5. Instrucións de funcionamento

The SMSPN06 features a simplified control interface with three buttons: "SET", "++", and "--".

5.1. How to Adjust the Frequency

1. When powered on, the digital tube displays the current frequency. Press the "CONFIGURAR" button. The last decimal point on the display will flash, indicating that the setting mode has been entered.
2. Preme o "++" or "--" button to increase or decrease the frequency. Long-pressing these buttons will speed up the adjustment process.
3. After setting your desired frequency, press the "CONFIGURAR" button again to exit the setting mode and save the new parameters.

5.2. How to Save Parameters After Power Off

To ensure your frequency settings are retained even after the device is powered off, press and hold the "++" botón ata que a pantalla LED mostre "S-N". This indicates that the power-off save function is enabled.

5.3. How to Restore Factory Settings

• Default Restore: Normally, simply power the device off and then on again to restore default settings.
• If Power-Off Save is Enabled: If you have enabled the power-off save function, press and hold the "++" button until the LED displays "S-F". Then, power the device off and on again to restore factory settings.

5.4. How to Turn Off the Digital Tube Display

To turn off the digital tube display, press and hold the "--" button until the digital tube displays "S-P". The digital tube will automatically turn off after 10 seconds.

If the digital tube automatically turns off after 10 seconds, it means the energy-saving mode is active. To disable this, press and hold the "--" botón ata que "N-P" móstrase.

5.5. How to Verify the Output Waveform

To verify the output waveform of the device, use an oscilloscope to measure the "GND/SIN" port. You should observe a pure sine wave.

6. Mantemento

To ensure the longevity and optimal performance of your eletechsup SMSPN06, please follow these general maintenance guidelines:

• Manteña o dispositivo limpo e libre de po e residuos. Use un pano suave e seco para limpar.
• Evite expoñer o dispositivo a temperaturas extremas, humidade ou luz solar directa.
• Non deixe caer o dispositivo nin someta o dispositivo a fortes impactos.
• Garda o dispositivo nun lugar fresco e seco cando non estea en uso.
• Non intente desmontar nin reparar o dispositivo vostede mesmo, xa que isto anulará a garantía e podería causar danos.

7 Solución de problemas

This section addresses common questions and issues you might encounter with your SMSPN06 device.

Image: A visual representation of the Q&A section, providing quick answers to common operational queries regarding frequency adjustment, parameter saving, factory reset, and digital display control.

• Q: How to adjust the frequency?

  A: Press "SET" to enter setting mode (last decimal point flashes). Use "++" / "--" to adjust. Press "SET" again to save and exit.

• Q: Need to save parameters even after power off?

  A: Press and hold "++" until the LED displays "S-N" to enable power-off saving.

• P: Como restaurar a configuración de fábrica?

  A: Normally, power off and on again. If power-off save is enabled, press and hold "++" until "S-F" is displayed, then power off and on again.
• Q: How to turn off the digital tube?

  A: Press and hold "--" until "S-P" is displayed. The digital tube will turn off after 10 seconds.

• Q: Why does the digital tube automatically turn off after 10 seconds?

  A: This is due to the energy-saving mode. To disable it, press and hold "--" until "N-P" is displayed.
