4. Configuració inicial
- Carregueu el dispositiu: Before first use, connect the Gauss meter to a power source using the provided USB Type-C cable. The built-in lithium battery provides approximately 16 hours of continuous operation on a full charge.
- Connecteu la sonda: Carefully insert the Hall probe into the probe interface on the top of the main unit. Ensure a secure connection.
- Encès: Press and hold the power button (usually located in the key area) to turn on the device.
- Reducció a zero: For accurate measurements, perform a zeroing operation. Place the Hall probe in an area free of magnetic fields and press the 'ZERO' button. The device supports both automatic and manual zeroing.
5. Instruccions de funcionament
5.1 Mesura bàsica
- Ensure the device is powered on and zeroed.
- Position the Hall probe close to the magnetic field you wish to measure.
- The magnetic field strength (in Gs or mT) and polarity (North/South) will be displayed on the color screen.
- Use the 'HOLD' button to freeze the current reading on the screen for closer inspection.
5.2 Quality Test Function
The device features a one-key quality test function to quickly determine if a magnetic field falls within specified upper and lower limits, improving work efficiency.
- Access the quality test menu through the device interface.
- Set the desired upper and lower limits for the magnetic field.
- Place the probe in the magnetic field and initiate the test.
- The screen will display a pass (green checkmark) or fail (red cross) result, along with qualified/unqualified counts.
5.3 Counting Speed Measurement
This function allows for the measurement of rotational speed by detecting a fixed magnet on a rotating object.
- Fix a magnet onto the rotating wheel or object.
- Position the Hall probe close to the fixed magnet.
- As the wheel rotates, the device can measure the rotational speed, mileage, speed, and number of turns.
5.4 Emmagatzematge de dades
The UT335 Series can store up to 50 sets of test data for easy access and review.
- Navigate to the data storage menu on the device.
- Save current measurement data.
- Recall previously saved data for analysis.
5.5 Alarm Methods
The device provides rich alarm methods when detected values exceed or fall below set limits.
- Visualització de la pantalla: Visual alert on the color screen.
- Zumbador: Alarma sonora.
- Llum LED: Visual indication via an LED.
6. Manteniment
- Neteja: Feu servir un drap suau i sec per netejar el dispositiu. No utilitzeu productes de neteja abrasius ni dissolvents.
- Emmagatzematge: Store the Gauss meter in a cool, dry place away from direct sunlight and extreme temperatures.
- Cura de la bateria: Recharge the built-in lithium battery regularly, even if not in use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Cura de la sonda: Handle the Hall probe with care. Avoid bending or subjecting it to excessive force, as this can damage the sensor.

9. Consells d'usuari
- Always perform a zeroing operation before critical measurements to ensure the highest accuracy.
- When measuring, try to keep the Hall probe perpendicular to the magnetic field lines for optimal readings.
- For consistent results in counting speed measurements, ensure the fixed magnet is securely attached and the probe's distance from it is constant.
- Regularly check the battery level, especially before extended use, to avoid interruptions.
