4. Instruccions de funcionament
4.1 Encès/Apagat
- Premeu el botó ON/OFF button (red power icon) to turn the device on.
- Manteniu premut el botó ON/OFF botó per apagar el dispositiu.
4.2 Calibració zero
Before each measurement, especially for differential pressure, it is recommended to perform a zero calibration to ensure accuracy.
- Ensure both pressure ports are open to atmospheric pressure or disconnected from any pressure source.
- Premeu llargament el botó MANTENIM button to clear any zero drift and calibrate the device to zero.
4.3 Selecció d'unitats
The manometer supports 12 different pressure units.
- Premeu el botó UNITATS button to cycle through the available pressure units (PSI, inHg, inH₂O, ftH₂O, kPa, mbar, Bar, kgcm², ozin², mmHg, cmH₂O, Pa).
4.4 Differential Pressure Measurement (P1-P2)
The device automatically displays the pressure difference between the two ports (P1-P2).
- Connect the higher pressure source to the (+) port and the lower pressure source to the (-) port for positive readings, or vice-versa.
- The display will show the real-time pressure difference.

6. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén | Bateria morta o instal·lada incorrectament | Comproveu la polaritat de la pila o substituïu-la per una pila nova de 9 V. |
| Inaccurate readings / Zero drift | Environmental factors or sensor drift | Perform one-button zero calibration by long pressing the HOLD button. Ensure ports are open to atmosphere during calibration. |
| Display shows "Err0" | Exceeds positive pressure range | The measured pressure is above the maximum positive range. Reduce pressure or use a device with a higher range. |
| Display shows "Err1" | Exceeds negative pressure range | The measured pressure is below the minimum negative range. Reduce vacuum or use a device with a wider negative range. |
| La llum de fons no funciona | Backlight off or low battery | Press the °C/°F button to toggle backlight. Check battery level and replace if low. |
| Auto-shutdown occurs too quickly | Normal operation (15 minutes inactivity) | This is a power-saving feature. The device will shut down after 15 minutes of no operation. |
