down after 5 minutes of inactivity to conserve battery life.

Figur 5.3: The device automatically powers off after 5 minutes of no operation to extend battery life.
5.2. Valg af enhed
- Tryk på ENHED-knap to cycle through different wind speed units: meters per second (m/s), miles per hour (mph), kilometers per hour (km/h), feet per minute (ft/min), and knots.
- The temperature unit can also be switched between Celsius (°C) and Fahrenheit (°F) using the same button.

Figur 5.4: The device supports five different wind speed units, allowing adaptation to various professional and personal measurement scenarios.
5.3. Measurement Modes (MAX/MIN/AVG)
- Tryk på MAX / MIN knap til view the maximum (MAX), minimum (MIN), or average (AVG) wind speed recorded since the device was powered on or reset.
- Subsequent presses will cycle through MAX, MIN, AVG, and current readings.
5.4. Datahold-funktion
- Tryk på HOLD -knap to freeze the current reading on the display. The 'HOLD' indicator will appear.
- Tryk på HOLD -knap again to release the data hold and resume live measurements.
5.5. Baggrundsbelysning
- Tryk på Baggrundslys knap (often indicated by a light bulb icon, or integrated with the Power button) to turn the LCD backlight on or off. This improves readability in low-light conditions.

Figur 5.5: The backlit screen ensures clear readability of measurements even in dim or dark environments.
5.6. Wind Chill Advisory
- The device displays a "WINDCHILL" advisory on the screen when the ambient temperature drops below 32°F (0°C) and the wind speed exceeds 5 m/s. This feature helps users assess potential cold weather risks.

Figur 5.6: The screen indicates "WINDCHILL" when conditions meet the criteria, alongside the corresponding Beaufort scale level.
5.7. Beaufort Scale
- The device also displays the wind speed according to the Beaufort scale (levels 1-12), providing an intuitive and widely recognized indication of wind conditions.
6. Vedligeholdelse
6.1. Rensning
- Tør enheden af med en blød, tør klud.
- Do not use abrasive cleaners or solvents, as these can damage the casing eller display.
- Ensure the wind impeller is free from dust, dirt, and debris for accurate readings. Gently clean with a soft brush if necessary.
6.2. Opbevaring
- Store the device in a cool, dry place, away from direct sunlight and extreme temperatures, when not in use.
- Remove batteries if storing for extended periods (more than one month) to prevent potential leakage and damage to the device.
