6. Instruccions de funcionament

The GOWENIC Shortkiller is designed for efficient short circuit detection on electronic motherboards. Always proceed with caution.

1. Prepara la placa base: Ensure the motherboard to be tested is clean, dry, and disconnected from any power source or battery.
2. Connectar a terra: Attach the black alligator clip of the test lead to a known ground point on the motherboard.
3. Ajust Voltage: Use the 'V+' and 'V-' buttons on the Shortkiller to set the desired output voltage. Start with a low voltage and gradually increase if necessary.
4. Probe Suspected Area: Carefully touch the red needle probe to the suspected shorted areas on the motherboard.
5. Observeu les lectures: Monitor the current (A) and voltage (V) displays. A sudden increase in current indicates a short circuit.
6. Locate Fault: The device will help locate the short circuit by causing the fault point to heat up or, in some cases, burn out the faulty component. Use thermal imaging or careful touch (with insulated tools) to pinpoint the exact location.
7. Desconnectar: Once the short is identified or repaired, power off the Shortkiller and disconnect the test leads from the motherboard.
