6. Mantemento
- Limpeza: Wipe the unit and probe with a soft, damp pano. Non use produtos de limpeza ou disolventes abrasivos.
- Substitución da batería: Replace batteries when the low battery indicator appears on the display. Ensure proper battery type and polarity.
- Almacenamento: When not in use for extended periods, remove the batteries and store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Recalibración: Due to the nature of humidity sensors, periodic recalibration is recommended to maintain accuracy. Refer to the NIST-Traceable certificate for recommended recalibration intervals.
7 Solución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| Sen pantalla ou pantalla tenue | Dead or weak batteries; incorrect battery installation. | Substitúe as pilas por outras novas, garantindo a polaridade correcta. |
| Lecturas inexactas | Sensor contamination; need for recalibration; probe not properly connected. | Clean the probe gently; perform recalibration; ensure probe is securely connected. |
| RS-232 communication failure | Incorrect cable; software settings mismatch; port issue. | Verify cable connection and type; check software communication settings (baud rate, parity); try a different USB/serial port. |
