3.1. 배터리 설치

1. Locate the battery compartment cover on the rear of the EM720 manometer.
2. 덮개를 밀거나 돌려서 여세요.
3. Insert the included batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
4. 배터리함 덮개를 단단히 다시 닫으십시오.

3.2. Connecting Probes and Tubing

The EM720SPKIT includes various accessories for different measurement scenarios:

• Static Pressure Measurement: Connect one static pressure probe to an input port (P1 or P2) on the top of the manometer using the pressure tubing.
• 차압 측정: Connect tubing from two different pressure points to both input ports (P1 and P2). Ensure P1 is connected to the higher pressure side and P2 to the lower pressure side for positive differential readings.
• Using Fittings: Utilize the stepped T fittings and step connectors as needed to adapt to different port sizes or to create a manifold for specific test setups.

Always ensure connections are snug to prevent pressure leaks, which can affect measurement accuracy.

4. 사용 설명서

4.1. 전원 켜기/끄기

• To power on the EM720, press the 힘 버튼(일반적으로 원과 세로선 기호로 표시됨).
• 전원을 끄려면 힘 button until the display turns off. The instrument may also have an auto-power off feature to conserve battery life.

4.2. Zeroing the Manometer

Before taking measurements, it is crucial to zero the manometer to ensure accuracy. Disconnect all pressure tubing from the input ports (or ensure both ports are open to ambient air) and allow the instrument to stabilize.

• 를 누르세요 DIF ZERO button. The display should show a reading close to zero.
• If the reading does not zero, ensure no pressure is applied to the ports and repeat the zeroing process.

4.3. 측정 단위 선택

The EM720 supports multiple pressure units.

• 를 누르세요 단위 button to cycle through available pressure units (e.g., in WC, Pa, kPa, psi, mbar, mmHg).
• Select the unit appropriate for your application.

4.4. Data Hold, Min/Max/Avg Functions

• 보류: 를 누르세요 잡고 있다 버튼을 누르면 디스플레이에 현재 측정값이 고정됩니다. 다시 누르면 고정이 해제됩니다.
• MIN/MAX/AVG: 를 누르세요 REC MAX/MIN button to enter recording mode. Subsequent presses will cycle through Minimum, Maximum, and Average readings captured since entering the mode. Press and hold to exit recording mode.

4.5. 온도 측정

The EM720 also provides ambient temperature measurement, displayed alongside pressure readings. This feature aids in understanding environmental conditions that may affect pressure readings.

5. 유지관리

5.1. 청소

• Wipe the instrument's exterior with a damp 천과 중성세제. 연마성 세척제나 솔벤트를 사용하지 마십시오.
• Ensure no moisture enters the pressure ports or other openings.

5.2. 보관

• Store the EM720SPKIT in its soft carrying case when not in use to protect it from dust, dirt, and physical damage.
• 직사광선 및 극한의 온도를 피하고 서늘하고 건조한 곳에 보관하십시오.
• Remove batteries if storing for extended periods to prevent battery leakage and potential damage to the instrument.

5.3. 교정

For continued accuracy, it is recommended to have the EM720 manometer calibrated periodically by a qualified service center. Refer to UEi Test Instruments' official website or contact customer support for calibration services and recommended intervals.
