Note: If the measured value is outside the range of a gauge, the needle will not be displayed. The digital value below
the gauge will still show the measured value.
• Oil Press: Displays engine oil pressure. Current coolant temperature is displayed directly below the gauge
at all times. The gauge registers oil pressure between 0-100 psi (0-689 kPa). Normal operating pressure is
between 35-80 psi (241-552 kPa).
• Coolant Temp: Displays engine coolant temperature. Current coolant temperature is displayed directly
below the gauge at all times. The gauge displays coolant temperature between 150°-250°F (66°-121°C).
Normal operating temperature of the unit is between 180°-200°F (82°-93°C) with an average ambient air
temperature of 70°F (21°C).
• Battery: Displays the engine battery voltage. Current battery voltage is displayed directly below the gauge
at all times. The gauge displays battery voltage between 0-50V. A normal reading is 12-14V on 12 volt
systems and 24-26V on 24 volt systems (with the engine running).
