8. Solución de problemas
If you encounter issues with your UNI-T UT202R, refer to the following common troubleshooting steps:
- Sin pantalla/Pantalla débil: Compruebe la instalación de las pilas y sustitúyalas si es necesario. Asegúrese de que el medidor esté encendido.
- Lecturas incorrectas:
- Ensure the correct measurement function is selected.
- Verify test lead connections are secure and undamaged.
- Check for proper contact with the circuit or component.
- Para mediciones de corriente, asegúrese de que solo un conductor esté dentro del clamp mandíbula.
- Visualización "OL" (Sobrecarga): El valor medido excede el rango seleccionado. Cambie a un rango superior o asegúrese de que la medición esté dentro de las capacidades del medidor.
- No hay pitido de continuidad: Check if the circuit is truly continuous or if the resistance is too high for the continuity threshold.
Si los problemas persisten, comuníquese con el servicio de atención al cliente de UNI-T o con un técnico calificado.
