5. OPERATION
5.1. ZEROING THE DISPLAY
You can press the
key at any time to set the zero point from which all other weighing and counting is
measured, within 10% 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. When the weight goes over 20 % of the full capacity, “read zero” function is obsolete.
5.2. 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 pres-
sed..
5.3. 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.
5.4. 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 percentage of the original sample. For example is 350g is placed on the scale and the
key is pressed the display will show 100.00%.
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.
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.
