OPERATION

ZEROING THE DISPLAY

You can press the ZERO 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 Weight
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 ZERO to
rezero the scale if small amounts of weight are shown when the platform is empty.
TARING
There are two methods to enter a tare value. The first uses the weight on the platform
and the second uses a value input by the user.
First Method:
Zero the scale by pressing the ZERO 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 TARE 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 "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 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 ZERO key was last pressed.
