1. Output and controls - Output voltage: 110-2600 V DC - Voltage adjustment: turn the voltage knob to the right to increase voltage and to the left to decrease voltage - Output current: 0.25-3.4 mA - Current adjustment: turn the current knob to the right to increase current and to the left to decrease current 2. Portable size - Compact tool for daily use - Easy to carry in a tool bag and does not take up much storage space 3. Testing guidance - When testing MOS transistors and Zenera diodes, set current to a minimum of 0.25 mA and to a maximum of 3.4 mA 4. Wide range of uses - Widely used to test MOS, transistors, IGBT, diodes, Zenera diodes - Testing the maximum LED bridge - Checking the voltage of capacitor and varistors - Useful for LED lighting and lamp plates 5. Use scenarios - Electronics repair or service: test MOS transistors and Zenera diodes to diagnose faulty components in repair projects - LED lighting maintenance: verify LED drivers, LED modules, and lamp boards to ensure proper operation - PCB and component checks: measure capacitor and varistor voltages during routine inspections or testing procedures
