Setup
1. Instalacija baterije
- Pronađite poklopac odjeljka za bateriju na stražnjoj strani uređaja.
- Open the cover and insert three (3) AAA batteries, ensuring correct polarity (+/-).
- Čvrsto zatvorite poklopac odeljka za baterije.
2. Connecting the Gauge
- The PG-30Pro is equipped with a standard 1/8-inch NPT fitting.
- Ensure the system you are connecting to is compatible with this fitting size.
- Carefully thread the gauge onto the system's pressure port. Do not overtighten.
- Verify a secure, leak-free connection before proceeding with measurements.

3. Zeroing Function
Before taking a measurement, especially in a new environment or after a long period of storage, it is recommended to zero the gauge. With no pressure applied, press the NULA button to reset the reading to zero. This corrects any potential deviation and ensures accurate measurements.
4. Max/Min Value Recording
The gauge automatically records the maximum and minimum pressure values during operation. To view these values, press the SET button repeatedly until "MAX" or "MIN" appears on the display. To clear these recorded values and start a new recording cycle, press and hold the NULA dugme dok viewing the MAX/MIN display.
