The core of the maintenance and care of stainless steel weights is Anti-pollution, anti-corrosion, impact-resistant, and subject to regular calibration. , to ensure long-term accuracy and stability. The complete operating procedure is as follows:
I. Daily Usage Guidelines (Most Critical)
- Pick up and put down : Use for under 50g Specialized tweezers / forceps ; kilogram-level戴 Powder-Free Latex Gloves / Fine Yarn Gloves ， Strictly prohibited to touch with bare hands. (Sweat contains salt, which can easily cause corrosion.)
- Operation : Handle with care, Strictly prohibit impact, dropping, and compression. ; Do not store together with other metals or hard objects; return to the designated box immediately after use.
- Environment : Do not use in humid, high-salt-fog, acidic/alkaline, strong-magnetic-field, or high-temperature environments; before calibration, ensure the weights and the balance Maintain constant temperature for more than 2 hours 。
II. Cleaning and Maintenance (Must be performed after each use)
- Daily Cleaning : use Lint-free cloth / Suede / Silk dip Anhydrous ethanol Gently wipe to remove dust, fingerprints, and moisture. Completely dry Store it again later.
- Stubborn Stains : For oils and fats Neutral detergent Wipe locally, rinse thoroughly with clean water, and dry immediately; acid or alkali residues Rinse immediately with copious amounts of water. Then treat with 10% nitric acid or a dedicated stainless steel cleaning agent, and finally wipe dry with alcohol.
- Strictly prohibited : use Steel wool, sandpaper, hard tools Polishing; do not use strong acids, strong alkalis, or abrasive cleaners; weights with adjustment cavity Prevent liquid from penetrating the interior 。
III. Storage Management (the Foundation for Long-Term Stability)
- Environment : Dry, clean, well-ventilated, and free of corrosive gases; temperature 18–22°C , humidity 40%–60% ; Keep away from magnetic fields, vibration sources, and high-temperature equipment.
- Container : Put back Original Dedicated Weight Box , place in the box Desiccant ; Different grades / specifications Store separately , to avoid friction and collisions.
- Long-term idleness : each 3–6 months Clean and inspect once; can be coated. Trace Amount Rust-Preventive Oil Store in a sealed container afterward.
IV. Regular Inspection and Calibration (to Ensure Accuracy Compliance)
- Visual Inspection : Check monthly for any Rust, scratches, deformation, and defects , immediately suspend and send for inspection in case of abnormalities.
- Periodic Calibration : Submit for inspection in accordance with statutory / metrological requirements:
- Level E1/E2/F1: Once a year
- F2/M1 Level: Once every 1–2 years
- Record : Establish a ledger to record information on usage, cleaning, calibration, and verification, facilitating traceability.
V. Troubleshooting Common Issues
- Minor rust / oxidation : Gently wipe with an alcohol swab; in severe cases Return to factory for re-polishing + calibration ， Self-grinding is prohibited. 。
- Magnetization : Stay away from magnetic fields; if necessary, do Demagnetization processing 。
- Deformation / Defect : Immediately disable and send to a professional service center for repair or replacement.
VI. Mnemonic for Maintenance and Servicing
Do not touch with hands; handle gently. Wipe with alcohol and allow to dry thoroughly. Use a desiccant box to protect against magnetic fields. Perform regular calibration and maintain accurate records.
