2. Značilnosti izdelka

• Stable and Reliable Sensor: Utilizes a temperature-compensated pressure sensor, ensuring temperature drift does not exceed ±0.04%FS/℃.
• LCD Screen & Blue Backlight Display: Features a partitioned display for various measurements, providing direct readings for all parameters. The blue backlight enhances visibility in low-light conditions.
• Various Refrigerants Options: Includes a built-in PT (Pressure-Temperature) comparison table for 87 common refrigerants, facilitating convenient selection.
• Ničelna funkcija: Allows for zeroing out any deviation at the zero point to correct the system and ensure accurate measurements.
• Overload Warning Indications: Displays 'ALARM' on the screen for overload conditions. If the overload is excessively high, 'ALARM' and the backlight will flash simultaneously.
• Max/Min Value Display and Reset: Records maximum and minimum pressure values, with an option to reset these values.
• Auto Shut-Off Setting: Features an automatic shut-off function to conserve battery power during periods of inactivity.
• Adjustable Temperature and Pressure Units: Supports various temperature units (°C / °F) and pressure units (psi, kg/cm², cmHg, bar, kPa, Mpa, kg/cm²).
• 1/8-inch NPT Fitting: Equipped with a standard 1/8-inch NPT fitting for broad compatibility with various systems.

3. Nastavitev

3.1 Namestitev baterije

1. Poiščite pokrov predalčka za baterije na zadnji strani naprave.
2. Remove the cover by twisting or sliding it according to the markings.
3. Vstavite dve (2) bateriji AAA in pri tem pazite na pravilno polarnost (+/-), kot je označeno v notranjosti predala.
4. Varno namestite pokrov prostora za baterije.

3.2 Začetna povezava

1. Ensure the system to which the gauge will be connected is depressurized or isolated.
2. Carefully thread the 1/8'' NPT fitting of the digital pressure gauge onto the appropriate port of your HVAC or refrigeration system.
3. Tighten the connection firmly by hand, then use a wrench for a final snug turn to prevent leaks. Do not overtighten.

4.1 Vklop/izklop

• Za vklop naprave pritisnite Moč button (⏻) located at the top of the gauge.
• Za izklop naprave pritisnite in držite Moč button (⏻) for approximately 3 seconds until the display turns off.

4.2 Ničelna funkcija

The zero function is used to correct any minor deviations at the zero pressure point before taking a measurement.

• Ensure the gauge is disconnected from any pressure source and is at ambient atmospheric pressure.
• Pritisnite NIČ button (▶) located at the bottom right of the gauge. The display should show 0.000 psi (or selected pressure unit).
