6. Betjeningsvejledning
6.1 Grundlæggende opladning
Once batteries are inserted, the charger will automatically detect their type and initiate charging. The LCD will display real-time information for each channel.
6.2 Forståelse af LCD-skærmen
The LCD screen provides detailed information for each of the four channels:
- Voltage (V): Nuværende batteri voltage.
- Nuværende (A): Real-time charging current.
- IR (mΩ): Internal Resistance of the battery.
- Cap (mAh/Wh): Accumulated charging capacity or energy.
- Batteritype: Indicates Li-ion or Ni-MH.
6.3 Changing Charging Current
Press the 'Curr.' button to cycle through available charging currents (0.25A, 0.5A, 1A, 2A, 3A). The charger can deliver a maximum of 3A to a single slot, 2A to two slots simultaneously, or 1A to all four slots.

6.4 Driftstilstande
Press the 'Mode' button to switch between the three operation modes:
- Opladningstilstand: Standard charging of batteries.
- Grading Mode: Tests the real capacity of batteries by fully charging, discharging, and then recharging them. The final charge capacity is displayed.
- Storing Mode: Charges or discharges Li-ion batteries to their optimal storage voltage (typically 3.7V-3.8V) to maximize lifespan when not in use.

6.6 LED-indikatorer
The charger features LED indicators for each channel:
- Grøn: Standby or fully charged.
- Rød: Opladning.
- Grey/Off: Power supply unconnected or error.
