6. Настройка

6.1. Устаноўка батарэі

1. Locate the battery compartment cover at the rear of the device (refer to Figure 5).
2. Асцярожна адкрыйце вечка.
3. Insert the 3V CR 2430 batteries, ensuring correct polarity as indicated inside the compartment.
4. Надзейна зачыніце крышку батарэйнага адсека.

6.2. Падключэнне пад ціскам

1. The LEO2 features a 7/16"-20 UNF pressure connection. An adapter for G 1/4" is included for broader compatibility.
2. Attach the appropriate adapter (if needed) to the gauge's pressure connection.
3. 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. Аперацыя

7.1. Уключэнне/выключэнне харчавання

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. Паказанні дысплея

The gauge features a dual display:

• Верхні дысплей: Shows the current actual pressure reading.
• Ніжні дысплей: 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. Тэхнічнае абслугоўванне
