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交流研討。
  a. 穿戴適當?shù)膫€人防護裝備（外套凝聚力量、護目鏡和手套）有效保障。
  b. 查閱操作說明至關重要，了解如何拆卸和重新組裝秤的可拆卸部件建議。
  c. 查閱操作說明和/或用戶手冊堅實基礎，了解清潔秤部件的推薦清潔劑。
• 關(guān)閉秤顯示屏更適合。
  建議拔掉電源高效，但這不是必須的。如果可能要素配置改革，請將秤保持在正常操作位置體系，不要將其傾斜到一邊，也不要拔下連接的外圍設(shè)備帶動產業發展。
• 清潔秤周圍的區(qū)域責任製。
  使用干凈、干燥的無絨布清除設(shè)備周圍的任何污垢必然趨勢，以避免進一步污染促進善治。
• 移除負載板擴大。
  負載板應(yīng)易于移除多樣性。取下它不需要硬物，也不應(yīng)該使用硬物新格局。不要拆卸稱重平臺明顯。
• 清潔秤的內(nèi)部框架和終端。
  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顯示。
  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)部的污垢和沉積物創新為先。
• 清潔負載板。
  使用濕布并用含有乙醇的溫和清潔劑（例如科普活動，商用窗戶清潔劑）清潔創新延展。
• 重新組裝秤。
  確保零件位置正確長期間，打開秤并檢查其是否正常工作基本情況。如果完全關(guān)閉，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）高端化。
• 將秤調(diào)平力量。
  a. 確保氣泡位于標記圓圈的中心，如果不在提單產，請采取適當措施重新調(diào)平高效流通。
  b. 在稱重盤上放置測試砝碼并執(zhí)行常規(guī)測試以檢查準確性調解製度。
  c. 如果未通過此常規(guī)測試，請使用外部砝碼校準秤或執(zhí)行內(nèi)部校準功能，例如 FACT應用的因素之一。
  d. 測試配件（例如，為打印機制作測試打印輸出）預期。

General Industrial Scale Cleaning Procedures

• Be prepared: Protect yourself and have instructions ready.
• 關(guān)閉秤顯示屏善於監督。
  如果可能，請將秤保持在正常工作位置就能壓製。
• 清潔秤周圍更合理。
  使用干凈的干無絨布清除秤周圍的任何污垢。
• 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.
