4.1 Instalacija baterije

1. Locate the battery compartment cover on the back of the manometer.
2. Skinite poklopac.
3. Insert the supplied 9V alkaline battery, ensuring correct polarity.
4. Vratite sigurno poklopac odeljka za baterije.

4.2 Priključak cijevi

The manometer features two barbed connections for tubing. These connections accept 1/8" (3.18 mm) or 3/16" (4.76 mm) I.D. tubing.

1. For positive pressure, connect the tubing from the pressure source to the positive (+) port.
2. For negative pressure (vacuum), connect the tubing from the vacuum source to the negative (-) port.
3. For differential pressure, connect the higher pressure source to the positive (+) port and the lower pressure source to the negative (-) port.
4. Ensure tubing connections are snug to prevent leaks.

5. Uputstvo za upotrebu

5.1 Uključivanje/isključivanje

• Pritisnite ON/OFF dugme za uključivanje uređaja.
• Pritisnite ON/OFF ponovo pritisnite dugme da biste isključili uređaj.

5.2 Auto Zero Function

Before taking a measurement, it is crucial to zero the instrument for accuracy.

1. Ensure both pressure ports are open to atmospheric pressure (disconnected from any pressure source).
2. Pritisnite NULA button. The display will show '0.00' or a similar indication, confirming the zeroing process.

5.3 Pressure Unit Selection

The manometer allows selection between U.S. and metric pressure units.

• Pritisnite JEDINICE button to cycle through available pressure units (e.g., in. w.c., kPa).
• Odaberite željenu jedinicu za mjerenje.

5.4 Mjerenje

1. Perform the Auto Zero function as described in Section 5.2.
2. Connect the tubing to the appropriate pressure source(s) as described in Section 4.2.
3. The large LCD will display the pressure reading in the selected units.
4. The manometer can display positive, negative, or differential pressures.

6. Održavanje

6.1 Čišćenje

Wipe the exterior of the manometer with a soft, damp krpu. Ne koristite abrazivna sredstva za čišćenje ili rastvarače, jer mogu oštetiti casing ili prikaz.

6.2 Zamjena baterije

When the battery indicator appears on the display, replace the 9V alkaline battery following the steps in Section 4.1. A fresh battery provides up to 100 hours of operation.

6.3 Skladištenje

Store the manometer in a dry, cool place, away from direct sunlight and extreme temperatures. Disconnect tubing and remove the battery if storing for extended periods to prevent leakage.
