Scope This SOP describes procedures for cleaning industrial (benchtop) scales. Designed to instruct personnel on how to thoroughly clean a scale. Scale cleanliness can have a significant impact on operating efficiency and scale longevity, as well as user safety.

Things to note

• Make sure personnel know how to clean the scale and refer to the instructions and guidelines in the user manual.
• First remove excess powder and dust, then remove gunk.
• For excess powder and dust, use a clean, dry cloth.
• Remove the weighing plate according to the instructions in the user manual.
• Remove any dirt and foreign matter that may have accumulated beneath it. (Do not use any hard objects to do this. Do not disassemble the weighing platform.)
• Remove dirt and sediment from the outside and inside of the weighing platform using a soft, clean cloth moistened with appropriate detergent.
• Only use cleaning agents that will not affect the plastic used in the weighing platform and comply with the manufacturer's instructions.
• Do not use strongly acidic, alkaline or chlorinated cleaners. Avoid using substances with a pH that is too high or too low as this increases the risk.
• All cleaners should be rinsed thoroughly according to the instructions in the user manual.
• Take special care when cleaning the load cells of our high-precision models. Never touch, blow or spray the load cell cover directly with compressed air.
• The most appropriate cleaning procedure depends on the type of surface and environmental conditions (dry, wet or corrosive). The instructions in the user manual should always be followed.
• Stainless steel models require subsequent oiling for proper maintenance.
• See the user manual for detailed instructions.

Cleaning Frequency Cleaning frequency varies depending on the industry, application and frequency of instrument use. In general, it is recommended to clean the scale at least after every shift or product line change. If there is a spill, the entire area should be cleaned before weighing another material. When handling potentially toxic substances, the scale must always be cleaned after use. Cleaning Procedure The following steps describe a general cleaning procedure that applies to all bench scales. Depending on the type and model of scale you have, some of the steps listed below may not work. Standard cleaning procedures

• 做好準備：保護自己并準備好說明實事求是。
  a. 穿戴適當?shù)膫€人防護裝備（外套系統、護目鏡和手套）應用提升。
  b. 查閱操作說明，了解如何拆卸和重新組裝秤的可拆卸部件。
  c. 查閱操作說明和/或用戶手冊，了解清潔秤部件的推薦清潔劑改善。
• 關(guān)閉秤顯示屏。
  建議拔掉電源協調機製，但這不是必須的信息化。如果可能，請將秤保持在正常操作位置實踐者，不要將其傾斜到一邊取得明顯成效，也不要拔下連接的外圍設(shè)備。
• 清潔秤周圍的區(qū)域數據。
  使用干凈使用、干燥的無絨布清除設(shè)備周圍的任何污垢，以避免進一步污染發行速度。
• 移除負載板更加堅強。
  負載板應(yīng)易于移除。取下它不需要硬物性能，也不應(yīng)該使用硬物初步建立。不要拆卸稱重平臺。
• 清潔秤的內(nèi)部框架和終端組建。
  使用蘸有溫和清潔劑的干凈無絨布清潔并清除秤表面上的任何溢出物各有優勢。
  a. 使用蘸有溫和清潔劑的柔軟干凈布擦去稱重平臺外部和內(nèi)部的污垢和沉積物。
• 清潔負載板重要的意義。
  使用濕布并用含有乙醇的溫和清潔劑（例如持續，商用窗戶清潔劑）清潔。
• 重新組裝秤再獲。
  確保零件位置正確產品和服務，打開秤并檢查其是否正常工作。如果完全關(guān)閉體驗區，請在首次使用前留出足夠的預(yù)熱時間（查看操作說明以了解制造商的建議）增多。
• 將秤調(diào)平。
  a. 確保氣泡位于標記圓圈的中心有望，如果不在進一步推進，請采取適當措施重新調(diào)平。
  b. 在稱重盤上放置測試砝碼并執(zhí)行常規(guī)測試以檢查準確性方案。
  c. 如果未通過此常規(guī)測試應用的選擇，請使用外部砝碼校準秤或執(zhí)行內(nèi)部校準十大行動，例如 FACT。
  d. 測試配件（例如背景下，為打印機制作測試打印輸出）綜合措施。

General Industrial Scale Cleaning Procedures

• Be prepared: Protect yourself and have instructions ready.
• 關(guān)閉秤顯示屏。
  如果可能自然條件，請將秤保持在正常工作位置設計標準。
• 清潔秤周圍。
  使用干凈的干無絨布清除秤周圍的任何污垢互動互補。
• Remove the load plate.
• Clean the inside and outside of the scale.
• Clean the load board.
• Reassemble the scale.
• Check the leveling of the scale and perform routine tests if necessary.
