Key Features
- isoCAL Internal Calibration: Ensures consistent accuracy without manual intervention.
- LED Touch Technology: Intuitive and user-friendly interface for easy navigation.
- 12 Built-in Applications: Includes Weighing, Dosing, Counting, Percentage weighing, Net total, Totalizing, Animal weighing, Calculation, Density, Statistics, Peakhold, Checkweighing, Mass unit conversion, and Underfloor weighing.
- High Readability: Measures with a readability of 0.1 mg.
- Draft Shield: Manual adjustment draft shield to minimize environmental interference.
- Connectivity: Equipped with RS232 and USB-C interfaces for data transfer.
- Robust Design: Built with German engineering expertise for durability.
Setup
- Unpacking: Carefully remove the balance and all accessories from the packaging. Retain packaging for future transport or storage.
- Placement: Place the balance on a stable, level, and vibration-free surface, away from direct sunlight, drafts, and heat sources.
- Leveling: Use the integrated level indicator and adjustable feet to ensure the balance is perfectly level. Adjust the feet until the air bubble is centered within the circle.
- Assembly: Assemble the draft shield components and weighing pan according to the diagrams in the quick start guide. Ensure all parts are clean and properly seated.
- Power Connection: Connect the power adapter to the balance and then to a suitable power outlet (100 – 240 VAC, 50 – 60 Hz).
- Initial Power On: Turn on the balance using the power button. Allow it to warm up for at least 30 minutes for optimal stability before use.
Operating Instructions
Basic Weighing
- Power On: Ensure the balance is powered on and has completed its warm-up phase.
- Zeroing/Taring: If a container is used, place it on the weighing pan and press the TARE button to set the display to zero.
- Placing Sample: Carefully place the sample to be weighed onto the weighing pan or into the tared container. Close the draft shield doors to prevent air currents from affecting the reading.
- Reading Measurement: Wait for the stability indicator (usually a circle or star) to appear on the display, indicating a stable reading. Read the weight displayed on the LED screen.
- Removing Sample: Remove the sample and container. The display will show a negative value if tared. Press TARE again to return to zero, or ZERO if no container was used.
Using Applications
The Entris II BCE224I-1S features 12 built-in applications accessible via the LED touch screen. To select an application:
- Navigate to the main menu on the touchscreen.
- Select the desired application (e.g., Counting, Density, Percentage weighing).
- Follow the on-screen prompts specific to each application for inputting parameters or performing measurements.
Maintenance
- Cleaning: Regularly clean the weighing pan, draft shield, and exterior surfaces with a soft, lint-free cloth dampened with mild detergent or isopropyl alcohol. Do not use abrasive cleaners or solvents. Ensure no liquids enter the balance housing.
- Calibration: The balance features isoCAL internal calibration. It is recommended to perform external calibration periodically using a certified 200 g | E2 calibration weight to ensure maximum accuracy, especially after relocation or significant temperature changes. Refer to the balance's on-screen menu for external calibration procedures.
- Environmental Control: Maintain a stable environment. Avoid extreme temperature fluctuations, high humidity, and strong air currents.
- Inspection: Periodically inspect the power cord for damage and ensure all connections are secure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unstable readings | Vibrations, drafts, temperature fluctuations, unlevel balance. | Ensure stable surface, close draft shield, allow warm-up, level the balance. |
| Balance does not turn on | Power cord disconnected, faulty power outlet. | Check power connections, try a different outlet. |
| Inaccurate measurements | Needs calibration, dirty weighing pan, incorrect application settings. | Perform calibration, clean weighing pan, verify application settings. |
| Display shows "Error" message | Overload, internal malfunction. | Remove excess weight, power cycle the balance. If persistent, contact support. |
