In order to work the scale, the scale must be on. One the scale is on, it will initialize, then it will be ready to weigh and count. Place the object(s) that you want to weigh or count on the scale. The scale has to be programmed beforehand on the weight of one object so it can count the amount of objects on the scale. One the scale weighs the object(s), the liquid crystal display (LCD) will present the weight of the object(s) and how many there are. The light above the LCD will turn either red, yellow, or green (red if it’s low stock, yellow if it’s running low on stock, or green if it’s well-stocked). At the back of the scale is a tare button so that the user can zero out the scale.
