5. Návod k obsluze
5.1 Základní měření
- 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 Funkce testu kvality
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.
- Umístěte Hallovu sondu blízko pevného magnetu.
- As the wheel rotates, the device can measure the rotational speed, mileage, speed, and number of turns.
5.4 úložiště dat
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.
- Displej: Visual alert on the color screen.
- Bzučák: Zvukový alarm.
- LED světlo: Visual indication via an LED.
6. Údržba
- Čištění: K čištění zařízení používejte měkký, suchý hadřík. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
- Skladování: Store the Gauss meter in a cool, dry place away from direct sunlight and extreme temperatures.
- Péče o baterie: Recharge the built-in lithium battery regularly, even if not in use, to maintain battery health. Avoid fully discharging the battery for extended periods.
- Péče o sondu: S Hallovou sondou zacházejte opatrně. Neohýbejte ji ani ji nevystavujte nadměrné síle, mohlo by dojít k poškození senzoru.

9. Uživatelské tipy
- 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.
