1. Introduction
This manual provides comprehensive instructions for the proper setup, operation, and maintenance of the Sartorius Secura224-1S Analytical Balance. Designed for high-precision weighing in laboratory environments, the Secura224-1S ensures accurate and reliable measurement results. Please read this manual thoroughly before operating the device to ensure safe and correct usage.
2. Safety Information
Observe the following safety precautions to prevent injury and damage to the balance:
- Operate the balance only in a stable, level, and vibration-free environment.
- Ensure the power supply matches the specifications indicated on the balance.
- Do not expose the balance to extreme temperatures, humidity, or direct sunlight.
- Avoid dropping or subjecting the balance to strong impacts.
- Do not attempt to open or repair the balance yourself. Refer servicing to qualified personnel.
- Keep the balance clean and free from dust and chemical spills.
3. Product Overview
3.1 Features
- Readability: 0.1 mg for precise measurements.
- Weighing Range: Up to 220 g capacity.
- Draft Shield: Manual draft shield to minimize air current interference.
- Interface: Mini USB interface for data connectivity.
- Isocal: Internal calibration system for consistent accuracy.
3.2 Components
The Secura224-1S features a robust design with a clear manual draft shield, a high-resolution digital display, and a weighing pan. The draft shield protects the weighing process from air currents, which is crucial for measurements at 0.1 mg readability.
4. Setup
4.1 Unpacking and Placement
- Carefully remove the balance from its packaging. Retain packaging for future transport.
- Place the balance on a stable, level, and vibration-free surface, away from direct sunlight, heat sources, and air currents (e.g., vents, open windows).
- Ensure sufficient space around the balance for operation and maintenance.
4.2 Leveling the Balance
The balance must be perfectly level for accurate measurements.
- Locate the spirit level (bubble level) on the balance.
- Adjust the leveling feet at the base of the balance until the air bubble is centered within the circle of the spirit level.
4.3 Power Connection
- Connect the power adapter to the balance and then to a suitable power outlet.
- Allow the balance to warm up for at least 30 minutes after initial power-on to ensure stable readings.
5. Operating Instructions
5.1 Basic Weighing Procedure
- Ensure the draft shield doors are closed.
- Press the ON/OFF button to power on the balance.
- Wait for the display to show "0.0000 g" or a stable zero reading.
- Open the draft shield door, carefully place the item to be weighed onto the center of the weighing pan.
- Close the draft shield door.
- Wait for the reading to stabilize. The stable weight will be displayed.
- To tare (zero out the weight of a container), place the empty container on the pan and press the TARE button. The display will return to zero. Then add the substance to be weighed into the container.
5.2 Calibration (Isocal)
The Sartorius Secura224-1S features an internal automatic calibration system (Isocal) to ensure optimal accuracy. Regular calibration is essential for precise measurements.
- The balance may perform automatic calibration at set intervals or when environmental conditions change significantly.
- Refer to the on-screen menu or the full technical manual for instructions on initiating manual internal calibration if required.
- During calibration, ensure no items are on the weighing pan and the draft shield is closed.
5.3 Using the Mini USB Interface
The Mini USB interface allows for data transfer to a computer or other compatible devices.
- Connect the balance to a computer using a Mini USB cable (not included).
- Install any necessary drivers or software provided by Sartorius (refer to the official Sartorius website for downloads).
- Follow the software instructions to configure data output and capture weighing results.
6. Maintenance
6.1 Cleaning
- Always disconnect the balance from the power supply before cleaning.
- Use a soft, damp cloth with a mild detergent to clean the exterior surfaces.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the balance.
- Carefully clean the weighing pan and draft shield components. These parts may be removable for easier cleaning.
- Ensure no liquids enter the internal components of the balance.
6.2 Storage
When not in use for extended periods, store the balance in a clean, dry, and temperature-controlled environment. Keep the draft shield closed to protect the weighing pan.
7. Troubleshooting
If you encounter issues with your Sartorius Secura224-1S balance, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unstable readings | Vibrations, air currents, unlevel balance, temperature fluctuations. | Ensure stable surface, close draft shield, level the balance, allow warm-up time. |
| Balance does not turn on | No power supply, faulty power adapter. | Check power connection, test power outlet, ensure adapter is functional. |
| Inaccurate measurements | Needs calibration, foreign objects on pan, environmental factors. | Perform internal calibration (Isocal), clean weighing pan, check environment. |
| Display error message | Overload, internal fault. | Remove excess load, power cycle the balance. If persistent, contact support. |
For issues not listed here or if problems persist, please contact Sartorius customer support.
