3.1. Device Components

Figure 3: Key components of the Testavit Schuki 6.
- LCD Display: Shows voltage, leakage current, and wiring status.
- Power/Hold Button: Turns the device on/off and holds the current reading.
- RCD Test Button: Initiates the Residual Current Device (RCD) test.
4. Setup
The Testboy Testavit Schuki 6 is ready for use immediately after inserting the batteries. It requires 2x 1.5V AAA batteries (included).
4.1. Battery Installation
- Locate the battery compartment cover on the back of the device.
- Open the cover and insert two 1.5V AAA batteries, observing the correct polarity (+/-).
- Close the battery compartment cover securely.
The device will automatically power on when plugged into a live socket, or can be manually powered on using the Power/Hold button.
5. Operation
5.1. Socket Wiring Check
- Plug the Testboy Testavit Schuki 6 into the socket you wish to test.
- The LCD display will immediately show the voltage and the wiring status.
- Refer to the wiring interpretation table (Figure 4) to understand the displayed status.

Figure 4: Wiring Interpretation Table.
Interpretation of Display:
- L / N / E - CORRECT: All wiring is correct (Live, Neutral, Earth).
- E - OPEN: Earth wire is open or missing.
- N - OPEN: Neutral wire is open or missing.
- ---: Live wire is open or missing.
- L / E - REVERSE: Live and Earth wires are reversed.
- L / N - REVERSE: Live and Neutral wires are reversed.

5.2. RCD (FI) Test Function
The RCD test function checks the functionality of Residual Current Devices (FI/RCD circuit breakers) by simulating a fault current.
- Plug the Testboy Testavit Schuki 6 into the socket protected by the RCD you wish to test.
- Ensure no critical equipment is connected to the circuit, as the RCD test will trip the circuit breaker.
- Press the RCD Test Button (3).
- The RCD should trip within the specified time (10-1000 ms).
- If the RCD does not trip, it indicates a potential fault with the RCD or the electrical installation. Consult a qualified electrician immediately.
- After the test, reset the RCD at your electrical panel.
