4. Setup

4.1 Charging the Device

The BT-5000Y comes with a built-in 600mAh rechargeable lithium battery. Before first use, or when the low battery indicator appears on the display, charge the device using the provided USB Type-C cable.

1. Connect the USB Type-C end of the cable to the charging port on the anemometer.
2. Connect the USB-A end of the cable to a standard USB power adapter (not included) or a computer USB port.
3. The charging indicator on the device will show the charging status. Once fully charged, the indicator will change or turn off.

4.2 Attaching the Probe

The hot-wire sensor probe is detachable for storage and transport. To attach it:

1. Align the connector on the probe cable with the port on the main unit.
2. Gently push and twist the connector until it is securely fastened. Ensure a firm connection to prevent inaccurate readings.

Figure 4.1: The extendable probe can reach up to 800mm, allowing for measurements in various environments.

5. Operation

5.1 Power On/Off

• To power on: Press the Power button (indicated by a circle with a vertical line) located on the front panel.
• To power off: Press and hold the Power button for approximately 2 seconds. The device also features an automatic shutdown function to conserve battery life, which can be configured in the settings.

5.2 Taking Measurements

1. Ensure the probe is securely connected and extended to the desired length.
2. Position the sensor head in the airflow path you wish to measure. Ensure the airflow is directed towards the sensor for accurate readings.
3. The large LCD display will show real-time wind speed, temperature, and airflow data.

5.3 Data Hold Function

To hold the current measurement data on the screen, press the H button. Press it again to release the data hold and resume real-time measurements.

5.4 MAX/MIN/AVG Function

To view the maximum, minimum, or average recorded values:

• Press the MAX/MIN button once to display the maximum wind speed recorded since power-on.
• Press it again to display the minimum wind speed.
• Press it a third time to display the average wind speed.
• Press it a fourth time to return to real-time measurement.

6. Measurement Units and Modes

6.1 Changing Wind Speed Units

The device supports 5 different wind speed units:

• Meters per second (m/s)
• Kilometers per hour (km/h)
• Feet per minute (ft/min)
• Knots (Knots)
• Miles per hour (Mph)

To cycle through these units, press the UNIT button.
