4. セットアップ
- 電源接続: Connect the tester to a 5V DC power source using one of the two Type-C interfaces. An adapter and cable are typically included.
- 電池の挿入: Insert flat-top 18650 batteries into the designated battery holders (3, 4, 5, 6). Ensure correct polarity (+ and -). The tester supports flat-top 18650 batteries.
- 安定: After installing a battery, allow a few seconds for the voltage and internal resistance readings on the display to stabilize before proceeding with tests.
5. 操作手順
The tester allows for independent operation of its four channels.

図4: Display and control buttons. This image provides a detailed view of the tester's screen and the four control buttons located below it, used for navigation and operation.
5.1. Basic Navigation and Channel Selection
- 使用 Channel /CHN Key (16) to switch between the four independent channels (CHN 1 to CHN 4).
- の Menu /M Key (13) is used to enter or exit menu settings.
- の Adjust /S Key (14) is used to change values or select options within a menu.
- の Start/Stop /R/S Button (15) initiates or terminates a test cycle.
5.2. Automatic Charge and Discharge Cycles
The tester supports fully automatic charging and discharging cycles (1-9 cycles adjustable in auto mode).
- 希望のチャンネルを選択するには、 Channel /CHN Key.
- を押す Menu /M Key モード選択に入ります。
- 使用 Adjust /S Key to select 'AUTO' mode.
- Adjust the number of cycles (LOOP: 1-9) using the Adjust /S Key 必要であれば。
- を押す Start/Stop /R/S Button to begin the automatic cycle. The charging process automatically stops when the battery is full.
5.3. Internal Resistance Measurement
The device utilizes the DC two-wire method to provide reference internal resistance values.
- For the most accurate reading, measure internal resistance when the battery is fully charged.
- The internal resistance value is displayed as 'mR' on the screen (5).
5.4. Setting Stop Discharge Voltage
You can choose from 11 stop-discharge voltage levels (2.5V to 3.5V).
- 目的のチャネルを選択します。
- Enter the menu using the Menu /M Key.
- Navigate to the 'STOP' voltage設定。
- 使用 Adjust /S Key to select the desired stop discharge voltage (2.5V, 2.6V, ..., 3.5V).
- 設定を確認してメニューを終了します。
5.5. 重要な使用上の注意
- Discharge current is fixed at a maximum of approximately 1A (non-adjustable, non-constant current).
- 充電voltage is fixed at 4.2V.
- This tester is 互換性がない with LiFePO4 batteries.
6. 安全情報
The device incorporates several safety features to ensure safe operation:
- 過熱保護: The integrated radiator fan (11) and internal sensors help prevent the device from overheating during operation.
- 自動電源オフ: Settings are automatically saved in case of power loss.
- Charge Cutoff: Automatic charge cutoff prevents overcharging of batteries.
- 排出停止: Configurable stop discharge voltage prevents over-discharging.
Always ensure correct battery polarity when inserting batteries to prevent damage to the device or batteries.
7. メンテナンス
- デバイスを清潔に保ち、ほこり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。
- Avoid exposing the tester to moisture or extreme temperatures.
- Ensure the cooling fan (11) is not obstructed to maintain proper airflow.
- 使用しないときは、デバイスを乾燥した涼しい場所に保管してください。
8。 トラブルシューティング
- Internal Resistance Readings Appear High at Low Voltages: If internal resistance readings seem unusually high, reinstall the battery. This can often provide a more accurate measurement.
- デバイスの電源が入っていない: Ensure the Type-C power cable is securely connected to a functional 5V DC power source. Try a different cable or adapter if necessary.
- バッテリーが検出されません: Verify that the battery is correctly inserted with the correct polarity and that it is a compatible 18650 flat-top lithium battery.
