4.2 Power Connection

Connect the universal power supply to the balance and then plug the 120V line cord into a suitable electrical outlet. The balance will perform an initial self-test upon power-up.

4.3 Leveling

The Cubis Balance features automatic motorized leveling. Upon initial setup or relocation, the balance will prompt for leveling or can be initiated via the touchscreen interface. Follow the on-screen instructions to ensure the balance is perfectly level for accurate measurements.

4.4 Initial Calibration (isoCAL)

The balance is equipped with isoCAL, a fully automatic internal temperature- and time-controlled calibration function. It is recommended to perform an initial isoCAL cycle after setup and before first use to ensure optimal accuracy. This can be initiated through the balance's menu system.

5. Operating Instructions

5.1 Touchscreen Interface

The balance features a 5.7" high-resolution color TFT touchscreen. This interface provides interactive guidance for managing weighing tasks, user settings, and system settings. Basic functions can also be accessed via the physical keypad buttons surrounding the screen.

5.2 Basic Weighing

1. Ensure the weighing pan is clean and empty.
2. Press the Tare button (if applicable) or use the touchscreen to zero the balance.
3. Carefully place the sample on the center of the weighing pan.
4. Read the stable weight displayed on the screen.
5. Remove the sample.

5.3 Advanced Applications

The Cubis Balance includes 18 built-in applications customizable for complex lab weighing tasks. Access these applications through the touchscreen menu. Examples include:

• Unit Conversion: Change between various weighing units (g, kg, ct, lb, oz, ozt, grain, dwt, mg, parts per pound, Austrian carat, Newton, lb:oz, microgram).
• SQmin Function: For minimum initial weight according to USP standards.
• Density Determination: Calculate the density of samples.
• Formulation: For multi-component weighing processes.
• Counting: Determine the number of pieces based on a reference weight.
• Checkweighing: Verify if a sample's weight falls within a defined tolerance range.
• Statistics: Perform statistical analysis on a series of weighings.

5.4 Calibration

Regular calibration is crucial for maintaining accuracy.

• isoCAL (Internal Calibration): The balance automatically performs internal calibration based on temperature and time changes. This function can also be manually initiated via the menu.
• External Calibration: The balance supports calibration using external weights. Refer to the on-screen prompts or the detailed menu instructions for the procedure.

5.5 Data Interfaces

The balance offers multiple interfaces for data management:

• USB Port: For connecting to a computer (Windows OS) for data transfer.
• RS-232C Port: For connecting peripheral devices.
• Ethernet Port: For network integration.
• SD Card Reader: For importing and exporting data.

6. Maintenance

6.1 Cleaning

To clean the balance, disconnect it from the power supply. Use a soft, damp cloth with a mild detergent. Do not use abrasive cleaners or solvents. Ensure no liquids enter the balance housing. The weighing pan can be removed for separate cleaning.

6.2 General Care

Protect the balance from dust and debris when not in use. Avoid placing heavy objects on the weighing pan when the balance is off. The balance is IP54 certified, providing protection against dust and water splashes from all directions.

7. Troubleshooting

If you encounter issues with your balance, consider the following common solutions:

• Inaccurate Readings: Check if the balance is level. Perform an isoCAL or external calibration. Ensure the environment is stable and free from drafts or vibrations.
• Display Not Working: Verify the power connection. Ensure the power supply is functioning correctly.
• Balance Not Responding: Try restarting the balance by disconnecting and reconnecting the power.
