Operation

1. Powering On/Off

Press and hold the power button (usually located on the side or front) for a few seconds to turn the device on or off. The display will illuminate upon power-on.

2. Navigating the Interface

The chronograph features a clear display and intuitive controls. Use the designated buttons to navigate through menus, select measurement modes, and view stored data. Refer to the on-screen prompts for specific button functions.

3. Taking a Measurement

1. Ensure the chronograph is powered on and in the correct measurement mode (e.g., velocity measurement).
2. Position the projectile source (e.g., bow, air rifle) so that the projectile will pass cleanly through the sensor area of the chronograph.
3. Fire the projectile. The device will automatically detect the projectile's passage and display the velocity reading.
4. The measurement range is 1-2000 m/s, providing precise readings for various projectiles.

4. Reviewing Data

The device may store previous measurements. Use the navigation buttons to scroll through historical data if this feature is available.

Maintenance

Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor areas are free from dust and debris for optimal performance.

Storage

Store the chronograph in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Ensure the battery is partially charged (around 50%) for long-term storage to prolong battery life.
