3. Configuració

3.1. Instal·lació de la bateria

1. Locate the battery compartment cover on the rear of the EM720 manometer.
2. Obriu la tapa fent-la lliscar o desenroscant-la.
3. Insert the included batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
4. Col·loqueu la coberta del compartiment de la bateria amb seguretat.

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.
• Mesura de la pressió diferencial: 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. Instruccions de funcionament

4.1. Encendre/apagar

• To power on the EM720, press the PODER button (typically marked with a circle and vertical line symbol).
• Per apagar-lo, manteniu premut el botó PODER 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.

• Premeu el botó 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. Selecting Measurement Units

The EM720 supports multiple pressure units.

• Premeu el botó UNITATS 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

• MANTENIR: Premeu el botó MANTENIM per congelar la lectura actual a la pantalla. Premeu-la de nou per alliberar-la.
• MÍN/MÀX/MITJANA: Premeu el botó 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. Mesura de la temperatura

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

5. Manteniment

5.1. Neteja

• Wipe the instrument's exterior with a damp drap i detergent suau. No utilitzeu netejadors abrasius ni dissolvents.
• Ensure no moisture enters the pressure ports or other openings.

5.2. Emmagatzematge

• Store the EM720SPKIT in its soft carrying case when not in use to protect it from dust, dirt, and physical damage.
• Emmagatzemar en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
• Remove batteries if storing for extended periods to prevent battery leakage and potential damage to the instrument.

5.3. Calibració

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.
