1. セットアップ

1.1 開梱と検査

Carefully remove the analytical balance from its packaging. Inspect all components for any signs of damage during transit. Ensure all accessories, such as the weighing pan, draft shield components, and power adapter, are present.

1.2 配置

Place the balance on a stable, level, and vibration-free surface. Avoid locations near air currents (e.g., air conditioning vents, open windows), direct sunlight, or heat sources, as these can affect measurement accuracy.

1.3 バランスの均衡

Use the adjustable feet at the base of the balance and the built-in spirit level (usually located near the display) to ensure the balance is perfectly level. Adjust the feet until the air bubble in the spirit level is centered.

1.4 組み立て

Assemble the draft shield components according to the diagrams provided with your balance. Carefully place the weighing pan onto the pan support. Ensure all parts are clean and properly seated.

1.5電源接続

Connect the power adapter to the balance's power input port and then plug it into a suitable electrical outlet. Allow the balance to warm up for at least 30 minutes after connecting power before performing any measurements or calibration. This ensures thermal stability for accurate readings.

2. 操作手順

2.1 電源のオン/オフ

• 電源を入れるには： ON ボタンを押します。ディスプレイにセルフテストシーケンスが表示され、0.0000gで安定します。
• 電源を切るには： オフ ディスプレイが消えるまでボタンを押し続けます。

2.2 外部キャリブレーション

Regular external calibration is crucial for maintaining accuracy. Refer to your balance's specific calibration procedure, typically involving a certified external calibration weight.

1. 天秤が水平であり、温まっていることを確認します。
2. Clear the weighing pan.
3. を押す カル button (or follow the menu prompts for calibration).
4. The display will prompt you to place the specified calibration weight (e.g., 200g) on the pan.
5. Carefully place the calibration weight on the center of the pan.
6. Wait for the balance to stabilize and complete the calibration process.
7. The display will indicate successful calibration, then prompt you to remove the weight.
8. Remove the weight. The balance should return to 0.0000g.

2.3 基本的な計量手順

1. Ensure the balance is level, warmed up, and calibrated.
2. を押す 風袋 button to zero the display if it's not already at 0.0000g.
3. If using a container, place the empty container on the weighing pan. Wait for the reading to stabilize, then press the 風袋 button again to zero the display (this subtracts the container's weight).
4. 慎重にsを配置しますample to be weighed onto the center of the weighing pan (or into the tared container).
5. Wait for the reading to stabilize. The displayed value is the net weight of your sampル。
6. Record the measurement.
7. を削除しますample and container.

2.4ユニットの選択

Your balance may support multiple weighing units (e.g., grams, milligrams, carats). Consult your balance's specific instructions for changing units, typically done via a ユニット or モード ボタン。

3. メンテナンス

3.1 クリーニング

• 清掃する前に必ず天びんを電源から外してください。
• 柔らかく糸くずの出ない布を使用してください。ampened with a mild detergent solution or isopropyl alcohol to clean the exterior surfaces, weighing pan, and draft shield.
• 研磨剤入りの洗剤、溶剤、または刺激の強い化学薬品は使用しないでください。
• 天秤のハウジングや表示領域に液体が入らないようにしてください。
• The weighing pan and draft shield glass panels can often be removed for more thorough cleaning. Refer to your balance's specific instructions for removal and reassembly.

3.2 ストレージ

When not in use, keep the balance covered with a dust cover (if provided) to protect it from dust and debris. Store in a dry, temperature-controlled environment.

3.3 定期点検

Periodically check the balance's level and perform external calibration to ensure continued accuracy, especially if the balance has been moved or subjected to environmental changes.
