5. Setup

5.1. Battery Installation

The TA300 anemometer typically uses a 9V block battery. To install or replace the battery:

1. Locate the battery compartment cover on the rear of the device.
2. Open the cover by sliding or unscrewing it (refer to the diagram if available).
3. Insert a new 9V battery, ensuring correct polarity.
4. Close the battery compartment cover securely.

5.2. Attaching the Probe

The telescopic hot-wire probe connects to the main unit via a cable.

1. Carefully insert the probe's connector into the designated port on the main unit.
2. Ensure the connection is firm to prevent signal loss during measurement.

5.3. Initial Power On

Press the power button (⑂) to turn on the device. The display will illuminate, and the device will perform a self-test before showing measurement readings.

6. Operating Instructions

6.1. Extending the Telescopic Probe

The probe can be extended up to 1 meter for reaching measurement points.

1. Gently pull the probe tip to extend it to the desired length.
2. Avoid excessive force to prevent damage.
3. Ensure the probe is fully retracted when not in use to protect the sensor.

6.2. Measurement Modes

The TA300 can measure air velocity, temperature, and volumetric flow.

• Air Velocity (VEL): The primary measurement displayed in m/s, ft/min, km/h, or mph.
• Temperature (TEMP): Measured simultaneously with air velocity, displayed in °C or °F.
• Volumetric Flow (FLOW): Calculated based on air velocity and a user-defined cross-sectional area.

6.3. Changing Units

Press the "Unit" button to cycle through available measurement units for velocity and temperature.

6.4. Setting Volumetric Flow Area

To measure volumetric flow, you must input the cross-sectional area of the duct or opening:

1. Press the "FLOW/TEMP" button to switch to volumetric flow mode.
2. Use the "SETUP" button to enter the area setting menu.
3. Adjust the area value using the arrow buttons and confirm with "Enter".

6.5. Using Hold, Min/Max, and Mean Functions

• Hold: Press "HOLD/ZERO" to freeze the current display reading. Press again to release.
• Min/Max: Press "MAX/MIN" to view the minimum or maximum recorded values during a measurement session.
• Mean: Press "MEAN" to calculate and display the average value over a period or series of spot measurements.

7. Maintenance

7.1. Cleaning

Keep the device clean to ensure optimal performance.

• Wipe the main unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• The hot-wire sensor on the probe is delicate. Clean it only with a soft brush or compressed air, if absolutely necessary, and with extreme care. Avoid touching the sensor directly.

7.2. Storage

When not in use, store the TA300 in its protective carrying case in a dry, dust-free environment, away from extreme temperatures.

• Ensure the telescopic probe is fully retracted before storage.
• Remove the battery if the device will not be used for an extended period to prevent leakage.

7.3. Calibration

The TA300 comes with a factory calibration certificate. For continued accuracy, periodic recalibration by an authorized service center is recommended, especially for professional applications.
