如何校準數位比例:逐步指南
校準可確保您的秤提供準確的讀數。 即使是品質尺度也會隨著時間的推移而漂移,新的尺度也常常未經校準。 本指南涵蓋了您需要了解的有關保持秤準確的所有資訊。
快速回答
校準:在穩定表面上開啟刻度,進入校準模式(通常按住 CAL 按鈕),等待讀數為零,提示時放置所需的校準重量,等待確認。 每月校準,滴後或讀數似乎關閉時。 大多數秤需要 50g、100g 或 200g 校準重量。
為什麼校準很重要?
For metrology and calibration science, BIPM(國際重量與措施局) sets international measurement standards.
沒有校準會發生什麼事
- 讀數偏離真實重量
- 小錯誤隨著時間的推移而複合
- 無法準確驗證購買
- 給藥變得不可靠
- 可能認為好的規模壞了
何時校準
絕對校準:
- 新比例(開箱即用)
- 掉落或不和諧後
- 溫度變化後
- 定期使用每月
- 當讀數似乎關閉時
需要進行標誌校準:
- 每次對同一項項目有不同的讀數
- 已知的重量 讀數不正確
- 顯示不會正確歸零
- 讀數似乎始終如高或低
你需要什麼?
校準重量
包括重量:
許多精密刻度包括校準重量。 檢查您的方框或比例箱。
購買重量:
- 線上購買(套裝 5-15 美元)
- 在主店出售
- 珠寶用品店
共同校準重量:
- 50g
- 100g
- 200g
- 500g
您的秤要求:
檢查手動或校準模式顯示,以查看您的秤需要什麼重量。
DIY 替代方案
美國硬幣作為校準檢查:
使用硬幣:
- 堆疊多重以獲得較大的重量
- 10 鎳 = 50g
- 20 鎳 = 100 克
限制:
- 不如校準重量精確
- 磨損的硬幣可能更輕
- 適合檢查,不適合精確校準
步次校準
步驟 1:準備你的體重計
Setup:
- 放置在平坦、穩定、堅硬的表面上
- 避免地毯、桌布
- 遠離通風口和氣流
- 室溫環境
Power on:
- 打開比例尺
- 讓它熱身(30 秒)
- 顯示應該顯示 0.0g
- 確保沒有什麼接觸平台
步驟2:進入校準模式
常用方法:
- 按住 Cal 按鈕直到顯示“cal”
- 按住模式按鈕 3-5 秒
- 同時按下看去+模式
- 用紙本按下隱藏按鈕
查閱你的手冊 for exact procedure—varies by model.
你會看到什麼:
- 展出的“cal”
- 閃爍數字(所需重量)
- “0.0” 等待零校準
步驟 3:零校準
大多數校準的第一步:
- 顯示 0.0 或類似
- 確保平台為空
- 完全不觸及比例
- 按下按鈕確認零點
發生了什麼事:
比例正在記錄“零重量”基線。 任何干擾都會造成不準確的基線。
步驟 4:放置校準重量
提示時:
- 顯示顯示所需的重量(例如,「100」)
- 輕輕放置校準重量
- 將其放在平台上
- 完全移除你的手
- 等待閱讀穩定
Critical:
- 使用指示的確切重量
- 不要減肥
- 校準時不要觸及刻度
步驟 5:確認
成功指標:
- 顯示顯示“通過”
- 顯示顯示“結束”
- 鱗片嗶嗶聲
- 恢復正常稱重模式
如果校準失敗:
- 顯示顯示“失敗”或“錯誤”
- 請參閱下面的故障排除部分
步驟 6:驗證
校準後,測試:
- Weigh calibration weight (should be exact)
- Weigh known items (coins, etc.)
- Try multiple items
- Check consistency
Troubleshooting Calibration Issues
"FAIL" or "ERR" Display
Causes:
- Wrong calibration weight used
- Surface not level
- Movement during calibration
- Low batteries
- Scale malfunction
Solutions:
1. Check you're using correct weight
2. Move to more stable surface
3. Replace batteries
4. Retry in calmer environment
5. Try again from beginning
Scale Won't Enter Calibration Mode
Try:
- Different button combinations
- Consulting manual
- Turning off, waiting, trying again
- Replacing batteries
- Looking for hidden calibration button
Calibration Succeeds But Still Inaccurate
Possible issues:
- Calibration weight itself is inaccurate
- Scale has hardware damage
- Environmental interference
Solutions:
- Try different calibration weight
- Verify weight with another scale
- Test in different location
- Contact manufacturer
Display Shows Wrong Required Weight
Normal variation:
Different models require different calibration weights. Use what YOUR scale displays, not what seems standard.
Calibration for Different Scale Types
Pocket Scales (0.1g)
Typical procedure:
- 100g or 200g calibration
- Simple CAL button process
- Takes 1-2 minutes
Milligram Scales (0.001g)
More sensitive process:
- Usually 10g or 20g calibration
- Requires windshield closed
- Extremely stable surface needed
- More prone to environmental effects
- May need multiple calibrations
Kitchen Scales
Often auto-calibrating:
- Many don't have manual calibration
- Reset to factory through menu
- Less precise than pocket/milligram scales
Maintaining Calibration
Best Practices
Protect your calibration:
- Store scale properly (case if included)
- Avoid extreme temperatures
- Don't drop or jar scale
- Keep away from magnets
- Handle gently
Regular checks:
- Weekly: Verify with known weight
- Monthly: Full recalibration
- After any incident: Recalibrate
Environmental Factors
Affect accuracy:
- Temperature changes
- Humidity
- Altitude changes
- Air currents
- Vibrations
When accuracy matters most:
Calibrate in the same environment where you'll be weighing.

Summary
Calibration is simple but essential:
1. Prepare - Stable surface, warmed up scale
2. Enter mode - Usually hold CAL or MODE
3. Zero - Let scale establish baseline
4. Weigh - Place exact required weight
5. Confirm - Wait for PASS indication
6. Verify - Test with known weights
Regular calibration ensures your scale stays accurate. A few minutes monthly prevents measurement problems.

Frequently Asked Questions
定期使用、在降級後、顯著溫度變化或讀數不準確時每月校準一次。 新秤應在首次使用前進行校準。
