In addion ther are labels for TARE, GROSS weight, Zero and for Low baery.
6. OPERATION
6.1. ZEROING THE DISPLAY
You can press the key at any me to set the zero point from which all other weighing and counng is
measured, within +/-2% of power up zero. This will usually only be necessary when the plaorm is empty.
When the zero point is obtained the display will show the indicator for zero.
The scale has an automac rezeroing funcon to account for minor driing or accumulaon of material on
the plaorm. However you may need to press the key to rezero the scale if small amounts of weight
are shown when the plaorm is empty.
6.2. TARING
Zero the scale by pressing the key if necessary. The zero indicator will be on.
Place a container on the plaorm, a value for its weight will be displayed.
Press the key to tare the scale. The weight that was displayed is stored as the tare value and that va-
lue is substracted from the display, leaving zero on the display. The “NET” indicator will be on. As product
is added only the weight of the product will be shown. The scale could be tared a second me if another
type of product was to be added to the rst one. Again only the weight that is added aer taring will be
displayed.
When the container is removed a negave value will be shown. If the scale was tared just before removing
the container this value is the gross weight of the container plus all product that was removed. The zero
indicator will also be on because the plaorm is back to the same condion it was when the key was
last pressed.
6.3. WEIGHING A SAMPLE

The display will show the weight and the units of weight currently in use.
