power up zero. This will usually only be necessary when the platform is empty. When the zero point is obtained the disaply will show

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
WEIGHING A SAMPLE
To determine the weight of a sample first tare the empty container then place the sample in the container. The display will show
the weight and the units of weight currently in use.
PERCENT WEIGHING
The scale will allow a sample weight to be shown as 100%. Then any other weight placed on the scale will be displayed as a percen-
tage of the original sample. For example is 350g is placed on the scale and the
100.00%.
Removing the 350g weight and putting a 300g weight on the scale the display will show
350g.
Note: the scale may jump by large numbers unexpectedly if small weights are used to set the 100% level. For example if only 23.5g
is on a scale with 0.5g increments and the scale is set to 100%, the display will show 100.00%, however a small change of weight will
cause the display to jump to 102.13% as one scale division (0.5g) increase to 24.0g will be equivalent to a 2.13% increase.
Removing the 350g weight and putting a 300g weight on the scale the display will show 85.71% as 300g is 85.71% of 350g.
Pressing the
key will return the scale to weighing.
