You can press the
key at any time to set the zero point from which all other weighing and counting is measured, within 4% of
power up zero. This will usually only be necessary when the platform is empty. When the zero point is obtained the display will show
the indicator for zero.
The scale has an automatic rezeroing function to account for minor drifting or accumulation of material on the platform. However you
may need to press the
key to rezero the scale if small amounts of weight are shown when the platform is empty.
tArINg
Zero the scale by pressing the
key if necessary. The zero indicator will be on.
Place a container on the platform, 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 value is subtracted from the
display, leaving zero on the display. The “TARE” indicator will be on. As product is added only the weight of the product will be shown.
The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added
after taring will be displayed.
When the container is removed a negative 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 platform is back to
the same condition it was when the
key was last pressed.
