5.2 Attaching the Probe
The retractable hot-wire probe connects to the main unit via a secure connector.
- Align the connector on the probe with the port on the top of the anemometer.
- Gently push and twist the connector until it is securely fastened.
- Extend the telescopic probe to the desired length for measurement.
6. Operating Instructions
6.1 Power On/Off
- Press the POWER button to turn the device on.
- Press and hold the POWER button to turn the device off.
6.2 Basic Wind Speed and Temperature Measurement
Once powered on, the device will automatically begin measuring wind speed and air temperature.
- Position the hot-wire probe in the airflow path. Ensure the sensor head is fully exposed to the air stream.
- Read the wind speed and temperature values displayed on the LCD.
6.3 Selecting Units
To change the units for wind speed or air volume:
- Press the UNIT button to cycle through available wind speed units (m/s, km/h, ft/min, knots, MPH).
- For temperature units, press the °C/°F button to switch between Celsius and Fahrenheit.
- For air volume units (CFM/CMM), ensure you are in air volume mode and press UNIT.
6.4 Air Volume (CFM/CMM) Measurement
To measure air volume, you must first input the duct area.
- Press the MODE button until the display indicates Air Volume measurement (CFM or CMM).
- Press the SET button to enter the duct area input mode.
- Use the MAX/MIN and HOLD buttons (often labeled with up/down arrows) to adjust the area value.
- Press SET again to confirm the area.
- Position the probe in the duct. The device will now display the calculated air volume.

6.5 Measurement Modes (MAX/MIN/Real-time)
The AI-9000F supports different measurement modes for data analysis.
- Press the MAX/MIN button to cycle through:
- MAX: Displays the maximum recorded value since entering this mode.
- MIN: Displays the minimum recorded value since entering this mode.
- Real-time: Displays the current live measurement.
6.6 Data Hold Function
To freeze the current reading on the display:
- Press the HOLD button. The display will show 'HOLD' and the current values will be frozen.
- Press HOLD again to release the data hold and resume live measurements.
7. Maintenance
