6. Setup
6.1. Installazzjoni tal-batterija
- Locate the battery compartment cover at the rear of the device (refer to Figure 5).
- Iftaħ l-għatu bir-reqqa.
- Insert the 3V CR 2430 batteries, ensuring correct polarity as indicated inside the compartment.
- Agħlaq sewwa l-għatu tal-kompartiment tal-batterija.
6.2. Konnessjoni tal-Pressjoni
- The LEO2 features a 7/16"-20 UNF pressure connection. An adapter for G 1/4" is included for broader compatibility.
- Attach the appropriate adapter (if needed) to the gauge's pressure connection.
- Securely fasten the gauge (with or without adapter) to your pressure source. Ensure all connections are tight and leak-free. Use appropriate sealing materials (e.g., PTFE tape) if necessary to prevent leaks.
7. Operazzjoni
7.1. Power On/Off
The LEO2 Digital Pressure Gauge powers on automatically when any button is pressed. To conserve battery life, the device will automatically power off after a period of inactivity.
7.2. Qari tal-Wiri
The gauge features a dual display:
- Wirja ta' Fuq: Shows the current actual pressure reading.
- Bottom Display: Shows either the maximum (MAX) or minimum (MIN) pressure recorded since the last reset.
7.3. Selecting Display Mode (MAX/MIN)
Use the 'SELECT' button (typically on the left) to toggle between displaying the MAX and MIN pressure values on the bottom screen.
7.4. Resetting MAX/MIN Values
To clear the recorded MAX and MIN pressure values, press and hold the 'ENTER' button (typically on the right) until the values reset.
8. Manutenzjoni
8.1. Sostituzzjoni tal-batterija
When the battery indicator appears on the display or the device fails to power on, it is time to replace the batteries. Refer to section 6.1 'Battery Installation' for detailed instructions.
8.2. Tindif
Naddaf il-barra tal-apparat b'artab, damp drapp. Tużax prodotti tat-tindif li joborxu, solventi, jew kimiċi ħarxa, għax dawn jistgħu jagħmlu ħsara lis-casing or display. Ensure no liquid enters the pressure connection or display area.
8.3. Ħażna
When not in use for extended periods, store the LEO2 Digital Pressure Gauge in its protective carrying case (refer to Figure 7) in a dry, cool place, away from direct sunlight, extreme temperatures, and corrosive substances.
