- Control Panel: Buttons for power, tare, calibration, and menu navigation.
- Leveling Feet: Adjustable feet to ensure the scale is perfectly level.
4. Setup
4.1 Unpacking
Carefully remove the scale and all accessories from the packaging. Retain the original packaging for future transport or storage.
4.2 Placement
Place the scale on a firm, stable, and level surface. Avoid locations subject to:
- Direct sunlight or heat sources.
- Strong air currents (drafts from doors, windows, or air conditioning).
- Vibrations from machinery or heavy traffic.
- Rapid temperature changes.
4.3 Leveling the Scale
Adjust the leveling feet located at the bottom of the scale until the air bubble in the level indicator (usually located near the display) is centered. This ensures accurate weighing results.
4.4 Power Connection
Connect the provided power adapter to the scale's power input and then to a suitable electrical outlet. Allow the scale to warm up for at least 30 minutes after initial power-on for optimal stability.
5. Operating Instructions
5.1 Power On/Off
Press the Power button (often marked with a circle and a vertical line) to turn the scale on or off. The display will show a self-test sequence before settling at zero.
5.2 Basic Weighing
- Ensure the display reads 0.00 g before placing any item on the pan.
- Carefully place the item to be weighed onto the center of the weighing pan.
- Wait for the reading to stabilize. The stable reading will be displayed.
- Remove the item from the pan.
5.3 Tare Function
The tare function allows you to weigh items in a container by subtracting the container's weight.
- Place the empty container on the weighing pan.
- Press the Tare button (often marked with a 'T' or '->0<-'). The display will reset to 0.00 g.
- Add the item to be weighed into the container. The display will show the net weight of the item.
- Remove both the item and container from the pan.
6. Calibration
The Sartorius GL2202i-2S features an automatic, built-in calibration and adjustment function. Regular calibration ensures the highest level of accuracy. Refer to the on-screen prompts or the scale's specific menu for initiating the automatic calibration process. Ensure the scale is stable and free from any load during calibration.
7. Maintenance and Cleaning
7.1 Cleaning
To maintain the scale's performance and appearance:
- Disconnect the scale from the power supply before cleaning.
- Wipe the exterior surfaces with a soft, damp cloth and a mild detergent.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
- Ensure no liquids enter the scale's housing or display area.
- The stainless steel weighing pan can be removed and cleaned separately with appropriate cleaning agents.
7.2 Storage
If storing the scale for an extended period, ensure it is clean, dry, and stored in its original packaging or a protective container in a stable environment.
8. Troubleshooting
This section addresses common issues you might encounter. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "Err" or unstable readings. | Scale not level, vibrations, drafts, overload, or internal error. | Check leveling, move to a stable location, ensure no load exceeds capacity, restart the scale. |
| Scale does not power on. | Power cable disconnected, faulty outlet, or power adapter issue. | Verify power cable connection, try a different outlet, check power adapter. |
| Inaccurate readings. | Needs calibration, environmental factors, or dirty pan. | Perform calibration, ensure stable environment, clean weighing pan. |
