6.2 Wind Speed Measurement
The anemometer can measure wind speed in various units and display maximum, minimum, or current values.
Image: A table detailing the wind velocity measurement ranges, resolution, lowest start point, and accuracy for units including m/s, ft/min, knots, km/h, and mph. Below the table, the anemometer is shown in use, with a hand holding the vane probe to measure airflow.
- Ensure the vane probe is connected to the main unit.
- Point the vane probe directly into the airflow you wish to measure.
- The wind speed will be displayed on the LCD.
- Press the UNIT button to cycle through different units: m/s, km/h, ft/min, knots, mph.
- Press the MAX/MIN button to switch between Maximum, Minimum, and Current (real-time) wind speed readings.
6.3 CFM/CMM Air Flow Measurement
To measure air flow (CFM - Cubic Feet per Minute or CMM - Cubic Meters per Minute), you need to input the area of the duct or vent.
Image: A visual guide on how to measure CFM. It shows the anemometer's display and buttons, with text steps explaining to press 'UNIT' for CFM, then 'AREA' to input duct dimensions, and finally to place the vane probe to measure air velocity, which then calculates and displays the CFM.
- Press the UNIT button repeatedly until "CFM" or "CMM" is displayed.
- Press the AREA key. The display will prompt for area input.
- Use the number keys (0-9) to enter the duct or vent area (e.g., 1 for 1 ft², 2 for 2 ft²).
- Press the ENTER key to confirm the area input.
