安全情報
Always prioritize safety when working with vehicle batteries. Please read and understand the following safety precautions:
- Ensure the vehicle engine is turned off before connecting or disconnecting the tester, unless performing an alternator test as instructed.
- Wear appropriate personal protective equipment, including safety glasses and gloves, to protect against battery acid and electrical hazards.
- Avoid contact with battery terminals and cables while the engine is running or the battery is connected.
- Keep the tester away from water, oil, and other liquids.
- The BM310 features a reverse protection function to prevent damage from incorrect polarity connection. However, always double-check connections to ensure proper operation and safety.
- テスターを分解したり改造したりしないでください。修理は必ず資格のある担当者にご依頼ください。

操作手順
The BM310 provides two primary functions: Battery State Check and Alternator State Check.
1. Battery State Check
With the tester connected to the 12V battery and the engine off, observe the "Battery State" LEDs:
- Full (Green LED): バッテリーが完全に充電されていることを示します。
- Middle (Orange LED): Indicates the battery is moderately charged.
- Low (Red LED): Indicates the battery charge is low and may require charging.
- Check before Charge (Green LED): If this LED is lit, it suggests the battery could be charged. If the voltage drops to 10V, the battery may be damaged and cannot be charged.

2. Alternator State Check
To check the alternator's performance:
- Ensure the tester is correctly connected to the battery.
- 車両エンジンを始動します。
- Accelerate the engine to approximately 2000 回転.
- Observe the "Alternator State" LEDs:
- Good (Green LED): Indicates the charging circuit is functioning correctly.
- 障害（赤色LED）： Indicates a charging system error. If this light is lit, the alternator voltage may be too high, which could damage your battery.

メンテナンス
To ensure the longevity and accurate performance of your EDIAG BM310 tester, follow these simple maintenance guidelines:
- クリーニング： 使用後は毎回、柔らかく乾いた布で拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。
- ストレージ： テスターは直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。使用しないときは、元の包装または保護ケースに入れて保管してください。
- ケーブルのお手入れ: ケーブルとclを検査しますamp定期的に摩耗、ほつれ、損傷がないか確認してください。必要に応じて交換してください。
- ドロップを避ける： While built with durable ABS material, avoid dropping the device to prevent internal damage.
トラブルシューティング
If you encounter issues with your EDIAG BM310, refer to the following common problems and solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| No LEDs light up when connected. | Incorrect connection; Battery completely dead; Faulty clamps/ケーブル。 | 極性（+と+、-と-）が正しいことを確認してください。電池の容量を確認してください。tage with a multimeter. Inspect clamps and cables for damage. |
| "Fault" LED for Alternator State is lit. | Alternator charging system error; Over-voltage. | Consult a professional mechanic to diagnose the alternator or charging system. |
| "Low" LED for Battery State is lit. | バッテリーが放電しました。 | Charge the battery. If the "Check before Charge" LED does not light up after charging, the battery may be damaged. |
