TARE (TO WEIGHT DIFFERENT INGREDIENTS ON THE SAME KITCHEN SCALE) Leave the first ingredient weighed on the plate, press “TARE” button to reset the display to “0g”, add the next ingredient on the plate and the weight will appear on the display, and so on. UNIT EXCHANGE When “0g” displaying or weighing, press the “Unit” button on the base, you can choose the
unit of “g” “oz/lb”. SWITCH OFF OR AUTO OFF 1， After finish weighing, press “ON/OFF” button to switch off. 2， After finish weighing or if no any operation of the scale, the scale will automatically switch off after approximate 30 seconds. LOW BATTERY INDICATOR When the battery power is low, scale will display "Lo", please replace the battery in time. OVERLOAD INDICATOR When the scale is overloaded (over 5000g), “oL” will display on the LCD. Please remove the weight immediately to avoid the damage of the scale. ATTENTION 1， Place the scale on a hard and flat surface to ensure the greatest accuracy and reliability. 2， Do not use any chemical cleanser to clean the scale.
