Analytical Balance Maintenance
Analytical balances are precision instruments used in laboratories to measure small masses with high accuracy. Proper maintenance ensures longevity, reliability, and consistent performance.
Daily Maintenance
- Keep the balance clean and free from dust, spills, and chemical residues.
- Wipe the weighing pan with a soft, lint-free cloth.
- Ensure the balance is on a stable, vibration-free surface.
- Check that the balance is level before use.
Calibration
- Use certified calibration weights regularly, following manufacturer guidelines.
- Perform internal or external calibration as recommended.
- Record calibration results for quality assurance and traceability.
Environmental Considerations
- Avoid drafts, direct sunlight, and temperature fluctuations.
- Minimize vibrations by placing the balance on a solid laboratory bench.
- Maintain consistent humidity to reduce measurement variability.
Troubleshooting Common Issues
- Erratic readings: Check level, environmental factors, and calibration.
- Display errors: Inspect power supply, connectors, and internal sensors.
- Pan sticking or mechanical issues: Clean and inspect components carefully.
