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.
• Pengukuran Tekanan Pembezaan: 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. Arahan Operasi

4.1. Hidupkan/Mati Kuasa

• To power on the EM720, press the KUASA button (typically marked with a circle and vertical line symbol).
• Untuk mematikan, tekan dan tahan KUASA 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.

• Tekan ke 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. Memilih Unit Pengukuran

The EM720 supports multiple pressure units.

• Tekan ke UNIT 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

• DIBERI: Tekan ke TAHAN butang untuk membekukan bacaan semasa pada paparan. Tekan sekali lagi untuk melepaskan.
• MIN/MAX/AVG: Tekan ke 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. Pengukuran Suhu

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

5. Penyelenggaraan

5.1. Pembersihan

• Wipe the instrument's exterior with a damp kain dan detergen lembut. Jangan gunakan pembersih atau pelarut yang melelas.
• Ensure no moisture enters the pressure ports or other openings.

5.2. Penyimpanan

• Store the EM720SPKIT in its soft carrying case when not in use to protect it from dust, dirt, and physical damage.
• Simpan di tempat yang sejuk dan kering, jauh dari cahaya matahari langsung dan suhu yang melampau.
• Remove batteries if storing for extended periods to prevent battery leakage and potential damage to the instrument.

5.3. Penentukuran

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.
