4. Setup

4.1. Battery Installation

The MS6252A requires one 9V 6F22 battery (not included). Follow these steps to install the battery:

1. Locate the battery compartment cover on the back of the device.
2. Slide the cover downwards to open the compartment.
3. Connect a 9V 6F22 battery to the battery connector, ensuring correct polarity.
4. Place the battery into the compartment.
5. Slide the battery compartment cover back into place until it clicks securely.

The device is now ready for use. A low battery indicator will appear on the display when the battery needs replacement.

5. Operating Instructions

5.1. Powering On/Off

• To turn on the device, press the ⓘ (Power) button.
• To turn off the device, press and hold the ⓘ (Power) button for approximately 2 seconds.
• The device features an auto power-off function to conserve battery life. It will automatically shut down after a period of inactivity.

5.2. Wind Speed Measurement

Once powered on, the device will immediately begin measuring wind speed. Hold the anemometer so that the impeller faces directly into the airflow.

• Changing Units: Press the UNIT button to cycle through available wind speed units: m/s (meters per second), ft/m (feet per minute), km/h (kilometers per hour), mile/h (miles per hour), and Knots (nautical miles per hour).
• Data Hold: Press the HOLD button to freeze the current reading on the display. Press it again to release the hold function.
• MAX/MIN Measurement: Press the MAX/MIN button to view the maximum or minimum wind speed recorded since the device was powered on or the function was reset. Press repeatedly to cycle between MAX, MIN, and current reading.

5.3. Air Volume Measurement (CFM/CMM/CMS)

To measure air volume, you must first set the flow area. This feature is crucial for HVAC applications.

1. Setting Flow Area: The device allows setting the flow area (e.g., duct size) to calculate air volume. Refer to the on-screen prompts or specific instructions in the full manual for detailed steps on inputting the area.
2. Selecting Volume Unit: Press the FUNC button to cycle through air volume units: CFM (Cubic Feet per Minute), CMM (Cubic Meters per Minute), and CMS (Cubic Meters per Second).
3. Once the flow area is set and the desired unit is selected, the display will show the calculated air volume based on the measured wind speed.

5.4. Backlight Function

Press the ☀ (Backlight) button to turn the display backlight on or off. This is useful for operating in low-light conditions.

6. Maintenance

6.1. Cleaning

• Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Ensure the impeller is free from dust and debris for accurate readings. Use a soft brush or compressed air if necessary, being careful not to damage the blades.

6.2. Battery Replacement

Replace the 9V battery when the low battery indicator appears on the display. Follow the battery installation steps outlined in Section 4.1.

6.3. Storage

When not in use for extended periods, remove the battery to prevent leakage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. The included black meter bag can be used for protection.
