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.
• Differential Pressure Measurement: 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. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

4.1. പവർ ഓൺ/ഓഫ്

• To power on the EM720, press the പവർ button (typically marked with a circle and vertical line symbol).
• പവർ ഓഫ് ചെയ്യുന്നതിന്, അമർത്തിപ്പിടിക്കുക പവർ 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.

• അമർത്തുക 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.

• അമർത്തുക യൂണിറ്റുകൾ 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

• ഹോൾഡ്: അമർത്തുക പിടിക്കുക ഡിസ്പ്ലേയിൽ നിലവിലെ റീഡിംഗ് ഫ്രീസ് ചെയ്യാൻ ബട്ടൺ അമർത്തുക. റിലീസ് ചെയ്യാൻ വീണ്ടും അമർത്തുക.
• MIN/MAX/AVG: അമർത്തുക 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. താപനില അളക്കൽ

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

5. പരിപാലനം

5.1. വൃത്തിയാക്കൽ

• Wipe the instrument's exterior with a damp തുണിയും മൃദുവായ ഡിറ്റർജന്റും. അബ്രാസീവ് ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്.
• Ensure no moisture enters the pressure ports or other openings.

5.2. സംഭരണം

• Store the EM720SPKIT in its soft carrying case when not in use to protect it from dust, dirt, and physical damage.
• നേരിട്ടുള്ള സൂര്യപ്രകാശത്തിൽ നിന്നും തീവ്രമായ താപനിലയിൽ നിന്നും അകന്ന് തണുത്തതും വരണ്ടതുമായ സ്ഥലത്ത് സൂക്ഷിക്കുക.
• Remove batteries if storing for extended periods to prevent battery leakage and potential damage to the instrument.

5.3. കാലിബ്രേഷൻ

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.
