4. Konfigurazioa

4.1 Bateriaren instalazioa

1. Locate the battery compartment cover on the back of the manometer.
2. Kendu estalkia.
3. Insert the supplied 9V alkaline battery, ensuring correct polarity.
4. Jarri bateriaren konpartimenduaren estalkia ongi.

4.2 Tubing Connection

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. Funtzionamendu-argibideak

5.1 Piztu/Itzaltzea

• Sakatu ON/OFF gailua pizteko botoia.
• Sakatu ON/OFF button again to power off the device.

5.2 Zero automatikoaren funtzioa

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. Sakatu ZERO 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.

• Sakatu UNITATEAK button to cycle through available pressure units (e.g., in. w.c., kPa).
• Hautatu nahi duzun neurketa-unitatea.

5.4 Neurketak hartzea

1. Egin Zero Automatiko funtzioa 5.2 atalean deskribatutako moduan.
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. Mantentzea

6.1 Garbiketa

Wipe the exterior of the manometer with a soft, damp oihal. Ez erabili garbitzaile edo disolbatzaile urratzailerik, hauek kalte egin baitezakete c-riasing edo pantaila.

6.2 Bateria ordezkatzea

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 Biltegiratzea
