3. Орнотуу жана Батареяны орнотуу
3.1 Батареяны орнотуу:
- Locate the battery compartment on the back of the manometer.
- Use the included small screwdriver to open the battery compartment cover.
- Туура полярдуулукту (+/-) камсыз кылып, эки 1.5V AAA батарейкасын салыңыз.
- Батарея уясынын капкагын ордуна коюңуз жана аны бурама менен бекитиңиз.
3.2 Connecting Pressure Hoses:
The AP-189A features dual ports for differential pressure measurement. Connect the pressure hoses to the (+) and (-) ports as required for your application. The (+) port measures positive pressure, and the (-) port measures negative pressure relative to the other port.
4. Иштөө нускамалары
4.1 Күйгүзүү/өчүрүү:
басыңыз Кубат баскычы (ⓘ) to turn the manometer on. Press and hold the same button to turn it off.
4.2 Unit Selection:
басыңыз UNIT button to cycle through the 11 available pressure units: psi, kPa, Kgfcm², ozin², Bar, mbar, inHg, mmHg, inH₂O, ftH₂O, cmH₂O. The selected unit will be displayed on the LCD.
4.3 Data Hold Function:
басыңыз БЕРҮҮ Учурдагы көрсөткүчтү дисплейде тоңдуруу үчүн баскычты басыңыз. Кармоо баскычын коё берип, түз көрсөткүчтөрдү улантуу үчүн аны кайра басыңыз.
4.4 Zero Setting:
To ensure accurate differential pressure measurements, it is crucial to zero the gauge before use. Ensure both pressure ports are open to atmospheric pressure or connected to the same pressure source before zeroing.
- First, briefly press the БЕРҮҮ баскычы.
- Андан кийин, басып, кармап туруңуз БЕРҮҮ button for more than 5 seconds. The display will show a "---" symbol, indicating successful zeroing.
Figure 5: Zero Setting procedure.
4.5 MAX/MIN/AVG/DIF Functions:
басыңыз REC button to enter data recording mode. Subsequent presses will cycle through MAX (maximum), MIN (minimum), and AVG (average) values recorded during the session. The DIF button displays the differential pressure.
4.6 Арткы жарык:
басыңыз Арткы жарык баскычы (🔆) to illuminate the LCD for better visibility in low-light conditions. Press again to turn off the backlight.
