Unit Switching

• Magnetic/Electric Field Units: Press the MG/UT button to switch between milliGauss (mG) and microTesla (µT) units for electromagnetic field readings.
• Temperature Units: Press the °C/°F button to toggle between Celsius (°C) and Fahrenheit (°F) for temperature display.

Backlight and Data Hold

• Backlight: Briefly press the Mode button to turn the LCD backlight on or off, improving visibility in different lighting conditions.
• Data Hold: Press and hold the Mode button to activate the data hold function, which locks the current readings on the display. Press again to release.

Alarm Function

The device features an intelligent alarm system. If the detected electromagnetic radiation exceeds the preset safe value, the instrument will automatically trigger a sound and light alarm. This provides immediate notification of potentially high radiation levels.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure accurate readings.
• Avoid Impact: Protect the device from drops and strong impacts, which can damage internal components.

Troubleshooting

Common Issues and Solutions

• Device does not power on:
  • Check if batteries are installed correctly with the right polarity.
  • Replace with fresh AAA batteries.
• Inaccurate or fluctuating readings:
  • Ensure the device is held steadily and away from other electronic devices that might interfere with readings.
  • Verify that the sensor position is correctly oriented towards the source of measurement.
• Display is dim or unreadable:
  • Check battery level and replace if low.
  • Activate the backlight by briefly pressing the Mode button.
• Alarm sounds continuously:
  • This indicates high electromagnetic radiation. Move away from the source or investigate the environment.
  • Ensure the alarm threshold is set appropriately (if adjustable, though this model's setting is fixed at 40mG/0.4µT).
