[. . . ] Do not immerse the prode in rhe water / soup over 212°F (100°C) more than 1 minute. Meter / Soup containing potassium and magnesium will make the measured reading higher than actual Meter / Soup containing starch or in jelly form will make the measured reading lower than actual Oil in soup will attach on the surface of the probe head that will affect the measurement result so remove oil layer on soup before measure Meter / Soup must be stirred well before measurement The meter must be immersed into soup for at least 5 seconds to take the measurement During measurement, probe head must be apart from the surface of container for at least 1 cm Only the probe head can be immersed into water. The main body is not waterproof design so cannot be clean under water. [. . . ] BATTERY COMPARTMENT Accommodates four LR43 batteries H. SENSOR COVER Protects the sensors when not in use - - SPECIFICATIONS LCD display Salt concentration level : 7 bars for salinity level and 2½ digit temperature display. : 0. 3%, 0. 6%, 0. 8%, 1. 0%, 1. 3%, 1. 7%, 2. 0% HOW TO USE YOUR SALINITY SENSOR 1. All components of the display panel will light up for one second. Then the LCD will return to off, except the temperature indicator (°C/ °F), which will be flashing. The unit is now in "Standby" mode. 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. Allow at least five seconds for the most accurate reading. The final readings will appear and stay. Note: Temperature measurement range is between 23°F to 212°F. If the measured temperature is out of this range the temperature display will continue to flash. The Salinity Sensor is permanently set for °F or °C at the factory. Release the ON button and remove the sensor from the liquid. The display screen will continue to show the salinity and temperature reading from the liquid just measured. Press the ON Button once again to turn the Salinity Sensor off. The sensor will also turn itself off automatically if left idle for thirty seconds. Applicable liquid temperature : 30°C ­ 70°C (86°F ­ 158°F) Temperature measuring range : -5°C ­ 100°C (23°F ­ 212°F) Response time: Maximum liquid temperature Power approx. 5 seconds : 212°F ( sensor in the liquid not exceed 1 minute) : 4 x LR43 1. 5V batteries SPECIAL CAUTION This product is designed for use with liquids only--not intended for use as a medical diagnostic tool for children or adults. FIG. [. . . ] When the batteries are running low, the low-battery indicator will light up. Replace the old batteries with new ones. Replace the battery compartment door.
