5. Setup
5.1 Initial Charging
Before first use, ensure the BT-5000G is fully charged. Connect the provided USB Type-C cable to the charging port on the side of the device and to a standard USB power adapter (not included). The low power indicator on the display will show charging status.
5.2 Power On/Off
- To power on, press and hold the Power Button (usually marked with a circle and a vertical line) until the LCD display illuminates.
- To power off, press and hold the Power Button again until the display turns off.
5.3 Tripod Mounting (Optional)
For continuous or stationary measurements, the BT-5000G can be mounted on a standard tripod using the 1/4" metal screw hole at its base. Ensure the tripod is stable before mounting the device.
6. Operation
6.1 Basic Measurement
Once powered on, the device will display current wind speed and temperature. The 360° rotatable wind cup allows for accurate readings regardless of the device's orientation relative to the wind source.

6.2 Changing Units
Press the UNIT Button to cycle through available units for wind speed, air flow, and temperature.
- Wind Speed Units: m/s, ft/min, Knots, Km/h, mph
- Air Flow Volume Units: CFM, CMM, CMS
- Temperature Units: °C, °F
6.3 Max/Min Measurement Modes
To view the maximum or minimum recorded values during a measurement session:
- Press the MAX/MIN Button once to display the maximum wind speed or air flow value.
- Press it again to display the minimum wind speed or air flow value.
- Press it a third time to return to current measurement mode.

6.4 Data Hold
To freeze the current reading on the display, press the HOLD Button (if available, or typically a short press of the Power button or a dedicated button). Press it again to release the hold and resume live measurements.
6.5 Backlight Control
Press the Backlight Button (often indicated by a light bulb icon) to turn the LCD backlight on or off for improved visibility in various lighting conditions.
6.6 Air Flow Volume (CFM/CMM/CMS) Measurement
To measure air flow volume, you may need to input the area of the duct or vent. Refer to the device's on-screen prompts or the SET Button for area input. The device will then calculate and display the air flow volume based on the measured wind speed and the entered area.

6.7 Applications
The BT-5000G is versatile for both industrial and daily applications:
- Industrial: HVAC systems, dust collectors, ventilation systems.
- Daily: Drone driving, parachuting, sailing, golf, hiking, hunting, shooting, gliding.
