6. Calibration

The Sartorius Secura 225D-1S features isoCAL, an internal, fully automatic calibration and adjustment function. This ensures high accuracy and compliance with regulatory requirements.

6.1. Automatic Internal Calibration (isoCAL)

The balance performs isoCAL automatically at regular intervals, after changes in temperature, or if a defined time interval has elapsed. No user intervention is typically required for routine internal calibration.

6.2. Manual External Calibration

For specific applications or regulatory requirements, manual external calibration with certified weights may be necessary. Consult the on-screen menu for instructions on initiating a manual calibration procedure. Ensure you use appropriate OIML Class E1 or E2 calibration weights for optimal accuracy.

7. Maintenance

7.1. Cleaning

• Disconnect the balance from the power supply before cleaning.
• Use a soft, damp cloth with a mild, non-abrasive cleaning agent to clean the exterior surfaces.
• The weighing pan and draft shield components can be removed and cleaned separately with warm water and a mild detergent. Ensure they are completely dry before reassembly.
• Do not use harsh chemicals, solvents, or abrasive materials, as these can damage the balance's finish or internal components.

7.2. Care and Storage

• When not in use, keep the draft shield closed to protect the weighing system from dust and debris.
• Store the balance in a clean, dry environment within the specified operating temperature range.
• Avoid dropping or subjecting the balance to sudden impacts.
