Battery Charging
- For charging, use only a USB power supply unit whose output voltage and minimum output current comply with the requirements in the "Technical data" section. Observe the operating manual of the USB power supply unit.
- Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the type plate of the power supply.
- Only charge the battery via the USB port at ambient temperatures between 0 °C and +40 °C. Charging outside the temperature range can damage the battery or increase the risk of fire.
Note: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before using your tool for the first time.
The battery charge indicator (11) shows the state of charge of the battery during operation:
LED | Capacity |
|---|---|
Continuous green light | 70–100 % |
Continuous yellow light | 30–70 % |
Continuous red light | 10–30 % |
Flashing red light | 0–10 % |
If the battery charge indicator (11) flashes red, the laser beams are switched off.
Charge the battery. To do this, connect the USB Type-C® port (12) to a USB power supply unit using a suitable USB cable (16). Connect the USB power supply unit to the mains supply. The measuring tool can continue to be operated during charging.
During the charging process, the battery charge indicator (11) shows the charging progress or errors:
LED | Meaning |
|---|---|
Flashing green light | Battery is being charged |
Continuous green light | Battery fully charged |
Flashing red light | Battery temperature outside the recommended temperature range; charging voltage or charging current is unsuitable |
Continuous red light | Battery defective or no battery inserted |
Remove the USB cable (16) after completing the charging process. Protect the USB Type-C® port (12) from dust and splashes.
Note: If required, you can also operate the measuring tool without the battery inserted, using only a connected USB power supply unit. Unplug the measuring tool from the mains after operation.
