5.2. Pressure Connection
The device features a G1/4" pressure connection. Before connecting to a pressure source, ensure the connection point is clean and free of debris. Use appropriate sealing materials (e.g., PTFE tape) if necessary, and tighten the connection firmly but without excessive force to prevent damage. Verify that the pressure medium is compatible with the device's stainless steel (AISI 316L) wetted parts.
5.3. L-Ewwel Tixgħil
After battery installation and pressure connection, the device should power on automatically or by pressing one of the control buttons. The digital display will show the current pressure reading. Allow a few moments for the device to stabilize.
6. Operazzjoni
The LEO Record Manometer is operated using two buttons: AGĦŻEL u DĦUL. The left key (AGĦŻEL) is used to turn the instrument on, to select functions, and to scroll through options. The right key (DĦUL) executes the selected function or unit.
6.1. Funzjonijiet ewlenin
- ŻERO: The ZERO function allows you to set any value as a new zero reference. This is useful for relative pressure measurements.
- UNITAJIET: All standard measurement units are calibrated in the instrument. The pressure can be displayed in various units, such as bar, mbar/hPa, kPa, MPa, psi, kp/cm², mH₂O. Use the AGĦŻEL button to cycle through available units and DĦUL biex tikkonferma l-għażla tiegħek.
- REKORD: The record function can be started or ended with the operating keys. The configuration of the record takes place via the interface/software.
