Then the LCD will return to off, except the temperature indicator (°C/ °F), which will be flashing. Insert the tip of the Salinity Sensor into the liquid you want to measure until the sensors are immersed. The Salinity Sensor will start measuring the salinity and temperature of the liquid, during which time the salinity indicators on the LCD screen will light up one by one, and the temperature display will blink.
