6. Návod k obsluze
6.1. Socket Wiring Test
Once plugged into a 230V socket, the device's LEDs will illuminate to indicate the wiring status. Refer to the legend on the device for specific interpretations. Common indications include:
- Správné zapojení: All LEDs illuminate in a specific pattern (refer to device markings).
- Missing Earth: A specific LED pattern indicates the absence of an earth connection.
- Reversed Phase/Neutral: Another pattern indicates incorrect phase and neutral connections.
- Missing Phase or Neutral: Specific LEDs will not illuminate.
Always consult the detailed legend on the device itself for precise interpretation of the LED patterns for various fault conditions.
6.2. Zkouška proudového chrániče (RCD)
The RCD test function verifies the proper operation of the residual current device protecting the circuit.
- Plug the Testavit Schuki 2K into the socket.
- Rotate the RCD Current Selector Dial (S1) to the desired nominal residual current setting (e.g., 30 mA).
- Press and hold the red RCD Test Button (T).
- Observe the RCD (circuit breaker) in your electrical panel. A functional RCD should trip (switch off) within a short period (typically less than 200ms).
- If the RCD trips, it indicates that the RCD is functioning correctly at the selected current. Reset the RCD at your electrical panel.
- If the RCD does not trip, it indicates a potential fault with the RCD or the wiring. Do not use the circuit and consult a qualified electrician.
- After testing, return the RCD Current Selector Dial (S1) to the "OFF" position.

8. Řešení problémů
If you encounter issues with your Testavit Schuki 2K, consider the following:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Po zapojení se nerozsvítí žádné LED diody. | No power to the socket; device is faulty. | Check the circuit breaker for the socket. Test the socket with another known working appliance. If still no lights, the device may be faulty. |
| Incorrect wiring indicated (e.g., missing earth). | Actual wiring fault in the socket. | Do not use the socket. Consult a qualified electrician to inspect and repair the wiring. |
| Proudový chránič se během testu nevypne. | Faulty RCD; incorrect RCD current setting; no earth connection. | Ensure the RCD current selector is not on "OFF". Verify socket wiring (especially earth). If the RCD still doesn't trip, it may be faulty and requires inspection by a qualified electrician. |
| Device appears damaged. | Fyzické poškození. | Discontinue use immediately. Do not attempt to repair. Contact Testboy customer support. |
