3. Daħħal żewġ batteriji AAA, waqt li tiżgura l-polarità korretta (+/-).
4. Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha bil-kamin.

3.2 Konnessjoni tal-Pajpijiet

1. Identify the positive (+) and negative (-) pressure ports at the top of the device.
2. Connect the soft hoses (1/8 inch / 3.18 mm quick connectors) to the desired ports based on your measurement requirements.
3. Ensure the connections are secure to prevent leaks.

4. Istruzzjonijiet Operattivi

4.1 Power On/Off

• Agħfas il- ON/OFF buttuna biex tixgħel l-apparat.
• Biex titfi, agħfas u żomm il-buttuna ON/OFF buttuna sakemm il-wiri jintefa.
• The device will automatically shut down after approximately 25 minutes of inactivity.

4.2 Għażla ta' Unità

• Agħfas il- UNITÀ button to cycle through the 11 available pressure units (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, KPa, mbar, bar, psi, Kgcm², ozin²).
• Select the appropriate unit for your measurement.

4.3 Funzjoni tad-Dawl ta' Wara

• Agħfas il- Dawl ta' wara button (light bulb icon) to turn the LCD backlight on or off. This improves visibility in low-light conditions.

4.4 Funzjoni ta' Żamma tad-Data

• Waqt il-kejl, agħfas il-buttuna ŻOMM button to freeze the current reading on the display.
• Agħfas ŻOMM again to release the data hold and resume live measurement.

4.5 Differential (DIF) Mode

• Agħfas il- DIF button to activate differential pressure measurement. This mode displays the difference between the two input pressures.
• Agħfas DIF again to exit differential mode.

4.6 Record (REC) Mode

• Agħfas il- REC button to enter recording mode. The device will start recording maximum (MAX), minimum (MIN), and average (AVG) pressure values.
• While in REC mode, you can cycle through MAX, MIN, and AVG readings by pressing the REC buttuna ripetutament.
• To exit REC mode, press and hold the REC buttuna.

5. Manutenzjoni

Proper maintenance ensures the longevity and accuracy of your INFURIDER YF-189A differential pressure gauge.

• Tindif: Imsaħ l-apparat b'ċarruta ratba u niexfa. Tużax prodotti tat-tindif jew solventi li joborxu.
• Ħażna: When not in use, store the device in the provided protective bag to shield the ports from dust and rust. Store in a cool, dry place away from direct sunlight and extreme temperatures.

6 Issolvi l-problemi

If you encounter issues with your INFURIDER YF-189A, refer to the following common problems and solutions:

• L-apparat ma jixgħelx:
  • Iċċekkja jekk il-batteriji humiex installati sew bil-polarità t-tajba.
  • Ibdel il-batteriji b'batteriji AAA ġodda.
• Display shows "ERR1" or "ERR2":
  • These error codes indicate that the measured pressure is outside the device's specified range (±6 Psi). Reduce the applied pressure or ensure the pressure is within the operational limits.
• Qari mhux preċiż:
  • Ensure hoses are securely connected and free from kinks or blockages.
  • Verify that the selected unit is appropriate for the measurement.
  • Ensure the device is operating within the specified temperature range (0~40℃).
• Id-dawl ta' wara mhux qed jaħdem:
  • Check battery level. Low batteries may affect backlight functionality.
