5. 操作手順
5.1. 充電モード
The charger defaults to charging mode when batteries are inserted. The LCD screen will display real-time information for each channel.
5.2. 充電電流の調整
を押す "Curr" button to switch between available charging currents (2A, 1A, 0.5A). The selected current will be applied to the corresponding channel.

5.3. Switching Display Content
In charging mode, press the "モード" button to switch the display content between channels (CH1, CH2, CH3, CH4) or to view different parameters like charging capacity (Cap) or internal resistance (IR).
5.4. Grad Mode (Capacity Measurement)
To enter Grad mode for capacity measurement, long-press the "モード" button. This mode charges the battery to full, then discharges it to measure its actual capacity, and finally recharges it to full. This process helps assess the battery's true health.
5.5. ストアモード
長押しすると "モード" button again to cycle to Store mode. This mode is used to charge or discharge batteries to an optimal storage voltage, preserving their lifespan.
5.6. Automatic Energy Saving
When no batteries are inserted or no operations are performed within about 60 seconds, the screen will go dim to save energy. If a battery is inserted or any button is pressed, the screen will reactivate.
