4.3 Reading the Display
The FMX-003 features a bicolor LCD display:
- Numerical Reading: Shows the exact voltage value.
- Bar Graph: Provides a graphical representation of the field strength.
- Polarity: Red LCD indicates positive polarity voltage, while blue LCD indicates negative polarity voltage.
- Battery Status: An icon on the display indicates the current battery level.
5. Maintenance
5.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the housing or display. Ensure the measuring plate is kept clean for accurate readings.
5.2 Battery Replacement
When the battery indicator shows low power, replace the 9V battery as described in Section 3.1. Prompt battery replacement ensures consistent performance.
5.3 Storage
Store the FMX-003 in its protective carrying case in a dry environment, away from extreme temperatures and direct sunlight, when not in use.
6. Troubleshooting
- Device does not power on: Check if the 9V battery is correctly installed and has sufficient charge. Replace if necessary.
- Inaccurate or inconsistent readings:
- Ensure the measuring distance is consistently 1 inch (25mm) using the LED guides.
- Press the ZERO button before each measurement.
- Verify the device is properly grounded.
- Clean the measuring plate and surrounding area.
- Display issues: If the display is dim or flickering, replace the battery.
