Nastavení a montáž

Vybalování

Opatrně vyjměte všechny součásti z obalu. Zkontrolujte, zda jsou všechny níže uvedené položky přítomny a nepoškozené.

• Fluke 925 Anemometer Display Unit
• Vane Sensor with coiled cable
• Návod k použití
• 9V baterie (předinstalovaná nebo dodávaná samostatně)

Instalace baterie

The Fluke 925 Anemometer requires one 9V battery for operation. The battery compartment is typically located on the rear of the display unit.

1. Locate the battery compartment cover on the back of the display unit.
2. Posuňte nebo odepněte kryt pro otevření přihrádky.
3. Vložte 9V baterii a dbejte na správnou polaritu (+ a -) pólů.
4. Bezpečně nasaďte kryt prostoru pro baterie.

Connecting the Vane Sensor

The vane sensor connects to the main display unit via a coiled cable with a connector.

1. Align the connector on the vane sensor cable with the corresponding port on the top of the display unit.
2. Gently push the connector into the port until it clicks or is firmly seated.
3. Ensure the connection is secure to prevent intermittent readings.

Návod k obsluze

Zapnutí/vypnutí

• Chcete-li zařízení zapnout, stiskněte MOC button (usually marked with a circle and a vertical line).
• The device features an auto power-off function after 20 minutes of inactivity to conserve battery life.
• Chcete-li ručně vypnout, stiskněte a podržte tlačítko MOC tlačítko.

Display and Measurement Units

The Fluke 925 features two LCD screens for displaying measurements. You can select various units for wind speed, airflow, and temperature.

• Wind Speed Units: ft/m (feet per minute), m/s (meters per second).
• Airflow Units: CMS (cubic meters per second), CFM (cubic feet per minute).
• Jednotky teploty: °C (Celsius), °F (Fahrenheit).
• Použijte NASTAVENÍ JEDNOTKY button to cycle through and select desired measurement units.

Measuring Wind Speed

1. Ensure the vane sensor is connected.
2. Point the vane sensor directly into the airflow you wish to measure. Ensure the fan blades rotate freely.
3. The wind speed reading will be displayed on the LCD screen.
4. To hold the current reading on the display, press the DRŽET button. Press again to release.

Measuring Airflow (CMS/CFM)

To measure airflow, you typically need to input the area of the duct or opening through which the air is flowing.

1. Stiskněte tlačítko ZAMĚSTNANEC button to select the 'FLOW (area)' mode.
2. Použijte NASTAVENÍ JEDNOTKY button to input the cross-sectional area of the measurement point. Refer to the instruction guide for detailed steps on area input.
3. Position the vane sensor in the airflow. The device will calculate and display the airflow in CMS or CFM.

Measuring Wind Temperature

The Fluke 925 also measures the temperature of the air passing through the vane sensor.

• The temperature reading is typically displayed simultaneously with wind speed or airflow on one of the LCD screens.
• Ensure the device has stabilized in the environment for accurate temperature readings.

Údržba

Čištění

• Wipe the exterior of the display unit and vane sensor with a soft, damp tkanina. Nepoužívejte abrazivní čisticí prostředky nebo rozpouštědla.
• Ensure the vane sensor blades are free from dust, debris, or obstructions that could affect rotation and accuracy. Use a soft brush or compressed air if necessary.

Skladování

• When not in use for extended periods, remove the battery to prevent leakage and damage to the device.
• Store the anemometer in a cool, dry place, away from direct sunlight and extreme temperatures.

Výměna baterie

• Vyměňte 9V baterii, když se na displeji zobrazí indikátor slabé baterie nebo pokud se zařízení nezapne.
• Follow the battery installation steps outlined in the 'Setup and Assembly' section.

Odstraňování problémů

This section provides solutions to common issues you might encounter with your Fluke 925 Anemometer.

• Zařízení se nezapne:
  • Check if the battery is correctly installed with proper polarity.
  • Replace the 9V battery with a fresh one.
• Nepřesné nebo nepravidelné hodnoty:
  • Ensure the vane sensor blades are clean and rotate freely without obstruction.
  • Verify the connection between the vane sensor and the display unit is secure.
  • Ensure the vane sensor is positioned correctly in the airflow, facing directly into the flow.
  • Check for strong electromagnetic interference in the measurement area.
• Display is blank or shows error:
  • Zkontrolujte stav baterie a v případě potřeby ji vyměňte.
  • Zkuste zařízení vypnout a znovu zapnout.
