Operating Instructions
Basic Magnetic Field Measurement
- Power on the device by pressing the power button.
- Ensure the Hall probe is connected.
- Perform a zero calibration if necessary. The device supports both manual and automatic zero calibration.
- Position the Hall probe perpendicular to the magnetic field source for optimal accuracy. The device will display the magnetic field strength in Gauss (Gs) or milliTesla (mT) and indicate the magnetic pole (N/S).

This image demonstrates the correct positioning of the Hall probe, perpendicular to the magnetic field, for accurate measurement with 5% accuracy and a range up to 25,000 Gs.
Alarm Function
The 8103 Gauss Meter features audible and visual alarms. These alarms activate when the measured magnetic field strength exceeds predefined thresholds. The alarm threshold is adjustable through the device's menu.

This image shows the Gauss Meter's alarm function in action, with visual and auditory alerts indicating a threshold exceedance. The alarm settings can be customized.
Data Hold and Storage
Press the "HOLD" button to freeze the current measurement on the screen. The device can store up to 50 readings, allowing for easy tracking and review of key measurement values. Access stored data through the device's menu.

Calibration
The device supports both manual and automatic zero calibration to maintain measurement accuracy. Refer to the on-screen menu for calibration options. The device is factory-calibrated and complies with international standards.
Maintenance
- Keep the device and Hall probe clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the Gauss Meter in its protective storage case when not in use to prevent damage.
- Avoid exposing the device to extreme temperatures, humidity, or strong magnetic fields that are not being measured.
- Recharge the battery regularly to ensure optimal performance and longevity.
Troubleshooting
Device Not Powering On
- Ensure the battery is charged. Connect the device to the Type-C charging cable and allow it to charge for at least 30 minutes before attempting to power on again.
- Verify the power button is pressed firmly.
Inaccurate Readings
- Check if the Hall probe is securely connected to the main unit.
- Ensure the Hall probe is positioned correctly (perpendicular to the magnetic field source).
- Perform a zero calibration.
- Verify that the measurement is within the device's specified range (0-2500 mT for DC magnetic fields).
Alarm Not Functioning
- Check the alarm settings in the device's menu to ensure thresholds are correctly set and the alarm is enabled.
- Verify that the measured magnetic field strength actually exceeds the set alarm threshold.
