5. Operating Instructions
The 8103 Gauss Meter offers various functions for magnetic field measurement.
5.1 Basic Measurement
To take a measurement, hold the Hall probe near the magnetic field source. The device will display the magnetic field strength in Gs (Gauss) or mT (milliTesla) and indicate the magnetic pole direction (N/S). Ensure the probe is positioned correctly for accurate readings.
5.2 Data Hold and Storage
Press the 'Hold' button to freeze the current reading on the display. The device can also automatically record maximum values, allowing for easy review of key measurements. Refer to the on-screen menu for data storage and retrieval options.
5.3 Alarm Function
The meter features audible and visual alarms. These alarms activate when the measured magnetic field strength exceeds user-defined thresholds. The alarm threshold is adjustable through the device settings.

5.5 Zero Calibration
The device supports both manual and automatic zero calibration to maintain measurement accuracy. Perform calibration in an environment free from magnetic interference.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your Gauss Meter.
- Cleaning: Use a soft, dry cloth to clean the device and probe. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its provided storage case in a cool, dry place when not in use. Avoid areas with strong magnetic fields.
- Battery Care: Recharge the battery regularly, even if the device is not frequently used, to maintain battery health.
7. Troubleshooting
If you encounter issues with your Gauss Meter, try the following:
- 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.
- Inaccurate readings: Perform a zero calibration in a magnetically neutral environment. Check if the Hall probe is securely connected and undamaged.
- No display: Check battery level. If the screen remains blank after charging, contact customer support.
