4. Тохиргоо

4.1 Батерей суурилуулах

1. Locate the battery compartment cover on the back of the manometer.
2. Бүрхүүлийг ав.
3. Insert the supplied 9V alkaline battery, ensuring correct polarity.
4. Зайны тасалгааны тагийг найдвартай солино.

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. Ашиглалтын заавар

5.1 Асаах/унтраах

• дээр дарна уу ON/OFF товчийг дарж төхөөрөмжийг асаана.
• дээр дарна уу ON/OFF button again to power off the device.

5.2 Auto Zero Function

Хэмжилт хийхээс өмнө нарийвчлалыг хангахын тулд багажийг тэг болгох нь чухал юм.

1. Ensure both pressure ports are open to atmospheric pressure (disconnected from any pressure source).
2. дээр дарна уу ТЭГ 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.

• дээр дарна уу НЭГЖ button to cycle through available pressure units (e.g., in. w.c., kPa).
• Хэмжилтийн хүссэн нэгжийг сонгоно уу.

5.4 Хэмжилт хийх

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. Засвар үйлчилгээ

6.1 Цэвэрлэгээ

Wipe the exterior of the manometer with a soft, damp даавуу. Зүлгүүрийн цэвэрлэгч эсвэл уусгагч хэрэглэж болохгүй, учир нь эдгээр нь скрабыг гэмтээж болзошгүй.asing эсвэл дэлгэц.

6.2 Батерейг солих

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 Хадгалалт

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.
