03FUNCTION

Testing without disassembly

The CA-300V automatically adapts output voltage according to the load connected. It identifies lamp beads and light bars instantly, eliminating manual configuration errors. By testing capacitance and diode voltage directly, the tool allows users to verify backlight performance without removing panels from their frames, saving time during repair or installation tasks.
