1. Power supply battery compartment: Used to power the device itself.
2. Blue and red indicator light: Indicates charging status of the power supply battery. This does not relate to the test channels.
3. Type-C 5V power supply interface: Primary power input for the device.
4. ON/OFF/Menu button: Powers the device on/off and accesses menu options.
5. 調整ボタン： Cycles through different test modes.
6. スタート/ストップボタン: Initiates or terminates a test cycle.
7. Test ② Type-C external discharge interface: An alternative interface for testing batteries that do not fit the 18650 holder.
8. Test ① charging and discharging 18650 battery compartment: The primary slot for testing 18650 batteries.
9. 1.77 inch display screen: Shows real-time test data and settings.
10. 10W8ΩJ discharge cement resistance ×2: Resistors used for discharging batteries during tests.

重要な注意: Despite some product descriptions, user feedback indicates this device functions as a single-channel tester. The left battery slot (1) is primarily for powering the device, and the right slot (8) is the main test channel. The Type-C external discharge interface (7) can also be used for testing, but not simultaneously with slot (8).

3.2ディスプレイインターフェース

The 1.77-inch display provides comprehensive real-time information during testing:

2. Real Time Current: Current flowing during charge or discharge.
3. Real Time Power: Instantaneous power (Voltage × Current).
4. 累積容量: Total capacity measured in mAh.
5. Accumulated Energy: Total energy measured in mWh.
6. ステータスインジケーター: Shows the current state (e.g., STA:STOP, STA:CHG, STA:DIS).
7. 勤務パターン: Indicates the selected mode (e.g., MODE:AUTO, MODE:CHG, MODE:DIS).
8. Stop Discharge Voltage: セットボリュームtage at which discharge will cease.
9. サイクル数： Number of charge/discharge cycles completed in Auto mode.
10. Battery Internal Resistance: Measured internal resistance in mR.
11. 累積時間: Total duration of the current test cycle.

4. セットアップ

4.1 デバイスへの電源供給

The tester can be powered in two ways:

• Via Type-C: Connect a 5V Type-C power adapter and cable (included) to the Type-C 5V power supply interface (3).
• Via Power Supply Battery: Insert an 18650 battery into the Power supply battery compartment (1) on the left side of the device. This battery will power the tester's internal circuitry.

4.2 Battery Installation for Testing

To test an 18650 battery:

• Insert the flat-top 18650 battery into the Test ① charging and discharging 18650 battery compartment (8) on the right side of the device, ensuring correct polarity.
• Alternatively, for batteries that do not fit the 18650 holder, connect them to the Test ② Type-C external discharge interface (7) using appropriate cables.

5. 操作手順

5.1 電源オン/オフ

• を押す ON/OFF/Menu button (4) to power on the device.
• を押し続けます ON/OFF/Menu button (4) to power off the device.

5.2 Selecting Test Mode

を押す 調整する button (5) to cycle through the available test modes:

• 自動モード： Performs a full charge, then discharges to measure capacity, and finally recharges the battery. This cycle can be adjusted from 1 to 9 loops.
• チャージモード: Charges the battery to 4.2V.
• 放電モード: Discharges the battery to the selected stop-discharge voltage.

5.3 Setting Stop-Discharge Voltage

In DISCHARGE or AUTO mode, you can select from 11 stop-discharge voltage levels ranging from 2.5V to 3.5V. Use the 調整する button (5) to change this setting before starting the test.

5.4 Starting and Stopping a Test

• を押す 開始/停止 button (6) to begin the selected test mode.
• を押す 開始/停止 button (6) again to pause or stop an ongoing test.
• When a test is stopped, a long press of the 開始/停止 button (6) will reset the onscreen data.

5.5 内部抵抗測定

The device utilizes the DC two-wire method to provide a reference internal resistance value. For the most accurate reading, measure the internal resistance when the battery is fully charged.

6. メンテナンス

• デバイスを清潔に保ち、ほこりやゴミを取り除いてください。清掃には柔らかく乾いた布を使用してください。
• Ensure proper ventilation during operation, especially during discharge cycles, as the device can generate heat. Do not obstruct the discharge resistors.
• テスターは直射日光や極端な温度を避け、乾燥した環境に保管してください。

7。 トラブルシューティング

• デバイスの電源が入らない: Verify that the Type-C power adapter is correctly connected and supplying 5V, or ensure the power supply battery in slot (1) is charged and properly inserted.
• Test does not start: Check that the battery is correctly inserted into the test compartment (8) with the correct polarity. Ensure a test mode (AUTO, CHARGE, DISCHARGE) has been selected.
• Inaccurate internal resistance readings: Reinstall the battery and ensure it is fully charged for the most accurate internal resistance measurement. Readings can be higher at low battery voltages。
• デバイスが熱く感じる: This is normal during discharge cycles due to the resistive load. The device has built-in overheating protection. Ensure good airflow around the device.
