Configuración
1. Instalación de la batería
The Keller LEO2 gauge operates on a 3V CR 2430 battery. To install or replace the battery:
- Localice la tapa del compartimiento de la batería en la parte posterior del dispositivo.
- Carefully open the cover by twisting or unlatching as indicated.
- Insert the CR 2430 battery, ensuring the correct polarity (+/-).
- Securely close the battery compartment cover to maintain the IP65 protection rating.

2. Conexión de presión
The gauge is equipped with a 7/16”-20 UNF pressure connection. An adapter for G 1/4” is included for common applications.
- Asegúrese de que el sistema de presión esté despresurizado antes de conectar el manómetro.
- Thread the gauge directly onto the pressure source or use the provided G 1/4” adapter if necessary.
- Tighten the connection firmly by hand, then use a wrench for a final snug fit, avoiding overtightening.
- Check for any leaks after pressurizing the system.

Instrucciones de funcionamiento
1. Encendido y apagado
Mantenga pulsado el INGRESAR button to power on the device. The gauge will automatically power off after a period of inactivity to conserve battery life. To manually power off, press and hold the INGRESAR botón de nuevo.
2. Lecturas de la pantalla
The LEO2 features a dual display:
- El top display indicates the current, actual pressure reading.
- El bottom display shows either the maximum (MAX) or minimum (MIN) pressure recorded since the last reset.
The pressure is measured and updated twice per second.
3. Navigating Display Modes (MAX/MIN)
Utilice el SELECCIONAR button to toggle between displaying the MAX and MIN pressure values on the bottom display.
4. Resetting MAX/MIN Values
To reset the recorded maximum and minimum pressure values:
- Ensure the gauge is powered on.
- Mantenga pulsado el SELECCIONAR button until the MAX/MIN values on the bottom display reset to the current pressure.
